Displaying querier information<br />
You can use the show ip multicast vlan command to display the querier information for a VLAN. This<br />
command displays the VLAN interface status and if there is any other querier present with the<br />
lowest IP address. The following list provides the combinations of querier possibilities:<br />
• Active Interface with no other querier present<br />
• Passive Interface with no other querier present<br />
• Active Interface with other querier present<br />
• Passive Interface with other querier present<br />
Displaying the active interface with no other querier present<br />
The following example shows the output in which the VLAN interface is active and no other querier<br />
is present with the lowest IP address.<br />
<strong>Brocade</strong>#show ip multicast vlan 10<br />
Version=2, Intervals: Query=125, Group Age=260, Max Resp=10, Other Qr=260<br />
