3 Configuring the Switch

Displaying Multicast Group Information

When IGMP (Layer 3) is enabled on this switch the current multicast groups learned via IGMP can be displayed in the IP/IGMP/Group Information page. When IGMP (Layer 3) is disabled and IGMP (Layer 2) is enabled, you can view the active multicast groups in the IGMP Snooping/IP Multicast Registration Table (see

page 3-175).

Command Attributes

•Group Address – IP multicast group address with subscribers directly attached or downstream from this switch.

•Interface – The interface on this switch that has received traffic directed to the multicast group address.

•Last Reporter – The IP address of the source of the last membership report received for this multicast group address on this interface. If no membership report has been received, this object has the value 0.0.0.0.

•Up time – The time elapsed since this entry was created.

•Expire – The time remaining before this entry will be aged out. (Default: 260 seconds)

•V1 Timer – The time remaining until the switch assumes that there are no longer any IGMP Version 1 members on the IP subnet attached to this interface. (Default: 400 seconds)

-If the switch receives an IGMP Version 1 Membership Report, it sets a timer to note that there are Version 1 hosts present which are members of the group for which it heard the report.

-If there are Version 1 hosts present for a particular group, the switch will ignore any Leave Group messages that it receives for that group.
