R3303-HP HSR6800 Routers IP Multicast Command Reference

163
Usage guidelines
To adjust the order of an existing ACL in the group-policy list, you can use the acl-number argument to
specify this ACL and set its order-value. This inserts the ACL to the position of order-value in the
group-policy list. The order of the other existing ACLs in the group-policy list remains unchanged.
To use an ACL that does not exist in the group-policy list, you can use the acl-number argument to specify
an ACL and set its order-value. This inserts the ACL to the position of order-value in the group-policy list.
If you do not include the order order-value option in your command, the ACL is appended to the end of
the group-policy list.
If you use this command multiple times on the same multicast group, the first traffic rate configuration
matched in sequence takes effect.
If the router is an RP, disabling switchover to SPT might cause multicast traffic forwarding failures on the
source-side DR. When disabling switchover to SPT, be sure you fully understand its impact on your
network.
Examples
# Create a group-policy with the basic ACL number of 2010, disable the switchover to SPT, and insert the
ACL to the first position.
<Sysname> system-view
[Sysname] pim
[Sysname-pim] spt-switch-threshold infinity group-policy 2010 order 1

match succeeds, the multicast mode is PIM-SSM. Otherwise, the multicast mode is PIM-SM.
