Nexus 3K Issue with StringRay VIP

Hello,

I have a Nexus 3K at my core.  I have a DMZ connected to my ASA with a StringRay LB.  When I connect the ASA to the Nexus, non of the VIP's for StringRay are working, everything else works fine.

 

I've noticed that the VIP of the stringRay uses a multcast MAC address:

 

        dmz 192.8.6.81 0100.5e65.0101
        dmz 192.8.6.82 0100.5e65.0102

 

I've tried to add a static entry but I get:

 

MAIN61-AUG-SRVR-N3K2(config)# mac address-table static 0100.5e65.0101 vlan 6 interface port-channel 10 
mac address-table static 0100.5e65.0102 vlan 6 interface port-channel 10 
ERROR: mac address is an ip multicast mac
MAIN61-AUG-SRVR-N3K2(config)# mac address-table static 0100.5e65.0102 vlan 6 interface port-channel 10 
ERROR: mac address is an ip multicast mac

 

I am assuming that this multicast MAC address is causing the issue on the Nexus.  We have a 3750 currently and do not have the issue.

 

Does anyone know how to get around this.  I've looked at a Microsoft 7K article - http://www.cisco.com/c/en/us/support/docs/ip/multicast/116150-configure-Nexus7000-00.html#anc6 but I don't have the command available in the 3K.

 

Thanks
