WAAS 4.1.1.c problems

[elliottreyes]

Does anyone have as many problems as I do with these WAAS appliances. It seems as if I have a problem every week with these things.

This sounds to me that the core device is not intercepting the traffic. Are you using inline or WCCP for redirecting the traffic to WAE? If you are using inline card did you ensure that the inline interface is not in shutdown mode or you do not have 'no inline vlan all' command ( 'no inline vlan all' under inline interface means that do not intercept any traffic ).

In essence, the core WAE is not intercepting the traffic for some reason. So, you must ensure that the redirection technique you use properly redirects the traffic to WAE.

If WAE doesn't intercept the traffic then you will not see any 'connections' under WAE->Monitor->Connection Statistics.

Traffic was being redirected as expected before upgrading the code. No changes made except WAE code upgrade. "sh wccp routers" on core WAE does not have an entry for "Router(s) seeing this Wide Area Engine" but does list the IP of the router for "Routers not seeing" this wae. sho ip wccp 61 det and 62 det on the router indicates the "State: NOT useable". Looks like WCCP has stopped working on the router. NO changes were made to the router.

From which version on WAE you upgraded to 4.1.3? I have done several times from 4.0.19 and 4.1.1x to 4.1.3 and I have never faced this problem because of upgrade.

Are you able to ping from WAE to router and vice versa?

ICMP working properly in both directions. router sho ver:

Now that I know you are using 38xx router as your traffic redirecting router could you tell me what is the redirect, egress & return method configured on the WAE? Perhaps, WCCP specific config from WAE might help to isolate the issue.

The WAE is configured for 'L2 Return'. I am not sure whether WAE is L2 adjacent to 3825 router. So, can you can change the 'Return method to GRE'?.

Basically, remove the 'l2-return' from ' wccp tcp-promiscuous router-list-num 8 l2-redirect assign-method-strict l2-return ' command on your WAE.

I've bounced router. Removed WCCP from router, added it back in, no change in WCCP state.

Update:

Changed router code to 12.4(25). 4.1.1c on WAE and WCCP worked.

Changed WAE code to 4.1.1d. WCCP worked. Went to 4.1.3 (just to see), WCCP failed. Changed back to 4.1.1d, WCCP worked.

A TAC case was opened for this by another person for this WAE. TAC recomended changes on the router (bounce, turn off/on WCCP). Neither had WCCP working with the 4.1.3 WAE code.
