R2511-HP MSR Router Series IP Multicast Command Reference(V5)

354
spt-switch-threshold (IPv6 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 acl6-number [ order order-value ] ]
undo spt-switch-threshold [ group-policy acl6-number ]
Default
The device switches to the SPT immediately after it receives the first IPv6 multicast packet.
Views
IPv6 PIM view
Default command level
2: System level
Parameters
traffic-rate: Specifies a traffic rate threshold in kbps. The value range is 1 to 4194304.
infinity: Disables switchover to SPT.
group-policy acl6-number: Specifies a basic IPv6 ACL in the range of 2000 to 2999. If you do not
include this option in your command, the configuration applies to all IPv6 multicast groups.
order order-value: Specifies the order of the IPv6 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 IPv6 ACL in the group-policy list. If you have assigned
an order-value to a certain IPv6 ACL, do not specify the same order-value for another IPv6 ACL.
Otherwise the system will give error information. If you do not specify an order-value, the order value of
the IPv6 ACL will remain the same in the group-policy list.
Usage guidelines
To adjust the order of an IPv6 ACL that already exists in the group-policy list, you can use the acl6-number
argument to specify this IPv6 ACL and set its order-value. This inserts the IPv6 ACL to the position of
order-value in the group-policy list. The order of the other existing IPv6 ACLs in the group-policy list
remains unchanged.
To use an IPv6 ACL that does not exist in the group-policy list, you can use the acl6-number argument to
specify an IPv6 ACL and set its order-value. This inserts the IPv6 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 IPv6 multicast group, the first traffic rate configuration
matched in sequence takes effect.
Examples
# Set the traffic rate threshold to trigger an SPT switchover to 4 kbps.
<Sysname> system-view
[Sysname] pim ipv6
[Sysname-pim6] spt-switch-threshold 4
# Create a group-policy with the basic IPv6 ACL number of 2010 and the traffic rate threshold of 100
kbps, and insert the IPv6 ACL to the first position.
