In This Chapter Overview Performance Monitoring Physical Description Functional Description Communication Ports Outputs Reference Inputs and TOD Sources Alarms 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 23 Chapter 1 Overview of the TimeCreator 1000 Overview Overview The TimeCreator 1000, shown in Figure 1-2, is a DOCSIS Timing Interface (DTI) Server that delivers accurate timestamp and frequency synchronization, and with GPS it can also provide Time of Day (TOD) to DTI client elements in a Modular Cable Modem Termination System (M-CMTS) architecture. M-CMTS elements shown in Figure 1-1 (Edge QAMs, Upstream Receivers, M-CMTS Core, etc.) use DTI to synchronize the DOCSIS Timestamp and Symbol Clock used in the DOCSIS communications between modems and the headend/hub. The TimeCreator 1000 functions as either a root server or subtending server. The root server is at the top of a server hierarchy and is the source of traceable time and frequency for all subtending DTI servers and clients in a building. The subtending server receives its time and frequency reference through a direct connection to a root server's DTI link connector; a subtending server cannot be referenced to another subtending server. Figure 1-1. 24 DTI Server Hierarchy and M-CMTS Elements TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 1 Overview of the TimeCreator 1000 Overview A TimeCreator 1000 in a root server configuration can use either its internal clock as the master frequency for the headend/hub meeting DOCSIS specifications, or it can be configured to use GPS. GPS is required for Business Services over DOCSIS (BSoD), which allows you to deliver T1, E1, and NxDSO emulation services. GPS is also required to implement Network Time Protocol (NTP) server mode, which allows common time between headends/hub and other applications. NTP, the user-specified time, and the IMC's real-time clock (RTC) can also be used as a basis for the DOCSIS timestamp to provide system TOD for operation in free-run mode only. The TimeCreator 1000 features include: 10+2 DTI Ports - 10 standard DTI Client Connections (6 for 8-port option) - 2 dual mode DTI Connections for use as a standard DTI Client Connection or input from a Root DTI Server with Carrier-Class Performance Optional High Reliability Redundant Operation SNMP and CLI management over SSH, Telnet and Craft port DTI Client Health Monitoring NTP Server Option TOD and BSoD Support (requires GPS input) Compact 1RU Design AC and DC Power Options Subtending of up to Twelve DTI Servers DTI Server Configurable with Dual Path Protection and 24 Hour Holdover Software Upgradeable Figure 1-2. TimeCreator 1000 Front View Figure 1-3. TimeCreator 1000 Rear View 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 25 Chapter 1 Overview of the TimeCreator 1000 Overview Shelf The TimeCreator 1000 shelf requires a minimum of three plug-in modules to operate: Power Supply module Input/Output/Clock (IOC) module Information Management Card (IMC) module. It is recommended that a second Power Supply module and IOC are added to the configuration for redundant operation. Since the TimeCreator 1000 provides the Master DOCSIS Clock and Timestamp for the entire Headend or Hub site, it is designed to provide high reliability through redundancy, although redundancy is not required. The flexibility of configuration and therefore cost enables various deployment scenarios for root, slave, and protected architectures. Input Signals The TimeCreator 1000 can use either GPS or DTI signals as external input references to acquire the system's frequency, DTI timestamp, and TOD alignment. NTP and the user-specified time from the IMC's real-time clock (RTC) can also provide system TOD with much less accuracy. See Table 1-1 for descriptions. Only GPS can provide a common timestamp across the network for a distributed M-CMTS deployment. It is suggested that all root TimeCreator 1000 servers be configured with GPS. Upgrading any DTI Server from a user time or NTP time to GPS for BSoD or distributed M-CMTS architectures will require resetting the DOCSIS Timestamp and thus re-range all cable modems. The GPS input connects to the TNC connector on the IMC and the DTI input from a root DTI Server connects to the rear panel port A and port B RJ-45 connectors (labeled A/11 and B/12). NTP runs on the IMC's management Ethernet port. Note: When ports A/11 and B/12 are provisioned as outputs, they are referenced as Ports 11 and 12. 