Parameter
traffic-rate: Switch rate threshold from the RPT to the SPT in Kbps, ranging from 0 to
65535. By default, the switch threshold value is 0, i.e., switching starts when the RPT
receives the first data packet.
infinity: Indicates never to switch to SPT.
acl-number: Number of basic IP ACL, defining the range of a multicast group. The value
ranges from 2000 to 2999.
order-value: Order of the newly-added or refreshed group-policy in the group-policy
table, ranging from 1 to 99.
Description
Use the spt-switch-threshold command to set the packet rate threshold when the PIM
leaf router switches from the RPT to the SPT.
Use the undo spt-switch-threshold command to restore the default setting.
Use the order command to regulate the order of the group-policy. In addition, the
system chooses SPT switch threshold according to the order of group-policy, which is
more flexible and increases efficiency.
Example
# Set the threshold value to 4 kbps. If the transmission rate from the source to the
multicast group is higher than the value, the router will switch to the SPT toward the
source.
