Cisco Cisco IOS Software Release 12.2(4)XL Release Notes

The squeeze command, which is used to erase all files marked for deletion on a Flash file system, is now

available on Cisco 2600 and Cisco 3600 series routers.

In Cisco IOS Release 12.2(2), the range of the output attenuation command for voice ports has changed 
from 0-14 to -6-14.

Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most 
serious caveats; severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only 
select severity 3 caveats are included in the caveats document.

This section contains only open and resolved caveats for the current Cisco IOS maintenance release.

All caveats in Cisco IOS Release 12.2 T are also in Cisco IOS Release 12.2(4) XL6. 

For information on caveats in Cisco IOS Release 12.2 T, see Caveats for Cisco IOS 
Release 12.2 T, which lists severity 1 and 2 caveats and select severity 3 caveats and is located on 
Cisco.com and the Documentation CD-ROM.

All the caveats listed in this section are resolved in Cisco IOS Release 12.2(4) XL6. This section 
describes only severity 1 and 2 caveats and select severity 3 caveats.

On G.SHDSL, the upstream and downstream data rates do not match with auto mode, hence RADSL 
feature works only for limited line rates.

Workaround: There is no workaround.
