Caveats for Cisco IOS Release 12.0
78-6455-12
Miscellaneous
• CSCds41097
On a Cisco router, the Token Ring interface gets wedged after upgrading from Cisco IOS
Release 11.2 code.
Workaround: Reload the router each time the problem occurs.
• CSCds41672
Upon reloading a Cisco router that is using multiple tunnel interfaces and Cisco Encryption
Technology (CET) over Frame Relay it is possible that the router may experience only part of the
CET tunnels responding.
Workaround: Using the clear crypto connection command in global configuration will allow the
rest of the tunnels to respond.
• CSCds43080
When NMHDV+WIC-2MFT-T1 is configured to support 48 calls using a connection trunk, and the
voice activity detection (VAD) device is disabled, the trunked calls will begin to flap. There is no
workaround.
• CSCds45328
A small amount of memory will be allocated and not freed when the configuration is written to
nonvolatile memory. There is no workaround.
• CSCds49667
With distributed Cisco Express Forwarding (dCEF) enabled on an ATM subinterface, IfInOctets
will appear to be decreasing whereas show interfaces privileged EXEC command as well as
IfInPackets show increases. There is no workaround.
• CSCds51143
An E1 Continuity Test (COT) in loopback mode fails. There is no workaround.
• CSCds52655
On a Cisco 3620 router running Cisco IOS Release 12.0(6), the no ip directed-broadcast interface
configuration command is configured on all interfaces, but the router still passes the ip
directed-broadcast traffic command, and the following messages are produced:
