5 Troubleshooting
If it is clear that a particular component system is at fault in a problem situation, go directly to that
component. If it is not clear, the best approach is to troubleshoot using the inside-out method.
You may check on the status of your iPBridge using
the ExpressNAV interface. Refer to
ATTO
ExpressNAV interface on page 25 to see which pages
may contain the information you need. You may also
look for information by using the diagnostic CLI
commands, enumerated in
Diagnostic commands on
page 39, in the Advanced page of the ExpressNAV
interface, or by using the CLI directly (refer to
CLI
provides ASCII-based interface on page 31.)
To start and use the ExpressNAV interface, including
how to access the version information, refer to
ATTO
ExpressNAV interface on page 25.

To troubleshoot using the inside out method, begin with the device(s) connected to the iPBridge first, then work
your way out.

Check the iPBridge event and trace logs
Check the iPBridge event log through the CLI. Refer
