Viewing the MAC Synchronization Between VLT Peers
You can use the following commands to verify the MAC synchronization between VLT peers:
VLT-10-PEER-1#show mac-address-table count MAC Entries for all vlans : Dynamic Address Count : 1007 Static Address (User-defined) Count : 1 Sticky Address Count : 0 Total Synced Mac from Peer(N): 503 Total MAC Addresses in Use: 1008 VLT-10-PEER-1#show vlt counter mac Total MAC VLT counters ---------------------- L2 Total MAC-Address Count: 1007 VLT-10-PEER-1#show mac-address-table Codes: *N - VLT Peer Synced MAC VlanId Mac Address Type Interface State 10 00:00:4c:54:8b:f6 Dynamic Po 11 Active 10 00:01:e8:95:ec:97 Dynamic Po 33 Active 10 00:01:e8:b3:ba:47 Dynamic Po 33 Active 30 a0:00:a1:00:00:01 Dynamic Po 11 Active 30 a0:00:a1:00:00:02 Dynamic Po 11 Active 30 a0:00:a1:00:00:03 Dynamic Po 11 Active 30 a0:00:a1:00:00:04 Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:05 Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:06 Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:07 Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:08 Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:09 Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:0a Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:0b Dynamic (N) Po 11 Active 30 a0:00:a1:00:00:0c Dynamic Po 11 Active VLT-10-PEER-2#show vlt statistics mac VLT MAC Statistics -------------------- L2 Info Pkts sent:0, L2 Mac-sync Pkts Sent:7 L2 Info Pkts Rcvd:0, L2 Mac-sync Pkts Rcvd:9 L2 Reg Request sent:0 L2 Reg Request rcvd:0 L2 Reg Response sent:0 L2 Reg Response rcvd:0
Note that the MAC address synchronized by a VLT peer is differentiated with an (N) flag in the example output.
