Layer 3 Routing Commands 1657
After an IP SLA has been scheduled, the configuration may not be modified.
To modify the configuration of the operation, first stop the operation by using
the no ip schedule command and then modify the configuration.
Alternatively, delete the IP SLAs operation (using the no ip sla command)
and then reconfigure the operation with the new operation parameters.
