This object enables continuous and policy-based traceroute
probing. Traceroute probing allows prefix performance to be
measured on a hop-by-hop basis. Delay, loss, and
reachability measurements are gathered for each hop from the
probe source to the target prefix.
'none'
Traceroute probing is disabled.
'delay'
Delay policy based traceroute probing is enabled.
'loss'
Loss policy based traceroute probing is enabled.
'reachability'
Reachability policy based traceroute probing is enabled.
