SNMP network management
Simple Network Management Protocol (SNMP)-based Network
Management Systems (NMS) provide a useful way of monitoring a real-time
network from end to end. This is important for networks using VoIP. User
complaints of slow downloads are no longer enough to diagnose problems.
An NMS can ensure that problems on a network running real-time traffic are
solved quickly to maintain high-quality service.
SNMP NMS software can be configured to perform the following actions:
• map the network
• monitor network operation through polling of network devices
• centralized alarm management through SNMP traps
• notify network administrators of problems
IP Trunk 3.01 (and later) can be integrated into an NMS to provide an
complete view of the converged voice and data network. Problems can
be isolated much more quickly when looking at the entire network. An IP
trunk card can send alarms through SNMP traps to the NMS. Basic card
information can be queried from an IP trunk card. The format of the IP Trunk
3.01 (and later) SNMP traps and structure of management information is
provided within the IP Trunk 3.01 (and later) Management Information
Base (MIB). To obtain the IP Trunk 3.01 (and later) MIB, contact the Nortel
representative.
SNMP Agent support is provided in TM 3.1. This integrates TM 3.1 with
existing NMS software, which allows alarms collected from an IP Trunk
3.01 (and later) node and the system to be forwarded to the NMS from a
single point of contact with the PBX.
Nortel also provides a complete line of Enterprise Network management
software with Optivity Enterprise Network Management Solutions product
line.
IP Trunk 3.01 (and later) network inventory and configuration
Record the current IP Trunk 3.01 (and later) design and log all adds, moves
and changes to the IP Trunk 3.01 (and later) network that occur. The
following data must be kept:
• ITG site information
— location
— dialing plan
— IP addressing
• Provisioning of IP Trunk 3.01 (and later) nodes
