The global setting is applied.
VLAN configuration mode
The prune-wait time is necessary on a LAN where multiple receivers could be listening
to the group; it gives them time to override the prune message. Configure the
multicast pimsm-snooping command with the
prune-wait keyword to modify the prune-wait time according to topology and PIM router configurations.
In accordance with RFC 4601, PIM routers delay pruning for 3.5 seconds by default, so configuring a lower prune-wait value may cause traffic disruption. You should configure a prune-wait value lower than 3.5 seconds only if the topology supports it, for example, if the group has only one receiver, and an immediate prune is needed.
The no form of the command disables PIM SM snooping for the VLAN. The
no form of the command with the
prune-wait keyword restores the default prune-wait time (5 seconds).
The following example enables PIM SM snooping for VLAN 10.
device# configure termnial device(config)# vlan 10 device(config-vlan-10)# multicast pimsm-snooping
