WCCP load balancing packet redirection with more than two gateways


I am trying to bring up a third gateway using WCCP load balancing.  I currently have two gateways using WCCP and working fine.

When I bring the third gateway online and enable WCCP things start to go wrong.  It appears, and I am not completely sure about this, but it appears that the third gateway or even all of the gateways stop working over WCCP.  Disabling the third gateway solves the issues and all is back to normal.

Working switch config:

ip wccp source-interface Vlan877

ip wccp 51 redirect-list wccp accelerated


interface Vlan877

ip address


interface GigabitEthernet0/1

description Lan - 4507

no switchport

ip address

ip wccp 51 redirect in

mls qos trust dscp



Extended IP access list wccp

    10 permit tcp any eq www 443 (302 matches)

    20 permit tcp any eq www 443 (540 matches)

    30 permit tcp any eq www 443

    40 permit tcp any eq www 443


In the MWG's I have the following config set for WCCP.

Serivce ID


WCCP Router :

Ports to be redirected: 80,443

Proxy listener IP address: (IP ADDRESS of each MWG respectively), 67

Proxy listener port: 9090 (Yes the proxy is listening on

Assign by mask (This is what my switch supports)

Input for load distribution: Source IP mask  - 0x15     and      Destination IP mask - 0x15

Forwarding method: L2 (This is what my switch supports)

L2 Redirect target: eth0

Magic:  -1

To recap, I have two MWG's running with this config, but connecting the third one via WCCP to the switch kills most if not all of the WCCP packet redirection.

Any ideas?
