Ssm-Policy (Pim View) - 3Com S7906E Command Reference Manual

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 error information. If you do not specify an order-value, the order value of the ACL will
remain the same in the group-policy list.
Description
Use the spt-switch-threshold infinity command to configure disabling the SPT switchover.
Use the undo spt-switch-threshold command to restore the default configuration.
By default, the device switches to the SPT immediately after it receives the first multicast packet.
Note that:
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 will insert 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 will
remain 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 will insert 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 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 traffic rate
configuration matched in sequence will take effect.
For an S7900E series Ethernet switch, 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 is available. Therefore, to avoid forwarding failure, do not use
spt-switch-threshold infinity command on a switch that may become an RP (namely, a static RP
or a C-RP).
Examples
# Disable SPT switchover on a switch that will never become an RP.
