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 MIB-2 (standard MIB) and

 

Webcache MIB traps:
