Resolved Caveats—Cisco IOS Release 12.0(8)

• CSCdm86777

A Cisco 7200 series router might not switch packets when crypto map is configured. This situation

occurs when you enable Cisco Express Forwarding (CEF) switching. Symptoms might include a

connection activity display of twice the normal number of encrypted and decrypted packets than

for the peer router when you enter the show crypto cisco connections privileged EXEC command.

There is no workaround.

• CSCdm94728

Traffic to a Versatile Interface Processor (VIP) might not be routed properly on a Cisco 7500 or

7200 series router that is running Cisco IOS Release 10.3(6.3) if the destination link is encrypted

using Cisco Encryption Technology (CET). There is no workaround.

• CSCdp00331

IP Security (IPSec) might not function properly if you are running Cisco IOS Release 12.0(6.3)T.

There is no workaround.

• CSCdp05176

Priority queueing might not function properly with a protocol type-code access list on Cisco 2600

series routers. There is no workaround.

• CSCdp05948

Attributes 197 and 255 in the RADIUS accounting stop record are recorded as “0” on a Cisco 2600

series routers and Cisco 3600 series routers that are running Cisco IOS Release 12.0(5)T1. There

is no workaround.

• CSCdp07039

Cisco 1700 series routers and Cisco 2600 series routers that are running Cisco IOS Release 12.05 T

cannot start ISAKMPA SA using the rsa-encr authentication method. The debug output reports that

“Hash payload is incorrect!” There is no workaround.

• CSCdp07404

You might receive LINK-2-INVTULN traceback messages on Asynchronous Security Protocol

(ASP) interfaces. This situation can occur on any Cisco router. There is no workaround.

• CSCdp07476

When you enable bridging on a Fast EtherChannel (FEC), the host functionality might not work

properly, but bridging functionality is not affected. There is no workaround.

• CSCdp13469

Distributed Cisco Express Forwarding (dCEF) might not function properly on PA-T3 High-Speed

Serial Interfaces (HSSI) port adapters, and traffic on the interface is not switched by distributed

switching after a large number of interface reset events occur. There is no workaround.

• CSCdp16515

A Cisco router will reload if IP Security (IPSec) is enabled with fast switching on links that use

PPP encapsulation with PPP compression. There is no workaround.

• CSCdp21248

If distributed Cisco Express Forwarding (dCEF) and Cisco Encryption Technology (CET) are

enabled on a Versatile Interface Processor (VIP), encrypted traffic from the VIP to a non-VIP

interface will be process switched. There is no workaround.
