Parameter
acl-number: Number of basic or advanced ACL, ranging from 2000 to 3999.
Description
Use the multicast packet-boundary command to configure a multicast forwarding
boundary.
Use the undo multicast packet-boundary command to remove the multicast
forwarding boundary configured.
By default, no multicast forwarding boundary is configured.
You can set boundary conditions for multicast packets on an interface via basic or
advanced Access Control List (ACL). Packets denied by the ACL will be discarded. The
source address of a multicast packet can be filtered through the basic ACL. Both the
source address and the destination address (source group address) of a multicast
packet can be filtered through the advanced ACL.
Example
# Set boundary conditions for multicast packets through the basic ACL 2001.
[3Com-Ethernet1/0/1] multicast packet-boundary 2001
