All Implemented Interfaces:

NotificationHandler

public class FilterKnownIPAddresses
extends Object
implements NotificationHandler

Standard filter for suppression of notifications emanating from ip addresses outside defined set of addresses The filter determines the source ip address first from the snmpTrapAddress 1.3.6.1.6.3.18.1.3 varbind if this is set, or otherwise from the emanating peer ip address. This filter is implemented as a handler in the same way as user defined handlers and the only difference is that it is always registered in the beginning of the handler chain.
