network:
Note
Though other protocol keywords are available with the
traceroute
privileged EXEC command, they are
not supported in this release.
This example shows how to perform a
traceroute
to an IP host:
Switch#
traceroute ip 171.9.15.10
Type escape sequence to abort.
Tracing the route to 171.69.115.10
