WCCP: Cat6k & UDP L2-mask-Redirection

Hello,

We are using a non-cisco WCCPv2 client with L2, mask assignment with 2 groups to redirect all TCP and UDP pkts.

TCP wccp redirect-in on ingress vlan works perfectly (hw switched etc).

But when we use redirect in for the udp group, udp pkts are not redirected at all, CAT6k redirects tcp even if the tcp service group is not active/created.

Please see the attached file for more information.

Is this a known issue? Do we have a configuration problem?

Is our OS is too old? Is there a knob we can turn on (mls?) to make redirect-out policy do

hardware switching?

Please let us know. We'd really appreciate your input.

Thanks in advance.

The issue may be due to TCP redirect enabled.

Check the configuration and disable the tcp redirect.

Hi Frank,

Thanks for the reply. But we want to redirect tcp and udp at the same time using l2 redirection in hw.
