You must configure the SPT group and source thresholds before you configure the SPT switching period. The received register packets should exceed the threshold in the SPT switching period so that the receiver initiates the switching to the SPT.
SEFOS# configure terminal SEFOS(config)# set ip pim threshold spt-grp 10 SEFOS(config)# set ip pim threshold spt-src 15 SEFOS(config)# end
SEFOS# configure terminal SEFOS(config)# set ip pim spt-switchperiod 5 SEFOS(config)# end
