capturing lwapp data frames

Unanswered Question
Nov 3rd, 2008

I have trouble capturing lwapp data frames. I have AP on port 1, i have instructed my switch (3750) to monitor this port and send it to a available port on the same switch (no stacking). On the second port , i connect my sniffer. I see lwapp control frames (RRM,ect) , keepalives and 802.11 assoc frames, however, i do not see the encapsulated data frames. I need to see those to know that my end to end qos tagging is working properly.

traces with wireshark.

Any ideas ?

I have this problem too.

Nope, standard lwapp deployment.

In the meantime i have found a workaround using a hub. Attach the hub on the switch, then the ap on the hub and presto you can see all packets.

Seems to be a limitation of monitor ...

Anyone can confirm it ?
