wae does not see the neighbour

Hello!

Is available 2 wae-612 (accelerator) and 1 wae-512 (CM)

It is impossible to start in any way them in work.

The scheme:

net1 - freebsd1 - internet - freebsd2 - net2

.........wae1..................wae2

the Traffic on wae from freebsd is transferred through ipfw.

In logs wae2:

java: %WAAS-CMS-5-700001: ce(DataFeedPoll): update dataserver lastUpdateTime to: 1211867708092 status 0

In wae1 it is not present.

Prompt in what I was mistaken.

Re: wae does not see the neighbour

Ad,

The counter:

No peer or asymmetric route: 3232

indicates that the WAE is either 1) not seeing the SYN-ACK for the connection, or 2) the WAE is seeing the SYN-ACK, but it does not contain auto-negotiation options.

Re: wae does not see the neighbour

How it is possible to check up it and to repair?

Re: wae does not see the neighbour

I would first verify (via traceroute, etc.) that traffic is traversing paths on both sides of the WAN that the WAEs are on.

Next you can take a packet capture on the WAE (using tcpdump) to verify that the WAE does indeed see traffic in both directions.

Re: wae does not see the neighbour

Hi.

traceroute from both WAE:

WAE-1#traceroute 192.168.170.141

traceroute to 192.168.170.141 (192.168.170.141), 30 hops max, 38 byte packets

1 192.168.40.110 (192.168.40.110) 0.857 ms 0.601 ms 0.760 ms

2 192.168.167.66 (192.168.167.66) 64.795 ms 63.484 ms 63.462 ms

3 192.168.170.141 (192.168.170.141) 64.988 ms 64.300 ms 73.255 ms

WAE-1#

WAE-2#traceroute 192.168.40.109

traceroute to 192.168.40.109 (192.168.40.109), 30 hops max, 38 byte packets

1 192.168.170.142 (192.168.170.142) 0.119 ms 0.095 ms 0.137 ms

2 192.168.167.65 (192.168.167.65) 57.637 ms 61.645 ms 58.478 ms

3 192.168.40.109 (192.168.40.109) 66.764 ms 61.275 ms 70.447 ms

WAE-2#

On tcpdump client packets are visible, packets from WAE it is not visible, only from Central-manager on 443 port it is visible.

Re: wae does not see the neighbour

The WAE will preserve the source/destination IP addresses from the original packets. If you are seeing packets on the WAE, then that's an indication that redirection is working properly.

Next we need to find out why auto-discovery is failing. You can use the debug 'debug tfo conn auto' for this. If there is a significant amount of traffic going through the WAEs, you can use an access list to restrict which traffic is subject to the debug.
