NOTE
When two shared ports on an FC4-48 blade are receiving traffic and the primary port goes offline,
all the frames that are out for delivery for the primary port are dropped, but the counters show them
as dropped on the secondary port that shares the same area. Error counters increment
unexpectedly for the secondary port, but the secondary port is operating properly.
If this occurs, clear the counters using the portStatsClear command on the secondary port after the
primary port goes offline.
5. Enter the portFlagsShow command; then, check to see how a port has logged in and where a
login failed (if a failure occurred):
