Using SNMP Traps

This section describes how to set up your system to send and receive traps. It also describes the traps that you can use to receive change notification for logical domains (domains), as well as other traps that you can use.

Sending and Receiving Traps

Send Traps

• Configure the trap.

  Edit the /etc/sma/snmp/snmpd.conf file to add the directives to define the trap, inform version, and destination.

  trapcommunity string --> define community string to be used when sending traps
  trapsink host[community [port]] --> to send v1 traps
  trap2sink host[community [port]] --> to send v2c traps
  informsink host[community [port]] --> to send informs

  For more information, see the snmpd.conf(4) man page.

Example 15-4 Sending SNMP v1 and v2c Traps

This example sends send both v1 and v2c traps to the SNMP trap daemon that runs on the same host. The /etc/sma/snmp/snmpd.conf file is updated with the following directives:

trapcommunity public
trapsink localhost
trap2sink localhost

Receive Traps

• Start the SNMP trap daemon utility.

  For information about the output format options, see the snmptrapd(1M) man page.

  The snmptrapd utility is an SNMP application that receives and logs SNMP TRAP messages. For example, the following snmptrapd command shows that a new domain was created (ldomTrapDesc = Ldom Created) with a name of ldg2 (ldomName = ldg2).

  # /usr/sfw/sbin/snmptrapd -P -F \ "TRAP from %B on %m/%l/%y at %h:%j:%k Enterprise=%N Type=%w SubType=%q \nwith Varbinds: %v \nSecurity info:%P\n\n" \ localhost:162
  TRAP from localhost on 5/18/2007 at 16:30:10 Enterprise=. Type=0 SubType=0
  with Varbinds: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (47105)
  0:07:51.05 SNMPv2-MIB::snmpTrapOID.0 = OID: SUN-LDOM-MIB::ldomCreate
  SUN-LDOM-MIB::ldomIndexNotif = INTEGER: 3 SUN-LDOM-MIB::ldomName = STRING: ldg2
  SUN-LDOM-MIB::ldomTrapDesc = STRING: Ldom Created
  Security info:TRAP2, SNMP v2c, community public
