Hi,
I have a pair of Cisco 4507 switches in VSS mode. An server (10.4.1.166) using Microsoft NLB MAC address (03bf.0a04.01a6) is connected to VSS Node 1 on port Gi1/6/43. The following is configured on the switch.
arp 10.4.1.166 03bf.0a04.01a6 ARPA
mac address-table static 03bf.0a04.01a6 vlan 31 interface Gi1/6/43
The second command appears differently in running-config but looks good in mac-address-table:
# show running-config | inc mac address
mac address-table static 03bf.0a04.01a6 vlan 31 interface Gi6/43
# show mac address static | inc 01a6
31 03bf.0a04.01a6 static Gi1/6/43
Now, from a PC I can ping the VIP address 10.4.1.166 when connected to VSS Node 1 or any other switch connecting to VSS Node1. If the PC attachment is to VSS Node 2 directly or indirectly, then the ping times out. Doing the same for all the rest of servers not using Microsoft NLB but connected to Node 1 only, is successful from anywhere.
Why is the traffic not traversing the the VSL link i.e. PC -> VSS Node 2 -> VSL -> VSS Node1 -> Server.
Thanks,
Rick.
