1424 CHAPTER 90: PIM CONFIGURATION COMMANDS

infinity: Disables RPT-to-SPT switchover.

group-policyacl-number: Uses this threshold for multicast groups matching the specified multicast policy. In this option, acl-numberrefers to a basic ACL number, in the range of 2000 to 2999. If you do not include this option in your command, the threshold will apply on all multicast groups.

order order-value: Specifies the order of the ACL in the group-policy list, where order-valuehas 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-valueto a certain ACL, do not specify the same order-valuefor 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-thresholdcommand to configure the RPT-to-SPT switchover parameters.

Use the undo spt-switch-thresholdcommand to restore the default configuration.

By default, the device switches to the SPT immediately after it receives the first multicast packet from the RPT.

Note that:

To adjust the order of an existing ACL in the group-policy list, you can use the acl-numberargument to specify this ACL and set its order-value. This will insert the ACL to the position of order-valuein 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-numberargument to specify an ACL and set its order-value. This will insert the ACL to the position of order-valuein the group-policy list. If you do not include the order order-valueoption 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.

Example # Set the traffic rate threshold to trigger RPT-to-SPT switchover to 4 kbps in the public instance.

<Sysname> system-view [Sysname] pim

[Sysname-pim] spt-switch-threshold 4

#In the public instance create a group-policy with the ACL number of 2010 and the traffic rate threshold of 100 kbps, and insert the ACL to the first position.

<Sysname> system-view [Sysname] pim

[Sysname-pim] spt-switch-threshold 100 group-policy 2010 order 1
