Parameters
value
: Specifies the maximum number of hops that the probe packets can traverse, in the range of 1
to 255.
Usage guidelines
The
route-option bypass-route
command sets the TTL to 1 for probe packets. The
ttl
command
does not take effect.
For a successful UDP tracert operation, make sure the maximum number of hops is not smaller than
the value set in the
init-ttl
command.
Examples
# Set the maximum number of hops to 16 for probe packets.
