4900M connection to HP Virtual Connect Flex 10 - Not Working

HP Virtual Connect Flex-10

Update: The configuration on the HP Virtual Connect side was incorrect. Once the server team reconfigured their side, all was good.

Today I am posting something I submitted to supportforums.cisco.com.

The customer has consultants configuring the HP side of things. I was asked to configure a Catalyst 4900M to work with the HP Virtual Connect Flex-10. From the Cisco side, this is not complex.

Tomorrow I am going onsite. I will open a TAC case on the way and sit beside the server guys.

4900M connection to HP Virtual Connect Flex 10

I'm Trying to connect a HP-C7000 blade server with a Virtual Connect Flex 10 connection with 10Gb links to a Catalyst 4900M. I have no control of the HP side.

From the HP guide, we are following "HP Virtual Connect Ethernet Cookbook" "Scenario 1:5 - VLAN Tagging (802.1q) with Shared Uplink Set (SUS) with Link Aggregation using LACP (802.3ad) - VMware ESX"

On the 4900M, LLDP sees the Virtual Connect and LCAP up with 2 active links.

Show interface on Ten1/1, Ten1/2, Port-Channel 1 shows 0 packets input.

Basically, we can not get any packets from the HP Server/VMware server side through the Catalyst 4900.

IOS version: 12.2(54)SG

Switch ports are as follows:
