406CHAPTER 11: IGMP SNOOPING COMMANDS

History — Introduced in MSS Version 3.0.

Examples — The following command displays querier information for

VLAN orange:

WX1200# display igmp querier vlan orange

Querier for vlan orange			TTL
Port	Querier-IP	Querier-MAC
----	--------------- -----------------		-----
1	193.122.135.178 00:0b:cc:d2:e9:b4		23

The following command shows the information MSS displays when the querier is the WX itself:

WX1200# display 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 WX 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:

WX1200# display 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 67 describes the fields in this display. Table 76 on page 405 describes the fields in the display when a querier other than the WX is present.
