Resolved Caveats—Cisco IOS Release 12.0(5)

• CSCdk84841

When you configure an X.25 line as a passive interface for OSPF, the line might stay in an OSPF

“down” state after a line flap, even though the line protocol is up. You can check the OSPF state in

the output of the show ip ospf interface command. As a result, this line’s network number will not

be advertised by OSPF.

Workaround: Do not to make this interface passive for OSPF.

• CSCdm02740

When an interface with ip cgmp configured is deleted, some data structures are not properly

cleared. If the interface is later recreated and no ip cgmp is configured, the router will reload.

Workaround: Configure no ip cgmp before deleting the subinterface.

• CSCdm05636

CPU utilization can be too high due to the number of NAT entries in the NAT table. There is no

workaround.

• CSCdm13956

ICMP redirects can overwhelm process switching.

Workaround: Clear IP redirect or reload the router.

• CSCdm25188

A Cisco router might reload if a badly formed h323/h225 packet is processed by NAT. There is no

workaround.

• CSCdm28898

ARP to a router fails on the serial interface when bridging is enabled after a router is reloaded. This

condition occurs with Cisco 2500 series routers running Cisco IOS Release 11.2(17) and

Release 12.0(3.7).

Workaround: Remove the IP address on serial interface and reenter it.

ISO CLNS

• CSCdm28035

If a Cisco router originates multiple link-state packets (LSPs), the fragments might not be correctly

purged from the neighboring LSPDB. The problem is only seen with “authentication;” that is, if

domain-password [xxx] is configured. There is no workaround.

Miscellaneous

• CSCdj89070

The command show crypto card on a Cisco 7500 series router does not return any information.

The command should provide output similar to the following:

Router# show crypto card 1 Crypto card in slot: 1 Tampered: No Xtracted: No Password

set: Yes DSS Key set: Yes Router#

To verify that the card is recognized by the software, use the show diag or

show crypto engine brief commands. There is no workaround.
