The configured multicast source lifetime applies to all (S, G) entries in the PIM routing table and the 

multicast routing table rather than on a specific (S, G) entry, and the configuration changes the aging 

time of all the existing (S, G) entries.

acl-number: Basic or advanced ACL, in the range of 2000 to 3999.  

Use the source-policy command to configure the switch to filter the received multicast data packets as 

per the source address(es) or source and group addresses defined in the ACL rule.  

Use the undo source-policy command to remove the configuration. 

If a basic ACL is employed in the command, the switch filters all the received multicast data packets as 

per the defined resource address(es). Those fail to pass the filtering will be discarded.  

If an advanced ACL is employed in the command, the switch filters all the received multicast data 

packets as per the defined resource and group addresses. Those fail to pass the filtering will be 

discarded.  

This feature filters not only multicast data packets, but also the multicast data encapsulated in 

registration messages.  

The new configuration overwrites the old one if you run the command for a second time.
