Snmp Interface Traps - Patton electronics SmartNode Series Software Configuration Manual

18 • SNMP Configuration
Note The standard SNMP version 1 trap coldStart as listed below is not sup-
ported. After powering up a SmartNode 1000, 2000 or 4000 series device
sends a warmStart trap message if any trap target host is defined.

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-map-
ping' displays the relations between the indexes and the interfaces. It also lists the status of the interfaces.
SN(cfg)#show snmp-if-alias-mapping
ifIndex :
---------------------------------------------------------------------

Interface names in capital letters denote physical interfaces and in small letters logical interfaces.
The SmartNode adds an entry to event log for each Interface Traps it sends:
SN(cfg)#show log
