154 Troubleshooting
For example:
• A high number of errors relative to the frames transmitted and frames received can indicate a
marginal link (see ”Correcting marginal links” on page 159 for additional information).
• A steadily increasing number of errors can indicate a problem. Track errors by sampling the port
errors every five or ten minutes.
5. Issue the portFlagsShow command and then check to see how a port has logged in and where a
login failed (if a failure occurred).
For example:
6. Issue the portLogDumpPort portid command, where portID is the port number, and then view
the device to switch communication.
