The 'hop' commands are used to test the connectivity of the
network.
_________________________________________________________________
hop check <nodename>
_________________________________________________________________
Initiate a hop check session to the specified host. This uses a
series of UDP probe packets with increasing IP time-to-live (TTL)
fields to determine the sequence of gateways in the path to the
specified destination. This function is patterned after the Unix
'traceroute' facility.
ICMP message tracing should be turned off before this command is
executed (see the 'icmp trace' command).
>> Example of output from 'hop check ucsd.edu':

_________________________________________________________________
hop maxttl [<hops>] Default: 30
_________________________________________________________________
Display or set the maximum TTL value to be used in hop check
sessions. This effectively bounds the radius of the search.
>> Example: hop maxttl 10
_________________________________________________________________
hop maxwait [<seconds>] Default: 5
_________________________________________________________________
Display or set the maximum interval that a hop check session will
wait for responses at each stage of the trace.
>> Example: hop maxwait 60
_________________________________________________________________
hop queries [<count>] Default: 3
_________________________________________________________________
Display or set the number of UDP probes that will be sent at each
stage of the trace.
>> Example: hop queries 2
_________________________________________________________________
hop trace [on | off] Default: off
_________________________________________________________________
Display or set the flag that controls the display of additional
information during a hop check session.
>> Example: hop trace on