26 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 1 Overview of the TimeCreator 1000 Overview Table 1-1. TimeCreator 1000 Input Signal Source Input Source Description GPS GPS antenna used to acquire the system's frequency, DTI timestamp, and TOD. DTI External DTI signals used as external input references to acquire the system's frequency, DTI timestamp, and TOD. NTP NTP server used to acquire the TOD. Frequency is provided by IOC's clock in freerun mode. Real-Time Clock USER Clock on IMC used to acquire the TOD. Frequency is provided by IOC's clock in freerun mode. User manually enters TOD. Frequency is provided by IOC's clock in freerun mode. DTI Input Priority Level You can assign a priority level to each DTI input and the value determines which input is used as the system reference. The range is 1 to 5 and the lower the priority level, the higher the priority. Use the Set Interface Priority command to provision these parameters. Setting the Input Reference Switching Mode The DTI reference selection at ports A and B can be either revertive or non-revertive (see Provisioning Revertive and Non-Revertive Mode, on page 94). In the revertive mode, if an input used as the system reference is disqualified (for any reason), the reference switches to the next-highest input and reverts to the initial input when that input is re-qualified. In this mode, the reference switches two times: once when the disqualifying event occurs, and again when the initial input is re-qualified. In the non-revertive mode, the system reference switches to the next-highest input but does not revert to the initial input when the initial input is re-qualified. The system reference switches only once when the disqualifying event occurs. Revertive mode is used when the port priorities are different and non-revertive mode is used when the priorities are the same. 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 27 Chapter 1 Overview of the TimeCreator 1000 Overview Output Signals The TimeCreator 1000 passes frequency and TOD output through rear panel DTI links. Ports 1 through 10 (12-port version) or Ports 1 through 6 (8-port option) are permanent output ports. Ports A/11 and B/12 can be provisioned as either outputs or inputs. Note: When ports A/11 and B/12 are provisioned as inputs, they are referenced as ports A and B. Communications Ports The EIA-232 serial and Ethernet connections are located on the IMC. The EIA-232 serial and Ethernet connections allow you to provision the system from a terminal or computer running a terminal emulation application. Local Craft Serial Port The EIA-232 port supports local control; you can configure the TimeCreator 1000 with commands using a terminal or personal computer (PC) with terminal emulation software (see Communicating Through the Serial Port, on page 72). The connector is located on the IMC. The Local port is configured as a DCE interface and the default specifications are as follows: 8 data bits 1 stop bit no parity 9600 baud rate (57600 is supported only in the IMC rev H version 1.00.13 or below) Flow Control: None Ethernet An Ethernet connector provides connectivity to a local area network (LAN) and each port can be assigned a unique internet protocol (IP) address (see Communicating Through the Ethernet Port, on page 72). Once the IP address is set and a connection is made, you can access the TimeCreator 1000 on an intranet. The Ethernet port supports two simultaneous connections to port 23. 28 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 1 Overview of the TimeCreator 1000 Overview Clock Design The TimeCreator 1000 clock design includes a highly stable ovenized Quartz crystal to produce accurate synchronization outputs. In a dual-IOC configuration, the clock function is redundant to provide protection. Each IOC qualifies the input signal and filters jitter and wander noise elements that may exist. In the event that all input references are lost or disqualified, the unit goes into holdover mode with the oscillator providing the system reference. The IOC meets Type III performance. Operating Modes The TimeCreator 1000 has the following operating modes: Warm-up - The period immediately following power-up that allows local oscillator stabilization required for stable frequency generation from the system. Free-run - This operating mode allows the system to generate a DTI output that has stable generation of frequency and TOD when the system has no external frequency reference (GPS or DTI). TOD can be from NTP, a user-specified time, or from the IMC's real-time clock. Fast-Lock (Acquire) - In this mode the system quickly locks the local oscillator frequency to another frequency source (GPS or DTI reference) to establish the system's frequency and TOD. Normal (Locked) - In this operating mode, the system's output frequency and TOD are tracking the reference frequency (GPS or DTI) and TOD within the DTI specified requirements. Bridging - If all input references are lost, the TimeCreator 1000 goes into bridging mode. In this mode, the outputs continue to provide accurate timing for a limited period. If the system qualifies the reference prior to the end of the bridging time, the system re-enters Fast-Lock or Normal operation mode. If the inputs are not re-qualified before the bridging time has elapsed, the TimeCreator 1000 enters holdover mode. Holdover - If the reference signal is lost and not re-qualified when the bridging time elapses, the clock enters holdover mode. The accuracy of the TimeCreator 1000 output is then dependent on the quality level of the oscillator. Extended Holdover - If the clock remains in holdover for an extended duration, typically 4 hours, the clock enters extended holdover mode. 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 29 Chapter 1 Overview of the TimeCreator 1000 Performance Monitoring Frequency Mode - In this operating mode, the system's frequency is tracking the reference frequency (GPS). In this mode, a user can add a GPS reference to the TimeCreator 1000 and use the frequency from GPS to meet BSoD specifications without re-setting the DOCSIS Timestamp and causing a re-ranging of the cable modems. Note: In Frequency Mode, DTI output and IMC GPS are not in sync. Performance Monitoring Server Status Monitoring DTI client status log files provide information on client status, oscillator type, and the server's cable advance flag and cable advance value. Phase Measurements TheTimeCreator 1000 measures phase data. Peak to peak jitter and MTIE results are calculated for the user. Frame error rate (FER) is also calculated and made available to the user. It is calculated over a 10-second window. MTIE Calculations MTIE is a measure of the relative noisiness of a signal that relates to frequency offsets and phase transients. The TimeCreator 1000 automatically calculates MTIE for each enabled input from the most recent 1000 seconds. From this calculation, you can retrieve MTIE values for 35-second and user-configurable windows. You can set an alarm threshold for each of these windows; if the MTIE value exceeds this threshold and the alarm is enabled, the TimeCreator 1000 generates an alarm. Physical Description The TimeCreator 1000 consists of a 19-inch (48 cm) rack mount shelf, plug-in modules, AC power supply cables and optional GPS cables, and hardware. Note: 23-inch (58.42 cm) rack mounting brackets are also available as a separately ordered item. 30 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 1 Overview of the TimeCreator 1000 Functional Description The front of the TimeCreator 1000 has two IOC module slots and one IMC module slot. The rear has two power supply slots, twelve DTI link connectors and two BITS connectors (see Figure 1-4). The minimum configuration is one Power module, one IOC module, and an IMC module. The second IOC and Power module slots are available for redundancy. Note: The BITS connectors are not functional in this release. Input/Output Clock (IOC) AC Power Supply Figure 1-4. Information Management Card (IMC) DTI Client/Server Links DTI Client Links Input/Output Clock (IOC) AC Power Supply TimeCreator 1000 Modules and DTI Links Functional Description The TimeCreator 1000 accepts one GPS input and two DTI inputs for system reference and it allows you to provision the DTI input reference priority. When a GPS or DTI reference is qualified as the system reference, the server uses the qualified reference to acquire the system's frequency, DTI timestamp, and TOD alignment. The TimeCreator 1000 rear panel has ten DTI client links (six DTI client links for 8-port option) and two client/server links. Client links connect to an M-CMTS Core, Upstream receiver, Edge QAM, or DTI server. Server links allow a subtending server to receive time and frequency signals from a DTI root server. There are also two T1/E1 BITS frequency inputs. Note: The BITS connectors are not functional in this release.

IOC Module Block Diagram IOC Module The IOC module has LED status indicators and test outputs for the system. The LEDs indicate: Power Status Active Status Output Status External Reference Status Alarm Status Holdover Status The test output connectors provide a 10.24 MHz master clock signal and a 10 kHz DTI frame clock signal. IMC Module Connectors for Ethernet management, NTP time server, EIA-232 serial, and the Two-Way GPS Timing Antenna connections are located on the IMC module. The IMC's LEDs indicate the following: Power Status Alarm Status GPS Signal Status 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 33 Chapter 1 Overview of the TimeCreator 1000 Communication Ports Power Module The TimeCreator 1000 allows either -48 V DC power connection, or 120/220 V AC power connection depending on the type of module used. The LED indicates power status. Rear Panel Connectors The TimeCreator 1000 rear panel connections are RJ-45 connectors. There are ten permanent DTI client connectors and two DTI client/server connectors that can be provisioned as either client or server links. This allows the TimeCreator 1000 to support up to 12 DTI client links (8 DTI client links for 8-port option), or when provisioned as a subtending server to receive two time and frequency references. There are also two BITS connectors. Each DTI link connection has associated LEDs that indicate connection status. Note: The BITS connectors are not functional in this release. Communication Ports Communications ports on the IMC allow you to provision, monitor, and