The following command shows the information WSS Software displays when the querier is the WSS itself:

WSS# 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:

WSS# 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.

Table 65 on page 429 describes the fields in the display when a querier other than the WSS is present.

	Table 3: Output for show igmp querier
Field	Description
Querier for vlan	VLAN containing the querier. Information is listed separately for
	each VLAN.
Querier-IP	IP address of the querier interface.
Querier-MAC	MAC address of the querier interface.
TTL	Number of seconds before this entry ages out if the WSS does
	not receive a query message from the querier.
