Default level
2: System level
Parameters
infinity: Disables SPT switchover.
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 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 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 spt-switch-threshold to configure the SPT switchover parameters.
Use undo spt-switch-threshold to restore the default.
By default, the device switches to the SPT immediately after it receives the first multicast packet.
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 takes effect.
For a switch or a multi-core device, 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 include the infinity keyword in the
spt-switch-threshold command on a switch or a multi-core device that might become an RP (namely, a
static RP or a C-RP).
