1516 ExtremeWare Software 7.3.0 Command Reference Guide
IP Multicast Commands
configure pim spt-threshold
configure pim spt-threshold <last hop router threshold> {<rp threshold>}
Description
Configures the threshold, in kbps, for switching to SPT. On leaf routers, this setting is based on data
packets. On the RP, this setting is based on register packets.
Syntax Description
Default
The default setting is 0.
Usage Guidelines
For the best performance leveraged by hardware forwarding, use default value “0,0”, or small values
below 16. From release 6.2.2 onwards, since the RP learns the source address from the register message,
the RP threshold has no effect.
Example
The following command sets the threshold for switching to SPT:
configure pim spt-threshold 4 16
