Release Notes for Cisco IOS Release 12.1E on the Catalyst 6500 and Cisco 7600 Supervisor Engine and MSFC
OL-2310-11
Caveats
• Only the 4-port Gigabit Ethernet WAN module (OSM-4GE-WAN) supports Layer 3 trunks.
Configuring a subinterface on a LAN port might cause a reload. This problem is resolved in
Release 12.1(12c)E1. (CSCdx24623)
• If you configure more than 16 HSRP group numbers for different VLAN interfaces in a system with
a PFC1, the following error message is displayed:
More than 16 standby groups not supported in this platform.
This problem is resolved in Release 12.1(12c)E1. (CSCdx32496)

Open FlexWAN Module Caveats in Release 12.1(12c)E5
• During a PVC discovery test on an ATM port adapter, the MSFC hangs while trying to create a
subinterface for the PVC discovery. This problem is resolved in Release 12.1(14)E. (CSCdy71452)
• FlexWAN module crashinfo files do not propagate to the MSFC bootflash device.
Workaround: Display the FlexWAN module crashinfo filename with the dir
cwanslot_number/port_adapter_number-bootflash: command. You can copy a FlexWAN module
crashinfo file with the copy cwanslot_number/port_adapter_number-bootflash: command. This
problem is resolved in Release 12.1(14)E. (CSCdr71603)
• If you enable and disable MMLS on ATM subinterfaces with a combination of point-to-point and
multipoint subinterfaces, multicast shortcuts may not be created for multipoint connections, or in
some cases multicast traffic may fail. (CSCdr01409)
Note CSCdr01409 is not seen in later releases.
• In a system installed with a FlexWAN and a PA-A3 ATM port adapter, the ATM interface may stay
down after you enter a shutdown command followed immediately by a no shutdown command.
Workaround: After you enter the shutdown command on the interface, wait for 1 minute before
entering the no shutdown command. This problem is resolved in Release 12.1(20)E. (CSCdy23751,
CSCdw65799)
• If the cable is removed and replaced on a FlexWAN module with an ATM port adapter installed, the
line protocol shows as UP but no switched virtual circuits (SVCs) are created. This behavior occurs
if traffic is running and 200 or more SVCs have been configured.
Workaround: Enter a shutdown command followed by no shutdown command on the affected
interface. (CSCdy24309)
Note CSCdy24309 is not seen in later releases.
