As a first thought that comes to mind, the configuration needs to be removed and then reapplied. A better way is to issue the following command under configuration mode to clear IP SLA statistics –

R1(config)#ip sla monitor restart 1 >>>>> where “1” is Entry number

or

R1(config)#ip sla restart 1 >>>>> where “1” is Entry number
Below is the IP SLA statistics output before clear counters or restarting –

R1#show ip sla monitor statistics
