Layer-2 Traffic in VLT Domains In a VLT domain, the MAC address of any host connected to the VLT peers is synchronized between the VLT nodes. In the following example, VLAN 10 is spanned across three VLT domains. Figure 138. Layer-2 Traffic in VLT Domains If Host 1 from a VLT domain sends a frame to Host 2 in another VLT domain, the frame can use any link shown to reach Host 2. MAC synchronization between VLT peers handles the traffic flow even if it is hashed and forwarded through the other member of the portchannel. 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 Virtual Link Trunking (VLT) 989
