If you do not include the order order-value option in your command, the ACL will be appended to
the end of the group-policy list.

If you use this command multiple times on the same multicast group, the first matched traffic rate
configuration in sequence will take effect.
z
Once a multicast forwarding entry is created, subsequent multicast data will not be encapsulated in
register messages before being forwarded even if a register outgoing interface exists. Therefore, to
avoid forwarding failure, do not include the infinity keyword in the spt-switch-threshold
command on a switch that may become an RP (namely, a static RP or a C-RP).
Examples
# Disable RPT-to-SPT switchover on a switch that will never become an RP.
