Command Manual – Multicast
H3C S7500E Series Ethernet Switches
Note that:
If you specify a basic ACL, the device filters all the received multicast packets
based on the source address, and discards packets that fail the source address
match.
If you specify an advanced ACL, the device filters all the received multicast
packets based on the source and group addresses, and discards packets that fail
the match.
If this command is executed repeatedly, the last configuration will take effect.
Examples
# Configure the router to accept multicast packets originated from 10.10.1.2 and
discard multicast packets originated from 10.10.1.1.

Syntax
spt-switch-threshold infinity [ group-policy acl-number [ order order-value ] ]

View

Parameters
infinity: Disables RPT-to-SPT switchover.
group-policy acl-number: Uses this threshold for multicast groups matching the
specified multicast policy. In this option, acl-number refers to a basic ACL number, in
the range of 2000 to 2999. If you do not include this option in your command, the
threshold will apply on all multicast groups.
order order-value: Specifies the order of the ACL in the group-policy list, where
order-value has an effective range of 1 to (the largest order value in the existing
group-policy list + 1), but the value range should not include the original order value of
the ACL in the group-policy list. If you have assigned an order-value to a certain ACL,
do not specify the same order-value for another ACL; otherwise the system will give
