status of the interfaces.
linkDown TRAP-TYPE
ENTERPRISE snmp
VARIABLES
{ ifIndex }
DESCRIPTION
"A linkDown trap signifies that the sending protocol entity
recognizes a failure in one of the communication links represented
in the agent's configuration."
::= 2
Note: The linkDown trap is not sent if any of the ISDN ports is gone down.
linkUp TRAP-TYPE
ENTERPRISE snmp
VARIABLES
{ ifIndex }
DESCRIPTION
"A linkUp trap signifies that the sending protocol entity recognizes
that one of the communication links represented in the agent's
configuration has come up."
::= 3
Note: The linkUp trap is not sent if any of the ISDN ports has come up.
authenticationFailure TRAP-TYPE
ENTERPRISE snmp
DESCRIPTION
"An authenticationFailure trap signifies that the sending protocol
entity is the addressee of a protocol message that is not properly
authenticated. While implementations of the SNMP must be capable of
generating this trap, they must also be capable of suppressing the
emission of such traps via an implementation-specific mechanism."
::= 4
Note: The authenticationFailure trap is sent after trying to access any MIB object with a SNMP
community string, which does not correspond to the system setting.
coldStart TRAP-TYPE
ENTERPRISE snmp
DESCRIPTION
"A coldStart trap signifies that the sending protocol entity is
reinitializing itself such that the agent's configuration or the
protocol entity implementation may be altered."
::= 0
Note: The standard SNMP version 1 trap coldStart as listed below is not supported. After powering
up a SmartNode 1000 or 2000 series device sends a warmStart trap message if any trap target host is
defined.
20.13 SNMP Interface Traps
The SmartNode emits Interface Traps (‘linkUp’, ‘linkDown’) when the status of logical or physical
interfaces change. Logical interfaces are interfaces defined in the IP context (IP interfaces) and
interfaces defined in the CS context (PSTN, ISoIP, and H323 interfaces). Physical interfaces are ‘ports’
in the SmartNode terminology (Ethernet, ISDN, and Serial Ports).
The SmartNode assigns an index to each interface (‘ifIndex’) in order to identify the Interface Traps.
These assignments depend on the hardware and software configurations. The command ‘show
snmp-if-alias-mapping’ displays the relations between the indexes and the interfaces. It also lists the
