I'm wanting to move my ESX servers from using a Cisco 2821 with a switch module, to using a Cisco 3750g Switch (layer 3). It was working on the 2821, but I'm going to add a couple more ESX servers, so I need more ports. Both ESX servers have Intel quad port gigabit NICs. I have 4 vSwitches that each connect to one of the NICs, and these vSwitches each have a port group that is tagged with a vlan number. On the switch each port has this config:
switchport trunk encapsulation dot1q
switchport trunk native vlan 1005
switchport mode trunk
I have the VLAN's created on the switch and the IP address for the VLAN is pingable from the switch.
____________________
If I turn off the VLAN tagging and set the port to "switchport access vlan nn" it works fine; I'm able to ping the ip address of each VLAN. But this means I can only use one port group per pNIC, which isn't what I need to do. Any help would be appreciated. Thanks.

When looking at this thread: http://communities.vmware.com/message/749561#749561
Try using:
switchport trunk encap dot1q
switchport mode trunk
switchport trunk allo vla 100,200
switchport nonego

Also make sure the native vlan is different then the vlan's you are trying to pass over the link.
It was all about "switchport nonegotiate". I thought the command "switchport mode trunk" was supposed to set it to only use trunking, but on I needed the other command. Thanks alot.
