Cisco Cisco IOS Software Release 12.2(2)XT

CSCin02687

Symptom:

When using the Cisco 7200 series router as a Survivable Remote Site Telephony (SRST) and IOS 
telephony service router and making more than 30 three-party conference calls, the router crashes. 
The tracebacks point to the fast-ethernet interface that is being used to connect the router to the IP 
phones or rather the IP phone simulator.

Workaround:

Restrict the number of three-party conference calls.

CSCdv62649

Symptom:

The command ip tacacs source-interface does not work properly. 

Workaround:

If configured to use loopback interface for tacacs packets, the router may still use the interface 
address.

CSCdw08182

Symptom:

The VWIC installed in NM-1FE2W appears in show diag response but not in the configuration.

The router is recognizing that it has a VWIC-1MFT-T1 in a NM-1FE2W in the show diag. The 
problem is that the T1 controller doesn't appear in the configuration. The FastEthernet is present. 

There is no work-around.

Symptom:

A call to a busy FXS port produces an incorrect release cause code. Calls may receive a "no route 
to destination" message and an incorrect clearing cause code (instead of a user busy cause code) 
when calls are placed to a Foreign Exchange Station (FXS) on a busy interface. Depending on the 
equipment that is used, the caller may receive a "number unobtainable" message or fast busy tones 
instead of a busy tone when this condition occurs. 

Workaround: 

Add a huntstop on the dial peer that is assigned to the FXS interface.

CSCdw38767

Symptom:

Some ports on the NM-16ESW / NMD-36-ESW may not be assigned MAC addresses properly. 

Conditions:

This occurs when the last digit of the base MAC address burnt in the NM cookie is in the range 0xF0- 
0xFF for NM-16ESW and range 0xDA-0xFF for NMD-36-ESW.

Workaround:

None.
