System Release Notice
TimeCreator 1000
DOCSIS Timing Interface Server
Version 1.2
Introduction
This document provides information about Versions 1.02.03 IMC (Information Management
Card) and 1.02.03 IOC (Input/Output Clock) of Symmetricom's TimeCreator DOCSIS Timing
Interface Server. Please refer to Updating the Firmware, on page 4 of this release note for
upgrade instructions.
Notes
CLI default administrator user name is "admin" and default password is "SymmTC1000"
DNS is not supported. Therefore, hosts must be entered with IP addresses, not hostnames.
Path location message and reverse path traceability messages defined in I03 of the DTI
specification are not supported.
During power-up and rebooting, messages will be displayed on the EIA-232 console port.
The messages are normal and should be ignored.
The SNMP object DtiServerGlobalTodValue can be used to set date and time. However, the
MJD, timezone, and leapsecond fields are ignored. Setting multiple objects together is not
recommended and therefore not supported in this object. Timezone setting is available in
Symmetricom's Enterprise MIB. Refer to the MIB files on the CD.

Resolved Issues
24906: SSH does not work with RADIUS/TACACS+
08951: Incorrect configuration of Port 12 can inadvertently cause a timing loop in Root Server
Recovery (RSR) mode. The problem was fixed by prohibiting creation of the timing loop.
097-93100-02 Revision H – February 2010 Page 3
08904: Transient PLL unlock can cause IOC operational failure when changing the
TOD-source
24149: If SSH is disabled before upgrade and/or reboot, it is re-enabled after upgrade and/or
reboot
24094: GPS Latitude and Longitude will not be accepted if entered in lower case
06288: IMC and IOC communication alarm problems
22251: In a firmware upgrade, the session would block for 20 minutes if the specified host for
the upgrade files didn't exist. The block time has been set to 15 seconds to resolve this issue.
22293: Configurable IP addresses and masks can be set to reserved IP addresses
22353: The system does not support a timezone offset value of -3:30
22393: The Upgrade command limits the path plus filename to fewer than 60 characters
22373: The boundary check does not block invalid NTP keyID values (greater than 65534)
22275: After three failed login attempts, the server locks the user account
22270: No CLI command to view which users are logged in
23645: The fan health monitor sensitivity can lead to false failure alarms
23838: The system may turn on LEDs of unconnected DTI port numbers when certain DTI
ports are connected
23888: System is setting the "port unstable" alarm inconsistently
23935, 23734, 23912: Telnet and SSH malicious attacks can cause stack overflow and
resulting Telnet/SSH connection failure, out-of-memory messages, or IOC switch failure
22372: SNMP GetBulk requests with large repetition numbers are not supported, and may
cause a system lockup due to excessive data. Still not supported, but will not cause system
lockup.
23932: Possible problems with disabling Telnet and enabling FTP with “set service”
command.
“Show service” always displays FTP as disabled.
24446: Problem in restoring IMC configuration from a backup file on the IOC. IMC firmware
version 1.01.07 and later versions of the firmware include corrections to allow restoration of
the IMC configuration from a backup file on the IOC.
Known Issues
25479: The command "set firewall icmp enable" doesn't work sometimes. This is caused by
issuing the same "set firewall icmp disable" command multiple times in succession.
Workaround: If you are unable to ping your TimeCreator box after the "set firewall icmp
enable" command, repeat the "set firewall icmp enable" command until TimeCreator
responds to the ping request.
21966: A spurious interrupt message has occasionally been observed on the EIA-232
console port. An example message is “Spurious 8259A interrupt: IRQ7”.
Workaround: These spurious messages can be ignored.
Page 4 097-93100-02 Revision H – February 2010
Baud rate issue during firmware downgrade. After downgrading the IMC firmware from 1.2 to
1.0, the TimeCreator cli's serial port baud rate changes to 57600, but the IMC bootcode's
baud rate will still remain unchanged (9600).
Workaround: Ignore any garbled messages during bootup.
24138: If RADIUS server or TACACS+ server is enabled, it becomes disabled after upgrade.
Workaround: If Radius Server or TACACS+ server was enabled before upgrade, it has to be
re-enabled after upgrade.
