SNMP operation

The Avaya media server provides the following Simple Network Management Protocol (SNMP) services:

This topic covers:

SNMP operation on the server

The server's SNMP service logs traps and informs generated by devices on the media server's control network, such as the Ethernet switches and UPS units.

Each device on the media server's control network must have its own SNMP agent to generate traps for it. Those agents are configured to send traps to the media server. Supported devices include:

SNMP service includes both the reception of traps and responding to requests. Trap reception is always enabled. For the server to respond to requests, the master agent needs to be running, the subagent to which the query is directed needs to be running, and the SNMP ports on the Ethernet interface to the corporate LAN need to be enabled on the server. Activation of these services is described in the next section.

If request response is enabled, the master agent on the currently active Avaya media server "listens" on the SNMP port for incoming queries and commands (gets and sets). The master agent authenticates an incoming message, then passes it on to the subagent associated with the object requested or commanded, and the subagent processes the message. Because only the master agent listens on the SNMP port for incoming messages, stopping the master agent inhibits the SNMP capability on that server.

The two Avaya media servers operate independently regarding SNMP service. Stopping the master agent or disabling SNMP service on the corporate LAN applies only to the server on which the operation is performed. These actions must be repeated on the duplicate server to enable or disable SNMP service.

Alarm reporting options

The Avaya media server supports two methods for reporting alarms. Either method, both, or no alarm-reporting method may be used at a given site.

To activate OSS alarm notification: Each server requires a USB connection to a modem that is connected to a common analog line. The modem must be configured as described in Set Modem Interface, and enabled to send and receive calls using the Enable/Disable Modem screen. Configuration of the OSS alarming method can only be done using shell commands.

To activate SNMP alarm notification:  SNMP service must be set up as follows:

Check or change SNMP status on other screens

To check or change the status of SNMP processes or services, use the following screens:

You cannot change the status of the SNMPManager process.
