<ip-address | hostname>
The IP address or hostname of the device to which to send the
traceroute.
[minttl < 1-255 >]
For the current instance of traceroute , changes the minimum
number of hops allowed for each probe packet sent along the
route. If
minttl is greater than the actual number of hops, then
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, then 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)
[maxttl < 1-255 >]
For the current instance of
traceroute
, changes the maximum
number of hops allowed for each probe packet sent along the
route. If the destination address is further from the switch
than
maxttl
allows, then
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)
[timeout < 1-120 >]
For the current instance of
traceroute
, changes the timeout
period the switch waits for each probe of a hop in the route.
For any instance of
traceroute,
if you want a
timeout
value
other than the default, you must specify that value. (Default:
5 seconds)
[probes < 1-5 >]
For the current instance of
traceroute
, changes the number of
queries the switch sends for each hop in the route. For any
instance of
traceroute,
if you want a
probes
value other than
the default, you must specify that value. (Default: 3)
[source <ip-addr | vlan-id>]
The source IP address or VLAN. The source IP address must
be owned by the router. If a VLAN is specified, the IP address
associated with the specified VLAN is used
A Low Maxttl Causes Traceroute To Halt Before Reaching the
Destination Address.
For example, executing
traceroute
with its default
values for a destination IP address that is four hops away produces a result
similar to this:
