Configuring The Period For An Interface To Keep The Prune State - Huawei Quidway s3700 series Configuration Manual

Quidway S3700 Series Ethernet Switches
Configuration Guide - Multicast
Applicable Environment
When the last member leaves its group, the switch sends a Prune message through an upstream
interface. After receiving the Prune message, the upstream switch performs the prune action and
stops sending multicast packets to this network segment. If other downstream switchs exist in
the network, the switchs need to send a Join message to override the prune action.
Switchs can work normally under the control of the default parameter values. Users can adjust
related parameters according to the specific network environment.
Pre-configuration Tasks

6.6.2 Configuring the Period for an Interface to Keep the Prune State

The period for an interface to keep the prune state can be set either globally or on an interface.
After the period expires, the pruned interface starts to forward messages again. If the multicast
device receives a State-Refresh message before the period expires, it resets the timer, that is, it
refreshes the prune state.
Context
Do as follows on the PIM-DM switch:

NOTE
The configuration involves the following two cases:
l Global configuration: It is valid on each interface.
l Configuration on an interface: The configuration on an interface takes precedence over the global
configuration. If the configuration on an interface is not done, the global configuration is used.
