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.
See Also set igmp querier on page 421
show igmp receiver-table
Displays the receivers to which a WSS forwards multicast traffic. You can display receivers for all VLANs, a single
VLAN, or a group or groups identified by group address and network mask.
