238 CHAPTER 7: USING MULTICAST PROTOCOL COMMANDS Description Use the display igmp-snooping group command to view the IP multicast groups and MAC multicast groups under VLAN. This command displays the IP multicast group and MAC multicast group information of a VLAN or all the VLAN where the Ethernet Switch is located. It displays the information such as VLAN ID, router port, IP multicast group address, member ports in the IP multicast group, MAC multicast group, MAC multicast group address, and the member ports in the MAC multicast group. Example Display the multicast group information about VLAN2. display igmp-snooping group vlan 2 Multicast group table Vlan(id):2. Router port(s):GigabitEthernet1/0/1 IP group(s):the following ip group(s) match to one mac group. IP group address:230.45.45.1 Member port(s):GigabitEthernet1/0/2 MAC group(s): MAC group address:01-00-5e-2d-2d-01 Member port(s):GigabitEthernet1/0/2 The display above shows that: ■ There is a multicast group in VLAN 2; ■ The router port is GigabitEthernet 1/0/1; ■ The address of the multicast group is 230.45.45.1; ■ The member of the IP multicast group is GigabitEthernet 1/0/2; ■ MAC multicast group is 0100-5e2d-2d01; ■ The member of the MAC multicast group is GigabitEthernet 1/0/2 display igmp-snooping Syntax statistics display igmp-snooping statistics View All views Parameter None Description Use the display igmp-snooping statistics command to view the statistics information on IGMP Snooping. This command displays the statistics information about IGMP Snooping of the Ethernet Switch. It displays the information such as number of received general IGMP query packets, received IGMP specific query packets, received IGMP Version 1 and Version 2 report packets, received IGMP leave packets and error packets, and sent IGMP specific query packets.

Description
Use the
display igmp-snooping group
command to view the IP multicast groups
and MAC multicast groups under VLAN.
This command displays the IP multicast group and MAC multicast group
information of a VLAN or all the VLAN where the Ethernet Switch is located. It
displays the information such as VLAN ID, router port, IP multicast group address,
member ports in the IP multicast group, MAC multicast group, MAC multicast
group address, and the member ports in the MAC multicast group.
Example
Display the multicast group information about VLAN2.
<SW5500>
display igmp-snooping group vlan 2
***************Multicast group table***************
Vlan(id):2.
Router port(s):GigabitEthernet1/0/1
IP group(s):the following ip group(s) match to one mac group.
