Im having a big problem in our network, im almost sure, the problem is the switch.

I believe the problem is on the VLAN or somethingm could someone analize this for us?

The problem is that our firewall is not reaching or reach only sometimes the trust network, it is a problem that come and goes.. sometimes, from the firewall i can ping the address 192.168.12.30, and sometime i cant...  we tried everything, the last resort is the problem on the switch..

There's not NEARLY enough information here.

Where's the firewall?

Where is 192.168.12.30?

Where is the routing being done at?

Why don't you think the problem is with the firewall?

firewall is SSG140 on interface 1 interface 23,

192.168.12.30 is the VMWARE MANAGEMENT

Routing.. good question, nowhere, on the ssg140, which is also the firewall maybe.

the SSG is a secure gateway which also does routing.

You have the ports on the switch where the firewall connects configured as a trunk.

I would disconnect one of the links from the firewall and see if the problem persists.  If it does, reconnect that link and remove the other one then check again.  If this solves the problem you should look at the configuration of the firewall to see if it does active/active load-balancing across the NICs or not.

I'm guessing this is a mismatch between the config on the firewall and the switch.

Craig, firewall pings switch and switch pings firewall, switch do not ping virtual machines...

I tried to disconnect ports 1 and then 23, problem persisted.

i am start considering hardware failure on the switch.

Any other ideas?

Just disconnected one of ports and problem is gone, still need to found out WHY the problem is occuring, probably a fault cable or switch port.
