VLAN cannot communicate across

Hi,

We have two cisco switches. 1x3560 & 1x3500. I have setup the VLAN and trunk 2xGIG to etherchannel but from vlan 40 I am not able to ping any server in VLAN 32. Thanks

From the 3560 can you post the outputs of

1) sh int trunk

2) sh etherchannel summary

Jon

I would post a show vlan from both switches also. I must be missing something as I don't see any kind of etherchannel commands on the 3500 side so it couldn't work if you have a channel setup on 1 side and not the other.

Problem is solved. The problem was the unix machines doesn't have the default gateway to return the traffic. Thanks
