Known Display Problem And Workaround; Clearing Monitor Counters - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Known display problem and workaround

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 on the secondary port after primary port goes offline.

Clearing monitor counters

Before you clear statistics counters, verify the valid monitor numbers on a specific port using the
perfMonitorShow command, to make sure the correct monitor counters are cleared. To clear statistics
counters for all or a specified monitor, use the perfMonitorClear command. After the command has
been executed, the Telnet shell confirms that the counters on the monitor have been cleared.
The command format is:
perfmonitorclear --class monitor_class [slotnumber/]portnumber
[monitorId]
