WCCPv2 Layer2 - Catalyst 6509 and BlueCoat SG

Software Version: 12.2(33)SXH2a

Problem Details: 2 units of BlueCoat web cache attached to the Catalyst 6509, perform the

WCCP layer 2 re-direct.

The setup is working fine, except the IOS version 12.2(33)SXH have bug where it cause TCAM

table full when WCCP L2 perform ingress.

Advice to upgrade to 12.2(33)SXH2a. After upgrade to SXH2a, the primary BC attached to

switch 1 remain working with WCCP L2, but the secondary BC attached to switch 2, the WCCP

Layer cannot be up.

We swap the BC1 attached to switch 2 and BC2 attached to switch 1, the BC2 & Switch 1 WCCP

L2 work fine, but BC1 & switch 2 the WCCP L2 cannot be up and running. Therefore I had

rule out the possibility of BC2 is having config/hw error.

Debug ip wccp event on switch , we can see one weird message "WCCP-EVNT:D09: Here_I_Am

packet from 122.255.99.36 w/bad fwd method L2, received indirectly via Vlan2 "

What is message mean here ? What to do with Vlan 2?

Below are full debug capture.
