I setup a new VLAN with ID 153 in vSphere for my ESX4 server. The VLAN is setup for virtual machines and then I added a new NIC to the VM I want to be able to access the VM. The NIC is added to VLAN 153, but yet I am unable to ping the VLAN .1 IP that is setup on our Cisco 3750.
The IP is properly setup on the Cisco 3750 because I'm able to ping the interface IP from other machines on the network. I'm guessing there must be an issue with the cabling.
