Cisco Cisco IOS Software Release 12.2(8)YL

This section describes unexpected behavior in Release 12.2.(8)YL.

Packet greater than 5000 bytes fails when SW compression with HW encryption is done.

Crypto console error generated when tunnel is initiated via EM module.

Broadcast address is being sent as MAC Address in the Cisco 1720, 1721 and 1750 routers when an 
Ethernet WIC is in slot 1. When there is a one-port Ethernet WIC (WIC-1E) in slot 1 and a TLV 4 
EEPROM WIC, like an ADSL WIC, in slot 0, the MAC Address of the Ethernet interface is incorrectly 
set to the broadcast address ffff.ffff.ffff. The work-around for this problem is to place the Ethernet WIC 
in slot 0 only.

IPSec does not work when set pfs group# is in the configuration. For example:

crypto ap mymap1 11 ipsec-isakmp

set peer 10.0.0.1

set security-association level per-host

set transform-set 1+5+8

set pfs group2

match address 101

The work-around for this problem is to remove set pfs group# from the configuration.

A Cisco 1700 Series router with a WIC-2AM (2-port asynchronous interface) may reload while issuing 
the ipx routing CLI. The work-around is to configure ipx routing without running traffic.

When configuring MLP, the Cisco 1720 router CPEs crash when an interface is entered into a multilink 
group. No work-around is available, but it is known that the problem will not occur when using images 
from Cisco IOS Release 12.2(4)XL.

The Cisco 1760 router crashes at bootup if both VIC-2FXO-EU abd VIC-2FXO-M3 interface cards are 
inserted. Additionally, having the VIC-2FXO-EU card inserted alone will cause a traceback at bootup. 
There is no work-around.
