spt-switch-threshold (PIM view)
Use spt-switch-threshold to configure the criteria for triggering a switchover to SPT.
Use undo spt-switch-threshold to restore the default.
Syntax
spt-switch-threshold { traffic-rate | infinity } [ group-policy acl-number [ order order-value ] ]
undo spt-switch-threshold { traffic-rate | infinity } [ group-policy acl-number ]
Default
The device switches to the SPT immediately after it receives the first multicast packet.
Views
Public network PIM view, VPN instance PIM view
Default command level
2: System level
Parameters
traffic-rate: Specifies a traffic rate in kbps, in the range of 1 to 4194304.
infinity: Disables switchover to SPT.
group-policy acl-number: Specifies a basic ACL in the range of 2000 to 2999. If you do not include this
option in your command, the configuration applies to 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 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.
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.
