10.1
Overview
As of R10.2, the SNMP service is available on the OmniPCX Office, allowing network
supervision (remotely or locally) of the system from an SNMP supervisor. The number of
OmniPCX Office nodes supervised by OmniVista 8770 is limited. SNMP is a protocol
commonly used for data network supervision.
Historic, hardware anomalies and urgent alarms of the OmniPCX Office are got via the SNMP
service. Through the SNMP, an alarm report mechanism with traps (SNMP Trap V2C
mechanism) allows to report the urgent alarms of the system on the fly.
Configuration and actions on the system are provided by the OMC tool.
SNMP allows to provide a physical view of system information and equipment status, via:
-
MIB-II, which describes all the IP network side and the corresponding generic alarms
-
The host resources MIB which describes a “host” system (with all resources)
-
Some private MIBs which describe:
•
The OmniPCX Office Hardware
•
The telephony service: historic, hardware anomalies and urgent alarms tables
All these data (information and status), read from the OmniPCX Office, cannot be modified.
For more information, see: TC2093en ed.02, available from the Business Portal.

Protocol
10.2.1
Topology
The SNMP service is a mechanism to supervise remotely the system. Three SNMP protocol
versions are normalized differing from each other mainly on security aspects.
The SNMPv2c protocol is implemented on OmniPCX Office. Security is based on a community
identifier, which is sent transparently over the network for trap sent from the OmniPCX Office
and status got from the supervisor
VPN is recommended for the exchanges between the OmniPCX Office SNMP agent and the
remote supervisor. It can be offered with an network operator.
The OmniPCX Office sends its own specific traps, easily integrated with supervisors
The service is available on LAN and WAN with low security level. When enabled, a supervisor
can:
-
Receive, on the fly, the urgent alarms of the system
-
View the system’s life (some supervisors ping their agent), its configuration (hardware
description) and status at any time

When the supervisor is the network operator, it can supervise several OmniPCX Office located