troubleshoot the shelf. You communicate with the TimeCreator 1000 using either CLI or SNMP protocols. Local Craft Serial Port The EIA-232 port supports local control; you can configure the TimeCreator 1000 with CLI commands using a terminal or personal computer (PC) with terminal emulation software (see Communicating Through the Serial Port, on page 72). The connector is located on the IMC. The Local port is configured as a DCE interface and the default settings are as follows: 34 Baud = 9600 baud rate (57600 is supported only in the IMC rev H version 1.00.13 or below) Word Length = 8 bits Parity = None Stop bits = 1 Software Handshaking, Xon/Xoff TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 1 Overview of the TimeCreator 1000 Outputs Management Ethernet Port The Management Ethernet connector provides connectivity to an Ethernet local area network. Each Ethernet port has a unique internet protocol (IP) address and once the IP address is set and a connection is made to a LAN, you can access the TimeCreator 1000 (see Communicating Through the Ethernet Port, on page 72). NTP Server Ethernet Port The NTP server port serves the TimeCreator 1000's system time to external NTP clients. The NTP server option only works with a TOD-source of GPS. This Ethernet port is configured separately from the management port (see Provisioning an NTP Server, on page 104). The NTP server option requires the purchase of a license. Outputs The DTI link connectors use a single pair for transmission in both directions. The server and client alternate data transmission therefore eliminating the need for a crossover connection. The DTI server output is a Manchester encoded frame with an underlying bit-rate of 5.12 Mbps locked to the DTI Master Clock. You can enable or disable each output individually through user commands (see the command Set Interface, on page 213). The TimeCreator 1000 automatically calibrates each DTI Output when a DTI Client is connected eliminating the need to manually compensate for cable lengths. The maximum cable length is 656 Ft. (200 m). The TimeCreator 1000 provides a 10.24 MHz master clock signal and a 10 kHz frame clock on the front panel. Reference Inputs and TOD Sources The TimeCreator 1000 can use either GPS or DTI signals as external input references to acquire the system's frequency, DTI timestamp, and TOD alignment. The GPS reference signal input connects to a TNC connector on the IMC module and the DTI reference signal input is connected to RJ-45 connectors labeled A/11 and B/12 on the rear panel. The Set Interface Priority user command allows you to set priority levels for the two DTI reference signals (see the command Set Interface, on page 213). Note: When ports A/11 and B/12 are provisioned as outputs, they are referenced as ports 11 and 12. 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 35 Chapter 1 Overview of the TimeCreator 1000 Alarms NTP, the user-specified time, and the IMC's real-time clock (RTC) provide system TOD for operation in free-run mode only, as shown in Table 1-1.The default settings provision the TimeCreator 1000 to operate in free-run mode only. Note: The BITS input connectors are not functional in this release. It is recommended that the root server in a DTI network with root and subtending servers be referenced to GPS. Using GPS allows the user to recover from root server outages with minimal cable modem re-ranging. The root server can be set to user mode and still provide protection from excessive re-ranging, but requires some additional network resources to enable an orderly network recovery from any major root outages. If, for example, a power outage affects the root server, it must have a way to recover the previous network time and phase when it returns to normal operation. To do this the TimeCreator has a 'Root-Server Recovery' function that re-synchronizes the root server to the rest of the network. To accomplish this there has to be a connection between the root server, port 12 and a subtending server port 1, with port 12 of the root server set as a Client, but not enabled. When the root server recovers power (or has been serviced) it will automatically query time from a subtending server so that it will not cause unnecessary cable modem re-ranging. See Provisioning Root Server Recovery Mode, on page 95 for details. Alarms The TimeCreator 1000 uses alarms to notify you when certain conditions are deteriorating below user-specified levels. These alarms are indicated by module status LEDs and by SNMP traps. You can provision the alarm to either be enabled or disabled and the current alarm state can be obtained via the communication ports. For more information, see Provisioning Alarms, on page 105 and Appendix A, Alarms, Events and SNMP Traps. 36 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 2 Engineering and Ordering Procedures This chapter describes the items available for the TimeCreator 1000, and lists the part number for each item.

