Hi Everyone
I need help on this. I have LAN users that connect to my Core Switch i.e. Cat6500. In this Core Switch, I've configured WCCP. The Cisco IronPort is situated few hops away. However, LAN users cannot browse the Internet. Based on the troubleshooting done, the Core Switch i.e. Cat6500 is able to detect the Cisco IronPort, but in L2 mode, which is not correct.
HQ-L13-C6506-01#show ip wccp 91 detail
WCCP Cache-Engine information:
Web Cache ID: 172.20.87.30
Protocol Version: 2.0
State: NOT Usable
Redirection: L2
Packet Return: L2
Packets Redirected: 0
Connect Time: 00:00:13
Assignment: MASK
ip wccp 91 redirect-list 110
interface Vlan14
ip address 10.10.6.10 255.255.255.0
ip helper-address 10.5.32.122
ip wccp 91 redirect in
access-list 110 permit tcp any any eq www
access-list 110 permit tcp any any eq 443
Where is the problem?

Hi, from someone elses answer, you need to configure the egress method:
Re: How to configure WAAS WCCP if Layer 3 link between router and switch
You will want to review 'egress-method negotiated-return intercept-method wccp'. This will return all traffic to the router in a WCCP GRE tunnel.
(config) egress-method
Configure the WAE with an IP address that is appropriate for the Switch L3 segment and use the Switch L3 interface as the default gateway.
Configure WCCP to use GRE/GRE/HASH with egress-method GRE. GRE is cpu intensive on the router so this solution may have scalability issues.
Cheers

Hi,
The command "egress-method negotiated-return intercept-method wccp"
CLI command changes the default EMIC from IP forwarding to negotiated return. So please add this command to the configuration.
Also please refer to the WCCP integration with Cat 65K Best Practices at
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper_c11-629052.html for more information about different deployment methods.
