Problems with MS NLB over vPC using N5K and 6509E

Justin DeVaughn

I've attached a visio diagram of the configuration for reference.

I'm having two problems:

1.  I cannot ping the VIP 10.10.1.1 on the MS NLB servers from other subnets on their ODD numbered IPs.  For instance 192.168.1.1 cannot ping the VIP while 192.168.1.2 can ping the VIP.

2.  N5K-1 cannot ping the VIP while N5K-2 can ping the VIP.

I  have the requisite ARP 10.10.1.1 (insert multicast mac here) ARPA command on the 6509E

I  have the Mac address-table static (insert multicast mac here) vlan 10 interface (list interfaces over to N5K e.g...TenGigabitEthernet1/1)

Every connection is vPC'd in the same configuration as below: 6509E --> N5K's --> ESXi hosts

I'm not sure where to begin troubleshooting!  These are CAS servers so they are affecting e-mail.  any help is definitely appreciated!

Below is the configuration for the N5K's:

interface port-channel1

  switchport mode trunk

  vpc 1

  switchport trunk native vlan 5

  switchport trunk allowed vlan 1,5-6,10-12,57-58

interface port-channel2
