• A high number of errors relative to the frames transmitted and frames received can indicate a
marginal link (see ”Correcting marginal links” on page 321 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. Enter the portFlagsShow command; then, check to see how a port has logged in and where a login
failed (if a failure occurred):
switch:admin> portflagsshow