09127: A TOD source of NTP does not work when a whitelist is used.
Workaround: Add local host IP address (127.0.0.1) to whitelist.
25524: Setting TOD source alone to or from GPS with “set TOD source” command will not
result in correct GPS LED state. If this happens with NTP Server function enabled, the NTP
Server function will not work.
Workaround: Set TOD source to or from GPS, followed by “set interface state gps
{enable|disable}.
Updating the Firmware
Upgrading the IMC
To upgrade the software in the IMC, use the following procedure:
Note: Outputs are not affected during the IMC upgrade procedure.
1. Login at the Admin level.
2. Type
set configuration backup and press Enter to save the contents of the IMC
configuration.
3. Type
upgrade imc <filename> <ftp-server> ftp auto-reboot (use the IP address
only) and press Enter. The auto-reboot option automatically reboots the unit after the
firmware is installed to activate it. Otherwise, the user must enter the command reboot IMC
when installation is complete.
Note: The system will FTP the file from the specified FTP server and then upgrade the
module.
4. When prompted, enter a user name and password for the server.
Note: If the file is not valid, the TimeCreator 1000 will reject it.
5. The TimeCreator 1000 validates the received file, and if the file is valid it updates the flash
memory and reboots the IMC.

Upgrading Redundant IOCs
When upgrading redundant IOCs, you should upgrade them one at a time if the unit is in service
and a service interruption needs to be avoided. When you enter the command without specifying
an IOC (such as IOC1 or IOC2), both IOCs are loaded with the firmware and a reboot is
necessary to activate it. Adding the auto-reboot option to the end of the upgrade command
sequences rebooting of the IOCs so that the standby IOC is rebooted first. The IMC waits until
that IOC is out of warmup, and then it is set active. At that point, the previously active IOC is
rebooted.
Note: Symmetricom recommends that redundant IOCs use the same firmware version.
To upgrade the software in both IOCs, use the following procedure:
6. Login at the Admin level.
7. Type
set configuration backup and press Enter to save the contents of the active IOC
configuration.
8. Type
upgrade ioc <filename> <ftp-server> ftp auto-reboot (use the IP address
only) and press Enter.
9. When prompted, enter a user name and password for the server. Note: The system will
FTP the file from the specified FTP server and then upgrade the module.
10. The new software is loaded into the IOC, the IOC is rebooted, and it then enters Warm-up
mode for up to 30 minutes.
If you are upgrading the active IOC, the TimeCreator 1000 performs the following:
– the active IOC enters standby mode
– the second IOC changes to active mode
– firmware is transferred to the standby IOC
After the download, the standby IOC must achieve Lock mode before changing back again
to active mode. The standby IOC is then upgraded.
Note: If the initial IOC upgrade is not successful, the entire process is aborted, an error
message is generated, and the IOC restarts with the original firmware.
11. Type set configuration restore and press Enter to restore the contents of the IOC
configuration.
Upgrading Single IOCs
To upgrade the software in a single IOC, use the procedure in this section. Outputs from the
TimeCreator 1000 are interrupted for up to 30 minutes until the upgraded IOC enters the Locked
mode.
1. Login at the Admin level.
Page 6 097-93100-02 Revision H – February 2010
2. Type set configuration backup ioc and press Enter to save the contents of the IOC
configuration.
3. Type
upgrade ioc1 <filename> <ftp-server> ftp auto-reboot and press Enter.
(For example,
upgrade ioc1 ver2.bin 192.168.5.64 ftp auto-reboot) The user is
then prompted for the user name and password for the server and the new software is
loaded into the IOC.
Note: The system will FTP the file from the specified FTP server and then upgrade the
module.
Note: Firmware upgrades will not be implemented unless the IOC is rebooted, whether
manually or with the auto-reboot command.
4. The new software is loaded into the IOC, the IOC is rebooted, and it then enters Warm-up
mode for up to 30 minutes.
Caution: For non-redundant IOC modules, the IOC will restart and the outputs will be
interrupted for approximately 30 minutes.
5. Type set configuration restore ioc and press Enter to restore the contents of the IOC
configuration.
