%IPFAST-2-PAKSTICK: Corrupted pak header for BVI1

I have recently upgraded a 1760 router with release 12.3(7)T12. Since the upgrade the router displays errors on the console.

Nov 11 12:04:02.371: %IPFAST-2-PAKSTICK: Corrupted pak header for BVI1, flags 0x8A

-Traceback= 800C5078 80B0F0AC 80B104F0 802BAF8C 802C1330 8021FC1C 802B1A3C 802B1A3C 8021FCDC 803D2B60 803D2B60 803DF474 8014474C 8013FFE8 80224728 80227F30

When I turn fast switching off, the messages dissapear.

Has anyone faced simular problems?

Re: %IPFAST-2-PAKSTICK: Corrupted pak header for BVI1

Hello,

the only software bug I could find is the following:

A Cisco router that is running fast switching (not Cisco express forwarding)

and software crypto might display the following message:

%IPFAST-2-PAKSTICK: Corrupted pak header for FastEthernet0/ 1, flags 0x80

-Traceback= 6026398C 60EA7DE4 60E83840 60E82C04 6035E464 6035E450

%IPFAST-2-PAKSTICK: Corrupted pak header for FastEthernet0/ 1, flags 0x80.

There is no workaround.

This one is actually for older (12.0) IOS versions. You might want to check if you have fast-switching (ip route-cache) configured on your router.

Also, can you post your configuration ?

Regards,

GP

Re: %IPFAST-2-PAKSTICK: Corrupted pak header for BVI1

From my initial posting you could have read that I turned fast switching off.

The router has CEF enabled globally but the "no ip route-cache" switches both fast and cef switching off. However this solves the problem, but is merely a workaround. I will try a newer software image if available and see what happens.
