This allows end stations that are sources of frames destined for a Group to suppress the transmission of such frames if their registered Group membership and Group service requirement information indicates that there are no valid recipients of those frames reachable via the networks to which they are attached. This end system behavior (known as source pruning) allows MAC service users transmitting MAC frames destined for a number of groups to avoid unnecessary flooding of traffic in the local network when there are no group members registered to receive traffic. MRP Configuration Example The following example configures an MRP switch. 1 Create VLAN 2. This VLAN is used to carry the MSRP traffic. console#config console(config)#vlan 2 console(config-vlan2)#exit 2 Configure two CoS queues for minimum latency, with CoS queue 3 receiving a guarantee of 10% of the scheduler and CoS queue 4 receiving a guarantee of 15% of the scheduler. console(config)#cos-queue min-bandwidth 0 0 0 10 15 0 0 3 Configure CoS queues 3 and 4 as strict priority queues. This means that CoS queue 4 packets will be scheduled for transmission first, with up to 15% of the scheduler slots. CoS queue 3 packets will be scheduled next, with up to 10% of the scheduler slots, and then all other packets will be scheduled fairly with the remaining scheduler slots. console(config)#cos-queue strict 3 4 4 Configure interfaces Te1/0/1-4 as trunk ports and enable them for MVRP and MMRP. console(config)#interface range Te1/0/1-4 console(config-if)#switchport mode trunk console(config-if)#mvrp console(config-if)#mmrp console(config-if)#exit 5 Globally enable MVRP and MMRP and enable the periodic state machines to purge registrations periodically. console(config)#mvrp global 1640 Multiple Registration Protocol
