Information about Static MAC Address Support on Service
Instances
Static MAC address configuration on service instances eliminates the need for MAC address learning, which
is required for traffic forwarding. In the upstream direction, without MAC address learning, MAC address
table resources can be conserved and network resources optimized.
When a bridge domain ID is either changed or deleted for a service instance, all static MAC addresses are
removed.
When a service instance is deleted, all static MAC addresses on that pseudoport are removed.
Benefits of Static MAC Address Support on Service Instances
• Facilitates optimization of network resources
• Conserves MAC table resources when used for upstream traffic
