Step 4 Specify values for the following fields:
• Read-Only Community String:
Specify a string to enable the Clean Access Server to respond to snmpget and snmpwalk requests
with the correct community string. Leave this field blank to disable all Clean Access Server
responses to SNMP polling of the Clean Access Server.
• Disk Trap Threshold%: (default is 50%)
A trap will be sent when root partition free space falls below specified percentage.
• One-Minute Load Average Threshold: (default is 3.0)
A trap will be sent when the one-minute load average exceeds the threshold set here. Enter load
averages as per standard unix definition.
• Five-Minute Load Average Threshold: (default is 2.0)
A trap will be sent when the 5-minute load average exceeds the threshold set here. Enter load
averages as per standard unix definition.
• Fifteen-Minute Load Average Threshold: (default is 1.0)
A trap will be sent when the 15-minute load average exceeds the threshold set here. Enter load
averages as per standard unix definition.
• Swap Threshold: (default is 50%)

Step 5 Click Update to update the SNMP configuration with new thresholds.
Add New Trapsink to CAS
The Clean Access Server can be configured to send traps by adding trap sinks. All traps sent are version
1 (v1) traps. A copy of each trap will be sent to each trapsink.
Step 1 Click the Add New Trapsink link in the upper-right-hand corner of the pane to bring up the Add New
Trapsink form similar to Figure 13-5.
Step 2 Enter a Trapsink IP.
Step 3 Enter a Trapsink Community string.
Step 4 Enter an optional Trapsink Description.
Step 5 Click Update to update the SNMP Trapsink table.
Once trapsink configuration is complete, the Clean Access Server will send DISMAN-EVENT style
traps which refer to UCD table entries. The Clean Access Server also sends traps if the root partition
falls below a configured amount of space remaining (which defaults to 50%), and if the CPU load is
above the configured amount for 1, 5 or 15 minutes.
