Checking Ethernet and Fast Ethernet Port Connectivity

Note For more detailed information on checking connectivity, see
Connectivity."
Use the ping and traceroute commands to test connectivity out Ethernet or Fast Ethernet ports.
To check connectivity out a port, perform this task in privileged mode:
Task
Step 1 Ping a remote host that is located out the port you
want to test.
Step 2
Trace the hop-by-hop route of packets from the switch
to a remote host that is located out the port you want
to test.
Step 3 If the host is unresponsive, check the IP address and
default gateway that are configured on the switch.
This example shows how to ping a remote host and how to trace the hop-by-hop path of packets through
the network using traceroute:
Console> (enable) ping somehost
somehost is alive
Console> (enable) traceroute somehost
traceroute to somehost.company.com (10.1.2.3), 30 hops max, 40 byte packets
