The total number of ports in which IGMP snooping is active (sum of the ports within IGMP snooping-enabled VLANs). For example, if IGMP snooping is enabled in 16 VLANs, each of which has 10 ports, there will be 160 IGMP snooping-enabled ports.
- #2
-
The maximum number of registered entries, including multicast addresses for control packets used by the routing protocols. Such entries are registered on receipt of a group participation request for a control packet. When a VLAN uses multiple routing protocols concurrently, the number of registered entries corresponds to the number of multicast addresses used by the control packet of the routing protocols concerned.
- #3
-
This is the sum of the multicast MAC addresses learned by VLAN.
