Tracing the route from the switch to a host address
This command outputs information for each (router) hop between the switch and the destination
address. Note that every time you execute traceroute, it uses the same default settings unless
you specify otherwise for that instance of the command.
Syntax
traceroute [ ip-address | hostname ] [maxttl 1-255] [minttl
1-255] [probes 1-5] [source [ ip-address | source-vlan vid |
loopback 0-7 ]] [dstport 1-34000] [srcport 1-34000] [ip-option
[ record-route | loose-source-route | strict-source-route |
include-timestamp | include-timestamp-and-address | include
timestamp-from ]] [timeout 1-120]
Lists the IP address or hostname of each hop in the route, plus the time in
microseconds for the traceroute packet reply to the switch for each hop.
The IP address or hostname of the device to which
to send the traceroute.
[ ip-address | hostname ]
For the current instance of traceroute, changes
the minimum number of hops allowed for each
probe packet sent along the route.
[minttl 1-255 ]
• If minttl is greater than the actual number
of hops, the output includes only the hops at
and above the minttl threshold. (The hops
below the threshold are not listed.)
• If minttl matches the actual number of hops,
only that hop is shown in the output.
• If minttl is less than the actual number of
hops, all hops are listed.
For any instance of traceroute, if you want a
minttl value other than the default, you must
specify that value.
(Default: 1)
For the current instance of traceroute, changes
the maximum number of hops allowed for each
probe packet sent along the route.
[maxttl 1-255 ]
If the destination address is further from the switch
than maxttl allows, traceroute lists the IP
addresses for all hops it detects up to the maxttl
limit.
For any instance of traceroute, if you want a
maxttl value other than the default, you must
specify that value.
(Default: 30)
For the current instance of traceroute, changes
the number of queries the switch sends for each
hop in the route.
[probes 1-5 ]
For any instance of traceroute, if you want a
probes value other than the default, you must
specify that value.
(Default: 3)
The source IPv4 address, VLAN ID, or Loopback
address.
[source ip-addr | vid | loopback
0-7 ]
