I hate asking this question because I can do it across the entire LAN but not on a single switch:
I have a 3750 24T switch with the IP Services image.
I have 4 subnets I need to setup so all can talk to the other but it just ain't happening.
vlan 400
10.110.1.254
vlan 515
10.130.200.254
(These , vlan 515 & 516 are Virtual Machines on an ESX host that has 1 trunk port. The ESX host IP is 10.110.1.10 and will not respond if its on a trunked port)
vlan 516
10.130.201.254
vlan 800
10.110.5.1
(switch management)
I have tried OSPF, EIGRP and Static routes. Could someone please hit me with the DUH stick, I am stumped!
Thanks,
Chad

Chad,
Look at this link.

It may be the way you have configured your trunk port.
Your config should be something like this:-
interface FastEthernet 0/1
description *** TO ESX HOST***
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 400,515,516
switchport mode trunk
switchport nonegotiate
no ip address
spanning-tree portfast trunk

Make sure that you have ip routing enabled...

If it is a single switch you don't to run any routing protocols. As John noted make sure IP routing is enabled. But then again you can't turn on any protocols without enabling IP routing. Check anyway.
You say
(These , vlan 515 & 516 are Virtual Machines on an ESX host that has 1 trunk port. The ESX host IP is 10.110.1.10 and will not respond if its on a trunked port)
You are referring to vlan 515 and 516, but the IP 10.110.1.10 is part of vlan 400. So, what vlans are working and which once are not?
BTW, if you trunk a link that is connected to an ESXi server, you need to add the vlan tag to the ESXi server also.
Does it work if you make it an access port?
Are the physical ports connected to these vlans in up and up mode?
Are the vlan interfaces in up and up mode
Can you clarify?

Thanks for the replies!
Ip routing is on.
I had port 23 & 24 setup as dot1q trunk ports, which may have been my problem, esx server is 10.110.1.10 and it would not ping while on the trunk. Switching to an access port fixed that. All other ports on switch are on vlan 400.
