# Configure Ten-GigabitEthernet 1/1/7 and Ten-GigabitEthernet 1/1/9 as static member ports
for multicast group 224.1.1.1.
[SwitchC] interface ten-gigabitethernet 1/1/7
[SwitchC-Ten-GigabitEthernet1/1/7] igmp-snooping static-group 224.1.1.1 vlan 100
[SwitchC-Ten-GigabitEthernet1/1/7] quit
[SwitchC] interface ten-gigabitethernet 1/1/9

Verifying the configuration
# Display information about the static router ports in VLAN 100 on Switch A.
[SwitchA] display igmp-snooping static-router-port vlan 100
VLAN 100:
Router slots (0 in total):
Router ports (1 in total):

XGE1/1/7
The output shows that Ten-GigabitEthernet 1/1/7 on Switch A has become a static router port.
# Display information about the static IGMP snooping forwarding entries in VLAN 100 on Switch C.
[SwitchC] display igmp-snooping static-group vlan 100
Total 1 entries.
VLAN 100: Total 1 entries.
(0.0.0.0, 224.1.1.1)
Host slots (0 in total):
Host ports (2 in total):
XGE1/1/7
XGE1/1/9
The output shows that Ten-GigabitEthernet 1/1/7 and Ten-GigabitEthernet 1/1/9 on Switch C have
become static member ports of the multicast group 224.1.1.1.
Troubleshooting IGMP snooping
Layer 2 multicast forwarding cannot function
Symptom
Layer 2 multicast forwarding cannot function on the switch.
Analysis
IGMP snooping is not enabled.
Solution
1. Use the display igmp-snooping command to display IGMP snooping status.
2. If IGMP snooping is not enabled, use the igmp-snooping command in system view to enable IGMP
snooping globally. Then, use the igmp-snooping enable command in VLAN view to enable IGMP
snooping for the VLAN.
