Layer-2 Traffic In Vlt Domains - Dell S3048-ON Configuration Manual

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 125. 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 port-
channel.
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 :
Static Address (User-defined) Count :
Sticky Address Count :
Total Synced Mac from Peer(N):
Total MAC Addresses in Use:
VLT-10-PEER-1#show vlt counter mac
