UUID not in Policy Engine Map

[lomonaco]

Hi guys, I'm having a lot of Total Requests for UUID not in Policy Engine Map.

Is there any to find what UUIDs the WAAS are missing ??

Here the output

show statistics accelerator epm

Hello Andre,

Probably replies comes a little bit late, but here is some explanation.

This counter does not neccessarily mean that there is some problem with WAAS/EPM engine - usually if this counter is incrementing this indicates that there is some [custom] application in the network which is using non-standard (custom) MS-RPC UUID which WAAS does not know.

We generally use EPM on WAAS to properly accelerate MAPI (Exchange) connections - so, in this MS-RPC Endpoint Mapper flow (TCP/135)  we need to "catch" TCP ports which will be later used for MAPI connections so we could accelerate them.

The only method to catch full information about those non-standard-UUID streams (client/server IP, etc) is to enable debugging for EPM accelerator engine on WAAS. Again, this should be done if there are any other visible symptoms of MAPI/EPM malfunction - this counter alone does not neccessarily indicate this.

HTH,

Amir
