Cisco IP Telephony Troubleshooting Guide for Cisco CallManager Release 3.0(1)

Look for a line with “config” or “CFG” and use the corresponding number as the taskID for the
next line. For example, for the Digital Access WS-X6624 gateway, the command to dump the
DHCP information is:
TaskID: 6
Cmd: show dhcp
The TFTP server IP address is then clearly shown. If it is not correct, verify that your DHCP
options and other information it provides are correct.
Once the TFTP address is correct, the next step would be to ensure that the gateway is getting its
configuration file from the TFTP server. If you see the following in the tracy output, your TFTP
service may not be working correctly or the gateway might not be configured on the
Cisco CallManager:
00:09:05.620 (CFG) Requesting SAA00107B0013DE.cnf File From TFTP Server
00:09:18.620 (CFG) TFTP Error: Timeout Awaiting Server Response for .cnf File!
The gateway will attempt to connect to the same IP address as the TFTP server if it does not get
a configuration file. This is fine unless you are in a clustered environment in which the gateway
needs to receive its list of redundant Cisco CallManagers. If the card is not getting its TFTP
information correctly, check the TFTP service on the Cisco CallManager and make sure it is
running. Also, check the TFTP trace on the Cisco CallManager as well.
Another common problem is that the gateway is not configured correctly on the
Cisco CallManager. A typical error is entering and incorrect MAC address for the gateway. If
this is the case, for a Catalyst 6000 gateway, you will probably get the following messages on the
NMP console every two minutes:
2000 Apr 14 19:24:08 %SYS-4-MODHPRESET:Host process (860) 7/1 got reset asynchronously
2000 Apr 14 19:26:05 %SYS-4-MODHPRESET:Host process (860) 7/1 got reset asynchronously
2000 Apr 14 19:28:02 %SYS-4-MODHPRESET:Host process (860) 7/1 got reset asynchronously
This is what the tracy output would look like if the gateway is not in the Cisco CallManager
database:
