Is there any performance issues with redirecting wccp 62 on an SVI of the 6500 series switch? The WAN interfaces are not layer 3 but are associated with a vlan that has an SVI configured. I will be using redirect lists for interception.

Depends on the IP addresses being intercepted. The default mask is typically fine for a /23 or /24 address range.

Clifton,


On the 6500 platform, you need to follow these recommendations to ensure WCCP redirection happens completely in hardware:


- L2 Forwarding (configured on WAE)

- Mask Assignment (configured on WAE)

- Inbound redirection (configured on 6500)

- No 'ip wccp redirect exclude in' configured (on 6500)

Thanks Zach for the info. One more question.


For mask assignment, shall I use the default settings or should I edit the mask? I have two Core WAEs.
