Browse IGMP Status

The Browse IGMP Status function allows you to browse Internet Group Management Protocol (IGMP). The
Switch is able to recognize IGMP queries and reports sent between stations and an IGMP router. When
enabled for IGMP snooping, the Switch can open or close a port to specific devices based on the IGMP
messages sent from the device to the router or vice versa.
To display the IP Multicast & IGMP Information screen, choose Network Monitoring from the main
menu and then choose Browse IGMP Status. The following screen appears:
Figure 6-60. IP Multicast & IGMP Information screen
This screen displays the number of IGMP queries and reports for each active IP multicast group detected by
the Switch. You can also view which Switch ports support each multicast group and enter a VLAN ID number
in the field on the right.
The fields displayed are defined as follows:
♦ IGMP Snooping Indicates whether IGMP snooping is Enabled or Disabled.
♦ Age-out Timer Displays the time the Switch waits between IGMP queries.
♦ VID Enter the desired VLAN ID number.
♦ Multicast IP Add. The Multicast IP address of the Multicast group being displayed.
♦ Multicast MAC Addr. The Multicast MAC address of the multicast group being displayed.
♦ Queries (Tx) The number of IGMP requests sent by the switch.
♦ Queries (Rx) The number of IGMP requests that have arrived at a switch port.
♦ Reports The number of notifications sent from each station to the IGMP host, signifying that the
station is still (or wants to be) part of a multicast group.
