Configuring IP Multicast Switching

Restoring the Querier Timeout

To restore the neighbor querier to its default (i.e., 260 seconds) value you use the no form of the
multicast querier-timeout
-> ip multicast no querier-timeout

Modifying the Querier Aging and Election Timeout

The default IPMS querier aging and election timeout (i.e., the time for which a currently elected querier is
aged and a new multicast querier is elected) is 255 seconds. The following subsections describe how to
configure a user-specified querier aging and election timeout value and how to restore it with the
ip multicast other-querier-timeout

Configuring the Querier Aging and Election Timeout

You can modify the IPMS querier aging and election timeout from 0 to 4294967295 seconds by entering
ip multicast other-querier-timeout
election timeout to 120 seconds you would enter:
-> ip multicast other-querier-timeout 120

Restoring the Querier Aging and Election Timeout

To restore the querier aging and election timeout to its default (i.e., 255 seconds) value you use the no
form of the ip multicast other-querier-timeout
-> ip multicast no other-querier-timeout

Modifying the Multicast Priority

The default IP multicast priority (i.e., the IP multicast priority value on all IPMS data queues used in the
switch) is low. The following subsections describe how to configure a user-specified multicast priority
value and how to restore it with the
Note. Multicast packets always have higher priority than unicast packets. During heavy multicast traffic
loads, unicast packet loss may result.

Configuring the Multicast Priority

You can modify the IP multicast priority to low, medium, or urgent by entering
followed by low, medium, high, or urgent. For example, to set the multicast priority to urgent you would
enter:
-> ip multicast priority urgent

Restoring the Multicast Priority

To restore the IP multicast priority to its default (i.e., low) value you use the no form of the
priority command by entering:
-> ip multicast no priority
