IP Network Parameters
3.3.9 SNMP
The Simple Network Management Protocol is used by network management systems for mon-
itoring network-attached devices for conditions that warrant administrative attention. An SNMP
manager surveys and, if needed, configures several SNMP elements, e.g. VoIP phones.
OpenStage phones support SNMPv1.
There are currently 4 trap categories that can be sent by the phones:
Standard SNMP traps
OpenStage phones support the following types of standard SNMP traps, as defined in RFC
1157:
• coldStart: sent if the phone does a full restart.
• warmStart: sent if only the phone software is restarted.
• linkUp: sent when IP connectivity is restored.
QoS Related traps
These traps are designed specifically for receipt and interpretation by the QDC collection sys-
tem. The traps are common to SIP phones, HFA phones, Gateways, etc.
Traps for important high level SIP related problems
Currently, these traps are related to problems in registering with a SIP Server and to a failure
in remotely logging off a mobile user. These traps are aimed at a non-expert user (e.g. a stan-
dard Network Management System) to highlight important telephony related problems.
Traps specific to OpenStage phones
Currently, the following traps are defined:
TraceEventFatal: sent if severe trace events occur; aimed at expert users.
TraceEventError: sent if severe trace events occur; aimed at expert users.