The unit then operates in freerun after that, keeping time according to its local oscillator frequency. The user can force an update in the User and NTP modes. In GPS mode, the initial time is set from GPS, and the unit maintains frequency and phase lock to GPS. When recovering from extended holdover, the frequency is locked to the GPS reference. If the phase error is small, the phase is corrected by slewing. If the phase error is large, an alarm is generated and the user will need to manually correct the phase. This prevents unmanaged discontinuities of the DOCSIS time stamp. Table 4-1. TOD Source Modes TOD Source Initial Time Frequency Lock Phase Lock RTC (Default) Real-time clock Freerun Freerun User User Freerun Freerun NTP NTP Freerun Freerun GPS GPS GPS GPS DTI (subtending) Root server Root server Root server GPS For details on proper installation of the GPS antenna, refer to Appendix C. Proper cable, grounding techniques, and lightning arrestors should be used. Mount the antenna outside, preferably on the roof with a clear view of the sky. Do not mount the antenna near a wall or other obstruction blocking part of the sky. Mount the antenna well above roads or parking lots. Allow at least one hour for the unit to track and lock to GPS. NTP Client Mode If the system time is off by more than four hours, then the system mode should be set to user mode and the time set to within four hours. The unit can then be configured to use NTP. 64 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 4 General Guidelines for using the Symmetricom TimeCreator 1000 DHCP Since the unit only sets the time once, the time could be off by more than 100 ms if this procedure is not followed. DHCP This unit's DHCP client will not continually attempt to acquire an IP address if the Ethernet cable is not connected at power up, or when DHCP mode is enabled. After the cable is connected, enter the following commands to restart DHCP: set ip-state eth0 disable set ip-state eth0 enable CLI commands Note: The "sync tod-source now" command used in some of the following examples forces the TimeCreator 1000 to immediately start using the new reference for time and frequency. This command is useful in lab tests, but its use should be carefully planned since it may cause cable modems to resync. Logging In And Out At the login prompt, enter the user name. At the password prompt, enter the password. The default administrator user name is "admin" with password "SymmTC1000". To logout, use the command "logout": Example Type logout and press Enter.

In the default condition, all IP addresses are allowed access. Once the first IP address has been added to the whitelist, any future IP sessions will only be accepted if they originate from IP addresses from the whitelist. This feature is useful when the management port is connected to a public network rather than a private network. Note: Symmetricom recommends that the IP address of the administrator station always be added to the whitelist first. This will prevent an accidental lockout of the administrator via Telnet/SSH. The whitelist must be committed before any changes to the whitelist will be implemented. Note: If the whitelist function is being use for a TimeCreator 1000 with the TOD-source of NTP, the local host address (127.0.0.1) should be added to the whitelist with the command "set whitelist add 127.0.0.1". Add an IP Address to the Whitelist Use the dot-decimal notation format xxx.xxx.xxx.xxx to enter the IP address parameter. 1. Login at the Admin level (see Login, on page 74). 2. To view the current list of IP addresses on the whitelist, type show whitelist and press Enter. 3. To add a specific IP address to the whitelist, type set whitelist add and press Enter. (For example, set whitelist add 192.168.5.10). 4. To add IP addresses using a subnet mask, type set whitelist add / and press Enter. The mask indicates which parts of the IP address are significant it is specified as a prefix number which is the number of 1s from the MSB with the remaining bits set to 0. A mask of 255.255.255.0 is set with the value 24. (For example, set whitelist add 192.168.5.0/24) The default value is 32, or 255.255.255.255, to match the full 32-bit IP address. . 5. Type set whitelist commit and press Enter. 78 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 5 Provisioning Provisioning Login Authentication Delete an IP Address From the Whitelist 1. Login at the Admin level (see Login, on page 74). 2. To view the current list of IP addresses on the whitelist, type show whitelist and press Enter. 3. Type set whitelist delete and press Enter. (For example, set whitelist delete 192.168.5.10). 4. Type set whitelist commit and press Enter. Set the Whitelist to Default 1. Login at the Admin level (see Login, on page 74)). 2. Type set whitelist default and press Enter. Provisioning Login Authentication The authentication scheme used in the TimeCreator 1000 allows you to provision either a RADIUS or TACACS+ server IP address and authentication key(s) for server access. If RADIUS or TACACS+ is enabled, the system allows local login if the server doesn't authenticate the user and the user is configured locally. Provisioning the TC1000 for Login Authentication RADIUS Server To provision the TC1000 with the RADIUS server IP address and the authentication key for server access: 1. Login at the Admin level (see Login, on page 74). 2. Type set authentication radius address

