Source-Policy - 3Com 5500-EI PWR Reference Manual

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.
Examples
# Set the multicast source lifetime to 3000 seconds.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] pim
[Sysname-pim] source-lifetime 3000

source-policy

Syntax
source-policy acl-number
undo source-policy
View
PIM view
Parameters
acl-number: Basic or advanced ACL, in the range of 2000 to 3999.
Description
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.
Examples
# Configure the switch to accept the multicast data packets from any multicast source but 10.10.1.1.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
