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:

downloaded.
