Cisco Cisco IOS Software Release 12.2(2)XQ Guide De Dépannage

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most 
serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these 
three severity levels.

Caveats in Cisco IOS Releases 12.2 and 12.2 T are also in Cisco IOS “special” releases (such as 
12.2(2)XQ1). For information on caveats in Cisco IOS Release 12.2, see Caveats for Cisco IOS  
Release 12.2. For information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS  
Release 12.2 T. These two documents list severity 1 and 2 caveats and are located on CCO and the 
Documentation CD-ROM. 

If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity 
for any release. To reach Bug Navigator II, Login to Cisco.com and click Software Center: 
Cisco IOS Software: Cisco Bugtool Navigator II. Another option is to go directly to

This section describes possibly unexpected behavior by software Release 12.2(2)XQ1.

When running MLPPP/LFI and changing parameters for an ATM interface (such as encapsulation or 
vbr-rt), the virtual-access interface might go down and not come back up.

Workaround:

To bring up the virtual-access again under these circumstances, re-issue the command protocol ppp 
Virtual-Template1 for the ATM interface.
