WAAS DISCOVERS NO PEER

[CSCO11117246]

Hello,

I have two waas boxe, one in the data centre as teh core and the other as the edge. They both register with the central manager and they both see traffic but everything is passthrough as no policies are applied. They are in the same device group so that is not the problem. The issue is the two devices dont peer with each other. What could be the problem as the configs on the waes are standard and have been used successfully before in pervious deployments. Could it be one of the boxes have a problem and how can i check?

Do you have any firewalls in between the edges and cores? The fact that your connections are not seeing any peers and some blacklisting may show that something is blocking autodiscovery, possibly due to the TCP options during the syn/syn-ack.

Another thing to look at is if you are intercepting on all of your WAN egress points? Possibly some asynchronise routes where you are not doing interception? Doing traceroutes from the client and server side will assist in tracking something like that down.

The command in 4.0 is "sh tfo auto-discovery list". Another good on is to do "edge-fe1#sh tfo auto-discovery blacklist" to see if you are getting a lot of hits on connections that are getting dumped by firewalls or other deep packet inspection technology.
