The health statistics feature monitors the consumable resources of a switch, and provides a 
single integrated source for Network Management Software (

NMS

), such as X-Vision, to use in 

obtaining statistics on switch performance. With the health statistics, the user can set specific 
threshold levels for consumable resources in the switch. Such resources include bandwidth 
capacity, 

CAM

 and 

CPU

 usage, and 

RAM

 memory usage. If a threshold for a particular resource 

is exceeded, a notification is sent to the 

NMS

 via an 

SNMP

 trap.

♦ Important ♦ 

You must configure your 

NMS

 to accept traps from the 

monitored switch. X-Vision allows you to set which 
network management stations receive traps. For more 
information, see the X-Vision online help.

The health statistics software monitors the resource utilization levels and thresholds of a 
switch, and at fixed intervals collects the current values for each resource being monitored. 
After obtaining the statistics, the health statistics software checks to see if any rising or falling 
threshold crossings occurred since its last poll by comparing the current poll data with the 
previous poll data. If a threshold crossing has occurred, a trap is sent to NMS (such as X-
Vision), allowing the system administrator to pinpoint possible performance issues.

Through the 

UI

 (user interface), threshold levels can be set, the sampling interval can be 

changed, and statistics (for a switch, module, or port) can be viewed or cleared.

To access the Health menu, log on to a switch via a Telnet or console session, and type the 
following command:

If the session is in terse mode, you will need to type 

 to see the menu. If you are in verbose 

mode, the following screen is displayed:

The 

 command allows you to set global thresholds for the switch. The 

, 

, 

 commands allow you to view the statistics on a switch, module, or port level, respec-

tively. The 

 command resets the statistics for this switch.
