SNMP Trap for Survivability

A Oracle® Enterprise Session Border Controller MIB contains objects of management data, and also information about Simple Network Management Protocol (SNMP) traps, which enable an agent to notify the management station of significant events by way of an unsolicited SNMP message. When an element sends a TRAP packet, it can include an Object Identifier (OID) and value information (bindings) to clarify the event. For more information about SNMP on the Oracle® Enterprise Session Border Controller, see the Net-Net 4000 MIB Reference Guide.

The Oracle® Enterprise Session Border Controller triggers an Enterprise SNMP trap when a SIP interface goes in or out of Survivability mode. This trap is called:

• snmp_survivability_mode_trap_send

This trap has been added to the SIP application MIB called ap-sip.mib. The trap information is as follows in this MIB:

apSipSurvivabilityNotif            	OBJECT IDENTIFIER ::= { apSipNotificationObjects 2 }
apSipSurvivabilityNotifObjects  	OBJECT IDENTIFIER ::= { apSipSurvivabilityNotif 1 }
apSipSurvivabilityNotifPrefix   	OBJECT IDENTIFIER ::= { apSipSurvivabilityNotif 2 }
apSipSurvivabilityNotifications 	OBJECT IDENTIFIER ::= { apSipSurvivabilityNotifPrefix 0 }
apSipSurvivabilityModeEnter 	NOTIFICATION-TYPE
	OBJECTS	{ apSysMgmtSipInterfaceRealmName, 		 apSysMgmtSipInterfaceIP  }
	STATUS		current
	DESCRIPTION	
	" The trap will be generated when SIP interface enters Survivability Mode."
	::= { apSipSurvivabilityNotifications 1 }
apSipSurvivabilityModeExit 		NOTIFICATION-TYPE
	OBJECTS	{ apSysMgmtSipInterfaceRealmName,
		 apSysMgmtSipInterfaceIP  }
	STATUS		current
	DESCRIPTION
        " The trap will be generated when SIP interface exits Survivability Mode and resumes normal operation."
	::= { apSipSurvivabilityNotifications 2 }
apSipSurvivabilityNotificationsGroup 	NOTIFICATION-GROUP
        NOTIFICATIONS {apSipSurvivabilityModeEnter,
			apSipSurvivabilityModeExit  }
        STATUS 	 current
        DESCRIPTION
		"Traps to monitor  SIP interface Survivability feature."
        ::= { apSipNotificationGroups  2 }

Note:

The apSysMgmtSipInterfaceRealmName and apSysMgmtSipInterfaceIP objects are imported strings defined in ap-smgmt.mib.

When this trap is generated, it contains the following information:

realmname	Realm name of the SIP interface
ipaddr	IP address of the SIP interface
mode	Specifies whether or not the SIP interface is in survivability mode. Values included with the trap are: 0 - SIP interface is OK. It is not in Survivability mode. 1 - SIP interface is in Survivability mode.

The following table identifies the Survivability OBJECT IDENTIFIERS in the Oracle MIB that the Oracle® Enterprise Session Border Controller supports.

Trap Name: OID Number	Description
