7-1CHAPTER 7TRAPSThe unit sends Trap PDUs to the NMS, using the pre-configuredNMS IP address (see lxadminNMSIPAddr). If no address has beenpre-configured, then the unit sends the Traps to the source IPaddress of the last SNMP datagram received from an NMS. If noaddress has been pre-configured, and if no datagrams have beenreceived since the unit was booted, then the unit uses the broadcastIP address.The Trap PDUs are sent from source UDP port number 161, todestination UDP port number 162, which are the SNMP standardnumbers reserved for Trap PDUs. The unit may be configured tosend an additional copy of each Trap PDU to a user specifieddestination UDP port number (see sysTrapPort).17.1 GENERIC TRAPSThe ELS10-26 issues generic and enterprise-specific (Cabletron)traps.
