SNMP

authenticationFailure

Table 1. authenticationFailure properties
Property name	Value
Application name	SNMP
Event ID	2003
Event name	authenticationFailure
SNMP notification prefix and OID	SNMPv2-MIB.snmpTraps.5
Default severity	minor
Source stream	security
Message format string	Request PDU failed authentication for $subject$, from IP $sourceUDP$
Cause	An authenticationFailure trap signifies that the SNMP entity has received a protocol message that is not properly authenticated. While all implementations of SNMP entities MAY be capable of generating this trap, the snmpEnableAuthenTraps object indicates whether this trap will be generated.
Effect	The offending PDU is ignored. The requester will time out waiting for a response.
Recovery	If the PDU was from a legitimate requester, then 1) configure the requester to use correct authentication, privacy, MP method, etc. 2) configure the agent to have corresponding access If the PDU was not from a legitimate requester, then use the printed IP address to find the source of the PDU and deal with it appropriately.

coldStart

Table 2. coldStart properties
Property name	Value
Application name	SNMP
Event ID	2001
Event name	coldStart
SNMP notification prefix and OID	SNMPv2-MIB.snmpTraps.1
Default severity	major
Source stream	main
Message format string	SNMP agent cold start
Cause	The SNMP agent was started. The coldStart trap signifies that the SNMP entity, supporting a notification originator application, is reinitializing itself and that its configuration may have been altered.
Effect	The system will respond to SNMP requests. The system will send SNMP notifications. Applications will notice counter discontinuities. System configuration may have been altered.
Recovery	To recover from counter discontinuities, re-poll relevant counters to establish a new baseline. Re-poll relevant objects to discover present configuration.

fallingAlarm

Table 3. fallingAlarm properties
Property name	Value
Application name	SNMP
Event ID	2102
Event name	fallingAlarm
SNMP notification prefix and OID	RMON-MIB.rmonEventsV2.2
Default severity	major
Source stream	main
Message format string	RMON alarm: $alarmDescription$
Cause	An RMON alarm entry crossed its falling threshold and generated an event that is configured for sending SNMP traps.
Effect	N/A
Recovery	N/A

linkDown

Table 4. linkDown properties
Property name	Value
Application name	SNMP
Event ID	2004
Event name	linkDown
SNMP notification prefix and OID	SNMPv2-MIB.snmpTraps.3
Default severity	warning
Source stream	main
Message format string	Interface $subject$ is not operational
Cause	A linkDown trap signifies that the SNMP entity, acting in an agent role, has detected that the ifOperStatus object for one of its communication links is about to enter the down state from some other state (but not from the notPresent state). This other state is indicated by the included value of ifOperStatus.
Effect	The indicated interface is taken down.
Recovery	If the ifAdminStatus is 'down' then the interface state is deliberate and there is no recovery. If the ifAdminStatus is 'up' then try to determine that cause of the interface going down: cable cut, distal end went down, etc.

linkUp

Table 5. linkUp properties
Property name	Value
Application name	SNMP
Event ID	2005
Event name	linkUp
SNMP notification prefix and OID	SNMPv2-MIB.snmpTraps.4
Default severity	warning
Source stream	main
Message format string	Interface $subject$ is operational
Cause	A linkUp trap signifies that the SNMP entity, acting in an agent role, has detected that the ifOperStatus object for one of its communication links left the down state and transitioned into some other state (but not into the notPresent state). This other state is indicated by the included value of ifOperStatus.
Effect	The indicated interface is brought up.
Recovery	There is no recovery.

risingAlarm

Table 6. risingAlarm properties
Property name	Value
Application name	SNMP
Event ID	2101
Event name	risingAlarm
SNMP notification prefix and OID	RMON-MIB.rmonEventsV2.1
Default severity	major
Source stream	main
Message format string	RMON alarm: $alarmDescription$
Cause	An RMON alarm entry crossed its rising threshold and generated an event that is configured for sending SNMP traps.
Effect	N/A
Recovery	N/A

snmpdError

Table 7. snmpdError properties
Property name	Value
Application name	SNMP
Event ID	2201
Event name	snmpdError
SNMP notification prefix and OID	TIMETRA-SYSTEM-MIB.tmnxSysNotifications.21
Default severity	major
Source stream	main
Message format string	SNMP Error: $tmnxSnmpdErrorMsg$
Cause	The Snmp daemon detected an error.
Effect	N/A
Recovery	N/A

warmStart

Table 8. warmStart properties
Property name	Value
Application name	SNMP
Event ID	2002
Event name	warmStart
SNMP notification prefix and OID	SNMPv2-MIB.snmpTraps.2
Default severity	major
Source stream	main
Message format string	SNMP agent warm start
Cause	The SNMP agent was re-started. A warmStart trap signifies that the SNMP entity, supporting a notification originator application, is reinitializing itself such that its configuration is unaltered.
Effect	The system will respond to SNMP requests. The system will send SNMP notifications. Applications will notice counter discontinuities. System configuration has not been altered.
Recovery	To recover from counter discontinuities, re-poll relevant counters to establish a new baseline. There is no need to re-poll relevant objects to discover present configuration.
