- port-channel channel-number - Displays MAC address table information for a port-channel interface, from 1 to 128. • static - (Optional) Displays static MAC address table entries only. • vlan vlan-id - (Optional) Displays VLAN information only, from 1 to 4093. Default Command Mode Usage Information Example (Address) Not configured EXEC The network device maintains static MAC address entries saved in the startup configuration file, and reboots and deletes dynamic entries.

You can configure Multiple Spanning-Tree Instances (MSTIs) and map multiple VLANs to one spanning-tree instance to reduce the total number of instances. RPVST+ allows a spanning-tree instance for each VLAN. This 1:1 approach is not suitable if you have multiple VLANs - each spanning-tree instance costs bandwidth and processing resources. When you enable MST, all ports in Layer 2 (L2) mode participate in MST. OS10 only supports one MST region. Achieve load balancing using the MST protocol (MSTP). When you map three VLANs to two multiple spanning tree instances (MSTIs), VLAN 100 traffic takes a different path than VLAN 200 and 300 traffic. 316 Layer 2
