DWS-1008# show igmp querier vlan orange
Querier for vlan orange
Port Querier-IP
---- ---------------
1 193.122.135.178
The following command shows the information MSS displays when the querier is the switch
itself:
DWS-1008# show igmp querier vlan default
Querier for vlan default:
I am the querier for vlan default, time to next query is 20
The output indicates how many seconds remain before the pseudo-querier on the switch
broadcasts the next general query report to IP address 224.0.0.1, the multicast all-systems
group.
If IGMP snooping does not detect a querier, the output indicates this finding, as shown in the
following example:
DWS-1008# show igmp querier vlan red
Querier for vlan red:
There is no querier present on vlan red
This condition does not necessarily indicate a problem. For example, election of the querier
might be in progress.
Output for show igmp querier describes the fields in the display when a querier other than
the switch is present.
