swIGMPPortMap
Module: COMPAQ-L2MGMT-MIB
OID (symbolic): COMPAQ-L2MGMT-MIB::swIGMPPortMap
OID (numeric): 1.3.6.1.4.1.232.161.3.2.3.7.1.4
Node type: OBJECT-TYPE
Type: PortList
Access: read-only
Description: This object indicates which ports are belonged to the same multicast group, in per-Vlan basis. Each multicast group has a octect string to indicate with port map. The most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port. .
What is swIGMPPortMap?
This read-only object reports, as a port bitmap, which switch ports have hosts that are members of a specific multicast group on a given VLAN. An administrator reads this to confirm the switch is correctly restricting multicast forwarding for that group to only the ports with actual interested receivers. For example, if a multicast stream is unexpectedly reaching a port with no subscribed device, the operator would check swIGMPPortMap to see if that port is incorrectly included in the group's forwarding set.
