Status and Counters Data

Internet Group Management Protocol (IGMP) Status

The switch uses the CLI to display the following IGMP status on a per-VLAN basis:

Show Command

Output

 

 

show ip igmp

Global command listing IGMP status for all VLANs configured

 

in the switch:

 

• VLAN ID (VID) and name

 

• Active group addresses per VLAN

 

• Number of report and query packets per group

 

• Querier access port per VLAN

show ip igmp <vlan-id>

Per-VLAN command listing above IGMP status for specified

 

VLAN (VID)

show ip igmp group <ip-addr> Lists the ports currently participating in the specified group, with port type, Access type, Age Timer data and Leave Timer data.

For example, suppose that show ip igmp listed an IGMP group address of

224.0.1.22.You could get additional data on that group by executing the

following:
