These features enable you to determine the traffic patterns for each port since the last reboot or reset of the switch. You can display:

A general report of traffic on all LAN ports and trunk groups in the switch, along with the per-port flow control status (On or Off).

A detailed summary of traffic on a selected port or trunk group.

 

You can also reset the counters for a specific port.

 

The menu interface and the web browser interface provide a dynamic display

 

of counters summarizing the traffic on each port. The CLI lets you see a static

 

“snapshot” of port or trunk group statistics at a particular moment.

 

As mentioned above, rebooting or resetting the switch resets the counters to

 

zero. You can also reset the counters to zero for the current session. This is

 

useful for troubleshooting. Refer to the “Note On Reset”, below.

 

 

N o t e o n R e s e t

The Reset action resets the counter display to zero for the current session, but

 

does not affect the cumulative values in the actual hardware counters. (In

 

compliance with the SNMP standard, the values in the hardware counters are

 

not reset to zero unless you reboot the switch.) Thus, using the Reset action

 

resets the displayed counters to zero for the current session only. Exiting from

 

the console session and starting a new session restores the counter displays

 

to the accumulated values in the hardware counters.
