Jun 14 01:58:46 APDC4R10-NWAE02 wccp: %WAAS-WCCP-5-500024: Removing router 0.0.0.0 from router table.
Issue is sporadic in nature, SR has been open and TAC has given action plan when issue come again but, i am sure same issue happened earlier somewhere and solution must be in place rather reactive approch to wait for issue to come.
Appreciate if any one has already know the solution on this.
Because your WCCP tunnel is going randomly down, I believe this is either a design issue or a WCCP configuration problem.
Because is randomly happening is hard to run captures at the same time of failure but we can still review the captures when it is actually working.
There are four WCCP V2 messages:
* Here I AM
* I See You
* Redirect Assign
* Removal Query
Each WCCP message comprises a WCCP Message Header followed by a number of message components, for example if the length value or any component header is not set as expected one might expect to see WCCP errors.
here are Nexus WCCP compatibilities notes:
-Assignment methods supports only mask assisments. this is the same as saying that the Nexus and the WAAS device are L2 connected and should be properly configure to run mask assigments .. not hash.
-In addition any packets being " bypass return" should go via L2.
-Packet egress redirection goes via IP forwarding and negotiated L2 return as well.
-WCCP GRE return is not supported, WCCP GRE redirection is not supported
It will be nice if you upgrade to a newer WAAS version you're about 30 versions away from the latest one, there have been many open/fix caveats for WCCP/WAAS previous codes, in addition to the enhacements you're missing.
