Monitoring the Cajun Switch (Layer 2 & Layer 3)

2.Use Table 16-2 to set the threshold values:

 

Table 16-2.Temperature Thresholds

 

 

 

Threshold

 

Defines...

 

 

 

High Shutdown

 

Value in degrees Celsius that when passed causes the switch to

Temperature (Layer 2)/High

 

send a trap to the network management station and triggers a

Warning Temperature

 

shutdown. By default, this value is 50 degrees Celsius. For the

(Layer 3)

 

Layer 3 CPU sensor, the default value is 100 degrees Celsius.

 

 

 

Upper Warning

 

Value in degrees Celsius that when passed causes the switch to

Temperature

 

send a warning that the temperature is approaching the high

 

 

temperature threshold. By default, this value is 45 degrees

 

 

Celsius. For the Layer 3 CPU sensor, the default value is 85

 

 

degrees Celsius.

 

 

 

Lower Warning

 

Value that in degrees Celsius that when passed causes the switch

Temperature

 

to send a warning that the temperature is approaching the low

 

 

temperature threshold. By default, this value is 5 degrees

 

 

Celsius.

 

 

 

Low Shutdown

 

How low the temperature must drop on the switch to reset the

Temperature (Layer 2)/Low

 

warning and high thresholds. This value prevents the switch

Warning Temperature

 

from sending traps continually if the temperature is hovering

(Layer 3)

 

around the threshold value. By default, this value is 0 degrees

 

 

Celsius.

 

 

 

Checking Active Alarms

Each switch stores a table of active alarms. This allows you to view a list of open issues in the switch without having to view the entire event log. By doing this, you can quickly obtain a snapshot of the switch’s health.

Viewing the Active Alarm Table

To view the Active Alarm Table in the Event Subsystem section of the Web Agent window, click Active Alarms. The Active Alarm Table opens.

Using the Event Subsystem

There are two switch system activity logs for Layer 3:

❒Event Log - stores a large table of events. The size of the table is user-settable. Because these events are stored in switch memory, the list is cleared each time the switch reboots.
