Displaying querier information
You can use the show ip multicast vlan command to display the querier information for a VLAN. This
command displays the VLAN interface status and if there is any other querier present with the
lowest IP address. The following list provides the combinations of querier possibilities:
• Active Interface with no other querier present
• Passive Interface with no other querier present
• Active Interface with other querier present
• Passive Interface with other querier present
Displaying the active interface with no other querier present
The following example shows the output in which the VLAN interface is active and no other querier
is present with the lowest IP address.
