Table 3-13: Show igmp snooping groups
Entries | Description |
|---|
Interface | The interface (port) on the multicast router that is marked as taking place in the multicast. |
Group | The multicast group identified by an IPv4 address. |
Flags | S - Member is statically configured, R - Member is learned from the network. |
Uptime | How long the member has been a part of the group. |
Group mode | As stated. |
Last reporter | In IGMPv3, a host can send a membership report that includes a list of source addresses. When the host sends a membership report in INCLUDE mode, the host is interested in group multicast traffic only from those sources in the source address list. If host sends a membership report in EXCLUDE mode, the host is interested in group multicast traffic from any source except the sources in the source address list. A host can also send an EXCLUDE report in which the source-list parameter is empty, which is known as an EXCLUDE NULL report. An EXCLUDE NULL report indicates that the host wants to join the multicast group and receive packets from all sources. |
Vlan | VLAN number ID. |
Group/Source Address | Multicast group and source addresses. |
Interface | The interface (port) on the multicast router that is marked as taking place in the multicast. |
Flags | S - Member is statically configured, R - Member is learned from the network. |
Uptime | How long the member has been a part of the group. |
Expires | Either by a timeout (IGMPv1) or by checking whether the member is still a part of the multicast (IGMPv2 or v3). Can also be statically configured. |
Last Reporter | Indicates that the host wants to join a particular multicast group. |
Version | IGMP version (v1, v2, or v3). |
