Managed Switch CLI Manual, Release 8.0.3

v1.0, July 2010
traceroute
Use the traceroute command to discover the routes that packets actually take when traveling
to their destination through the network on a hop-by-hop basis. Traceroute continues to provide a
synchronous response when initiated from the CLI.
Using the options described below, you can specify the initial and maximum time-to-live (TTL) in
probe packets, the maximum number of failures before termination, the number of probes sent for
each TTL, and the size of each probe.
Default • count: 3 probes
• interval: 3 seconds
• size: 0 bytes
• port: 33434
• maxTtl: 30 hops
• maxFail: 5 probes
• initTtl: 1 hop
•
Format traceroute <ipaddr|hostname> [initTtl <initTtl>] [maxTtl <maxTtl>]
[maxFail <maxFail>] [interval <interval>] [count <count>]
[port <port>] [size <size>]
Mode Privileged EXEC
Parameter Description
ipaddr|hostname The ipaddr value should be a valid IP address. The hostname value should be
a valid hostname.
initTtl Use initTtl to specify the initial time-to-live (TTL), the maximum number of router
hops between the local and remote system. Range is 0 to 255.
maxTtl Use maxTtle to specify the maximum TTL. Range is 1 to 255.
maxFail Use maxFail to terminate the traceroute after failing to receive a response for this
number of consecutive probes. Range is 0 to 255.
interval Use interval to specify the time between probes, in seconds. Range is 1 to 60
seconds.
count Use the optional count parameter to specify the number of probes to send for each
TTL value. Range is 1 to 10 probes.
port Use the optional port parameter to specify destination UDP port of the probe. This
should be an unused port on the remote destination system. Range is 1 to 65535.
size Use the optional size parameter to specify the size, in bytes, of the payload of the
Echo Requests sent. Range is 0 to 65507 bytes.
