Source-Policy - Huawei Quidway S3900 series Command Manual

Command Manual – Multicast Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
Description
Use the spt-switch-threshold command to configure the threshold value at which the
shared tree is switched to the SPT.
Use the undo spt-switch-threshold command to restore the threshold to the default
value.
By default, the shared tree is switched to the SPT when the threshold is 0.
In PIM-SM, Ethernet switches forward multicast packets through the shared tree at the
beginning. If the threshold is set to 0, the Ethernet switch at the last hop of multicast
packets will switch the shared tree to the SPT; if the threshold is set to other value
rather than 0, the switch will not switch the shared tree to the SPT.
If the acl-number argument is not specified, the threshold applies to all multicast
groups.
Example
# Specify the switch at the last hop to switch the shared tree to the SPT when it receives
the first multicast packet.

Description
Use the source-policy command to configure the router to filter the received multicast
data packets according to the source address or group address.
Use the undo source-policy command to remove the configuration.
If resource address filtering is configured, as well as basic ACLs, then the router filters
the resource addresses of all multicast data packets received. Those not matched will
be discarded.
