Other network troubleshooting techniques

Other network troubleshooting techniques include the following.

Console and Syslog messages

When a switch experiences a problem, review the console and Syslog messages. The switch displays
these informative messages when state changes and system problems occur. Syslog messages can be
viewed by using the /info/sys/log command. For more information on interpreting syslog messages,
see the HP 1:10Gb Ethernet BL-c Switch Command Reference.

Ping

To verify station-to-station connectivity across the network, execute the following command:
ping <host name> | <IP address> [ (number of tries) [ msec delay ]]
The IP address is the hostname or IP address of the device. The number of tries (optional) is the number of
attempts (1-32). Msec delay (optional) is the number of milliseconds between attempts.

Trace route

To identify the route used for station-to-station connectivity across the network, execute the following
command:
traceroute <host name> | <IP address> [<max-hops> [ msec delay ]]
The IP address is the hostname or IP address of the target station. Max-hops (optional) is the maximum
distance to trace (1-16 devices). Msec delay (optional) is the number of milliseconds to wait for the
response.
