After I put the FWSM Module, version 3.1.4 in my Switch 6509 and start to separate the VLAN with CCM and IPCC Servers and the VLAN with the clients, I noticed that a few conversations do not complete. I take a look in the following command
FWSM/interno# sh asp drop frame
TCP failed 3 way handshake 1
TCP RST/FIN out of order 9
TCP packet buffer full 1043
TCP DUP and has been ACKed 11631
and I think the buffer full can be the reason.
Is there any way to adjust the queue in FWSM Module ?
Unfortunately, there is no way to adjust the TCP packet queue on the FWSM.
If the TCP packet buffer full counter is incrementing at a decent rate, it means you have a lot of out-of-order packets on connections that are being proxied by the FWSM (most likely your voice traffic). The only way to fix things is to figure out why the packets are getting out-of-order.
