2.4.2 SNMP Trapping

The SNMP Trapping page enables the user to configure up to five remote managers to receive traps using the industry-standard Simple Network Management Protocol (SNMP). The user can choose between versions v2c, v3, or both along with the typical security parameters associated with each of the versions.

Note:

The SNMP Manager is provided by the customer.

The SNMP agent is responsible for SNMP-managed objects. Each managed object represents a data variable. A collection of managed objects is called a Management Information Base (MIB). In other words, a MIB is a database of network management information that is used and maintained by the SNMP protocol. The MIB objects contain the SNMP traps that are used for alarms; a readable SNMP table of current alarms in the system; and a readable SNMP table of KPI data.

A configuration mode option is provided that allows the user apply a configuration to all servers in the system or only to a specific site.

By default, system-wide traps are sent from the active Network OAM&P server while site-specific traps are sent from active Site OAM servers. Alternately, functionality may be enabled that allows individual servers to send traps, in which case individual servers interface directly with SNMP managers.

Note:

  1. Only the Active Network server allows SNMP administration. Global SNMP configuration cannot be modified if the disaster recover site is made Primary. It can be updated once original site becomes Primary again.
  2. If the customer wants to perform SNMP configuration from DR Active NOAM, then delete the SNMP configuration from primary NOAM before failover to DR.
  3. If original primary NOAM is not responding (for example, Disaster Recovery), then cleanup SNMP configuration of original primary Active NOAM from database using the command itrunc SnmpCfg before performing SNMP configuration on DR Active NOAM. This command needs to be executed on DR Active NOAM console.

The application sends SNMP traps to SNMP Managers that are registered to receive traps. IP addresses and authorization information can be viewed and changed using the SNMP administration page. For SNMP to be enabled, at least one Manager must be set up.
