Monitoring the Cajun Switch (Layer 2 & Layer 3)
Cajun P550/P220 Switch Operation Guide 16-3
2. Use Table 16-2 to set the threshold values:
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.
Table 16-2. Temperature Thresholds
Threshold Defines...
High Shutdown
Temperature (Layer 2)/High
Warning Temperature
(Layer 3) Value in degrees Celsius that when passed causes the switch to
send a trap to the network management station and triggers a
shutdown. By default, this value is 50 degrees Celsius. For the
Layer 3 CPU sensor, the default value is 100 degrees Celsius.
Upper Warning
Temperature Value in degrees Celsius that when passed causes the switch to
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
Temperature Value that in degrees Celsius that when passed causes the switch
to send a warning that the temperature is approaching the low
temperature threshold. By default, this value is 5 degrees
Celsius.
Low Shutdown
Temperature (Layer 2)/Low
Warning Temperature
(Layer 3) How low the temperature must drop on the switch to reset the
warning and high thresholds. This value prevents the switch
from sending traps continually if the temperature is hovering
around the threshold value. By default, this value is 0 degrees
Celsius.
