IP Multicast Registration Table
The IP Multicast Registration Table displays all the multicast groups active on
the Switch, including the multicast IP address and the corresponding VLANs.
• VLAN - A VLAN with host members that have asked to receive the indi-
cated multicast service.
• Multicast IP - A source IP address that represents a specific multicast
service.
• (Multicast Group Port Lists) - The ports that belong to the indicated
VLAN group. Read the numbers vertically; they range from 1-26. For
each port number, there are two choices:
If the letter “M” is present, it indicates that the VLAN has access to
messages transmitted by that particular port.
If there is no letter “M,” then there is no access to messages trans
mitted by that particular port.
• Learned by - Shows if this entry was learned dynamically or via IGMP
Snooping. An entry is learned dynamically if a multicast packet was seen
crossing the port, or via IGMP Snooping if an IGMP registration packet
was seen crossing the port.