Type set authentication radius key and press Enter (key is up to 32 ASCII characters). 4. Type set authentication radius state enable and press Enter. 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 79 Chapter 5 Provisioning Provisioning Login Authentication TACACS+ Server To provision the TACACS+ server IP address and the authentication key for server access: 1. Login at the Admin level (see Login, on page 74). 2. Type set authentication tacacs+ address
[:] and press Enter (address is the server IP address, for example 192.168.0.10, and the port # is optional). 3. Type set authentication tacacs+ key and press Enter (key is up to 32 ASCII characters). 4. Type set authentication tacacs+ state enable and press Enter. Configuring the RADIUS Server For a FreeRADIUS server (see http://www.freeradius.org/), configuration requires placing the TimeCreator 1000 user information in the file "/etc/raddb/users.conf". For other RADIUS servers, see the appropriate user documentation for information on how to configure the server. The "Class" attribute from the RADIUS server is used by the TimeCreator 1000 to indicate the security level for each authorized user, as described in the Table 5-2 below:. Table 5-2. Security Levels vs. RADIUS Server Class Attribute Settings TimeCreator 1000 Security Level RADIUS Server "Class" Attribute User 1-4 Power-user 5-9 Admin 10 - 15 Listed below are example configurations for the file "/etc/raddb/users.conf" for the FreeRADIUS server. Example 1: "Admin"-Level User For user "usr_a" with a password of "test1a": usr_a Auth-Type := Local, User-Password == "test1a" Class= "15" Example 2: "Power-User"-Level User 80 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 5 Provisioning Provisioning Login Authentication For user "usr_b" with a password of "test2b": usr_b Auth-Type := Local, User-Password == "test2b" Class= "8" Example 3: "User"-Level User For user "usr_c" with a password of "test3c": usr_c Auth-Type := Local, User-Password == "test3c" Class= "1" The RADIUS client and secret key must also be configured in the RADIUS server. For a FreeRADIUS server, this is configured in the "/etc/raddb/clients.conf" file. Example client 192.168.0.0/16 { secret= testing123 shortname= private-network-2 } Note: When using the TimeCreator's "show user" command, users logged in remotely via RADIUS will be displayed as (remote), rather than just for local users. Note: If you change the "Class" attribute in the file "/etc/raddb/users.conf", you need to use the "set user del" command to delete the TimeCreator's stale user account (if it exists) for your remote RADIUS user. Then log in to TimeCreator again so the TimeCreator 1000 will recreate the user account for your remote RADIUS user with the new user security level corresponding to new "Class" attribute you specified in the file "/etc/raddb/users.conf". 097-93100-01 Revision C - February, 2010 TimeCreator 1000 User's Guide 81 Chapter 5 Provisioning Provisioning Login Authentication Configuring the TACACS+ Server For the Cisco TAC_PLUS TACACS+ server, configuration requires placing the TimeCreator 1000 user information in the file tac.cfg. For other TACACS+ servers, see the appropriate user documentation for information on how to configure the server. The "priv-lvl " attribute from the TACACS+ server is used by the TimeCreator 1000 to indicate the security level for each authorized user, as described in the Table below:. Table 5-3. Security Levels vs. RADIUS Server Class Attribute Settings TimeCreator 1000 Security Level TACACS+ Server "priv-lvl" Attribute User 1-4 Power-user 5-9 Admin 10 - 15 Listed below are example configurations for the file "tac.cfg" for the Cisco TAC_PLUS TACACS+ server.

Provisioning Services Using the Set Service command, you can control the TimeCreator 1000 services (see Set Service, on page 250). This command allows you to enable or disable the following services: EIA-232 Telnet SSH NTP SNMP Example To enable NTP, enter the following command: Type set service ntp enable and press Enter. Provisioning the Ethernet Ports The TimeCreator 1000 supports static IP addresses as well as dynamically allocated addresses on the MGMT (Management) port and NTP port. The dynamically allocated address requires a connection to a DHCP server. When provisioning the unit for static IP address, you can set the Host address, Mask address, and Gateway address, or you can set the addresses to the factory default. See Appendix D, Specifications and Factory Defaults for default IP addresses. Static IP Mode Use the following procedure to configure the TimeCreator 1000 IP parameters (Host Address, Subnet Mask, and Gateway Address) on the MGMT port. Use the dot-decimal notation format xxx.xxx.xxx.xxx to enter the address parameter. 84 TimeCreator 1000 User's Guide 097-93100-01 Revision C - February, 2010 Chapter 5 Provisioning Setting the System Date, Time and Time Offset Example 1.

DHCP Mode You can either enable or disable DHCP mode on the MGMT port or NTP port. Use the following procedure to configure the TimeCreator 1000 to enable DHCP on the MGMT port. Example 1. Login at the Admin or Power-User level (see Login, on page 74). 2. Type set ip-mode eth0 mode dhcp and press Enter. 3. Type set ip-state eth0 restart and press Enter. Setting the System Date, Time and Time Offset The TimeCreator 1000 Time of Day can be set either by an external source, or manually with the Set Clock command. You can set the time and date only in the user tod-source mode. The local time offset only affects the time associated with the logs. Use the following procedure to manually set the system date, time, and time offset: 1. Login at the Admin or Power-User level (see Login, on page 74). 2. Type set tod-source user and press Enter. 3. Type set clock date time
