SNMP Traps | You can configure the Webcache to automatically generate Simple | |
| Network Management Protocol (SNMP) traps when certain significant | |
| system events occur. An SNMP trap is a message generated by the | |
| Webcache in response to a particular event. It is sent to a specified | |
| network management station in your network which receives and filters | |
| it. You can configure the network management station to log the | |
| generated traps, filter out the traps that you are not interested in and | |
| issue event notifications. The structure and content of the SNMP traps are | |
| defined in the Management Information Bases (MIBs) that the Webcache | |
| supports. |
|
| The Webcache supports the following | |
| Webcache MIB traps: |
