Cisco 3750--Can't ping

I have a virtual connect connected to Cisco Catalyst 3750 as an access port or un-tag port and am able to ping fine my VC from one of the workstations part of the same VLAN. However, I created an LACP link between Cisco 3750 and Virtual Connect (un-tag or access port), and now I can't ping my VC. I see port-channel is up and below is my Cisco Configuration.

interface Port-channel1
no ip address


interface GigabitEthernet2/0/17
no ip address

no mdix auto

Re: Cisco 3750--Can't ping

Hopefully you are not trying to ping from the 3750 because it doesn't have an ip address on the port channel. If you are trying to ping from the workstation, are they on the same VLAN/Subnet? For testing, assign an address on the port channel interface and try to ping that from your WS and VC
