WAAS - WCCP 61 and 62 on same interface

Unanswered Question
Feb 15th, 2010

We have WCCP 61 and 62 options on the LAN facing interface, 61outbound and 62 inbound. Does anyone see any performance issue with having them on the same interface for remote branches only? Also, we get better load balancing when reversing the direction for 61 and 62, any ideas why? I always thought 61 inbound would load balance based on the source IP address, but by doing it with 61 outbound, we're getting better load balancing between the 2 WAEs. Is it because we're running them both on the same interface?

This what we use for our WCCP traffic.

We created a new VLAN for the WCCP traffic.

ip wccp version 2

ip wccp 61

ip wccp 62


ip wccp 61 redirect in


ip wccp 62 redirect in


ip wccp redirect exclude in

With outbound redirection you need to configure 'ip wccp redirect exclude in' command on the L3 interface connected to the WAEs.

61 will hash on Src IP and 62 on destination IP. With '62 redirect in' on LAN interface, traffic based on destination address will be redirected to WAE.
So if same sets of Clients go to multiple destination then since hashing is being done based on dest address the load distribution might be different
than if its done based on Source IP (service 61).

Inbound redirection is generally preferred over outbound redirection because the redirection is far less resource-intensive in terms of CPU utilization.

Please also have a read through WAAS wiki,

Hope this helps,

Thank you rvavale for your information, do you have documentation about services 61 and 62?
