Introduction

This document describes how to configure Management Information Base (MIB) Trap Parameters for Cisco Unity Connection for Simple Network Management Protocol (SNMP) monitoring.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on Cisco Unity Connection 7.x and later.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

SNMP MIB IDs

SNMP allows access to a MIB, which is a collection of information that is organized hierarchically. MIBs comprise managed objects, which are identified by object identifiers. A MIB object, which contains specific characteristics of a managed device, comprises one or more object instances (variables).

SNMP MIB

The SNMP interface provides these Cisco Standard MIBs:

  • CISCO-CDP-MIB - Use the Cisco Unified Communications Manager CDP subagent in order to read the Cisco Discovery Protocol MIB (CISCO-CDP-MIB). This MIB enables Cisco Unified Communications Manager and Cisco Unity Connection to advertise themselves to other Cisco devices on the network.

  • CISCO-SYSLOG-MIB - Syslog tracks and logs all system messages, from informational through critical. With this MIB, network management applications can receive syslog messages as SNMP traps.

  • CISCO-UNITY-MIB - The CISCO-UNITY-MIB uses the Connection SNMP Agent in order to get information about Cisco Unity Connection.

  • CISCO-CCM-MIB - The SNMP extension agent resides in the server and exposes the CISCO-CCM-MIB, which provides detailed information about devices that are known to the server. In the case of a cluster configuration, the SNMP extension agent resides in each server in the cluster. The CISCO-CCM-MIB provides device information such as device registration status, IP address, description, and model type for the server (not the cluster, in a configuration that supports clusters).

Note: Cisco Unity Connection supports all of these MIBs except for CISCO-CCM-MIB.

Configure CISCO-UNITY-MIB Trap Parameters

The Connection SNMP Agent does not enable trap notifications, though traps can be triggered by Cisco Unity Connection alarms. You can view Cisco Unity Connection alarm definitions in Cisco Unity Connection Serviceability on the Alarm Message Definitions screen.

Configure CISCO-SYSLOG-MIB Trap Parameters

Use these guidelines in order to configure CISCO-SYSLOG-MIB trap settings on your system:

  • Use the SNMP Set operation in order to set clogsNotificationEnabled (1.3.6.1.4.1.9.9.41.1.1.2) to true. For example, use the net-snmp set utility in order to set this OID to true from the Linux command line:

    snmpset -c <community
       string> -v2c <transmitter
       ipaddress> 1.3.6.1.4.1.9.9.41.1.1.2.0 i 1
    

    Note: You can also use any other SNMP management application for the SNMP Set operation.

  • Use the SNMP Set operation in order to set clogMaxSeverity (1.3.6.1.4.1.9.9.41.1.1.3) value. For example, use the net-snmp set utility in order to set this OID value from the Linux command line:

    snmpset -c public -v2c 1<transmitter
       ipaddress> 1.3.6.1.4.1.9.9.41.1.1.3.0 i
       <value>
    
    
  • Enter a severity number for the <value> setting. Severity values increase as severity decreases. A value of 1 (Emergency) indicates highest severity, and a value of 8 (Debug) indicates lowest severity. The syslog agent ignores any messages greater than the value that you specify. For example, in order to trap all syslog messages, use a value of 8.

SNMP Configuration Checklist

This is an overview of the steps needed in order to configure SNMP:

  1. Install and configure the SNMP NMS.

  2. In the Control Center - Network Services window, verify that the system started the SNMP services.

  3. The Unity Connection SNMP Agent service automatically activates.

  4. If you are using SNMP V1/V2c, configure the community string.

  5. If you are using SNMP V3, configure the SNMP user.

  6. Configure the notification destination for traps or informs.

  7. Configure the system contact and location for the MIB2 system group.

  8. Configure trap settings for CISCO-SYSLOG-MIB.

  9. Restart the Master Agent service.
