Cisco Unity Express SNMP MIB Support
Cisco Unity Express (CUE) integrates an SNMP agent and SNMP MIBs to monitor the health and to conduct performance monitoring, data collection, and trap management for Cisco Unity Express voice-mail and auto-attendant applications. Cisco Unity Express provides a voice-mail and auto-attendant solution for small branch offices, which typically have less than 200 users.
Cisco Unity Express functionality is provided by a network management Advanced Integration Module (AIM) card that is installed inside a router. The AIM allows the Cisco Unity Express functionality to be quickly added to supported routers. To operate, the AIM needs only IP connectivity and power from the router. CUE functionality is also supported on a network module (CUE-NM) and on the extended capacity network module (CUE-NM-EC).
By configuring SNMP to send notifications to one or more monitoring computers, the network management system (NMS) application can monitor multiple CUEs. Because notifications are event driven, they cause much less network traffic than using the SNMP GET operation repeatedly to poll a population of CUEs. The SNMP management interface provides visibility into the system through SNMP GET operations and sends SNMP v2c notifications to the NMS application when events occur.

Prerequisites for the CISCO-UNITY-EXPRESS-MIB
Users of the CUE MIB should ensure the following prerequisites are met.
Restrictions for the CISCO-UNITY-EXPRESS-MIB
CISCO-UNITY-EXPRESS-MIB support is restricted to the following Cisco routers in Cisco Unity Express Release 2.2.
Information About the CISCO-UNITY-EXPRESS-MIB
The CUE MIB provides configuration information and usage of the Cisco Unity voice mail system:
CISCO-UNITY-EXPRESS-MIB Structure
The CISCO-UNITY-EXPRESS-MIB is uniquely identified within the Cisco management (9) group by the number 420. Therefore, the CISCO-UNITY-EXPRESS-MIB is 1.3.6.1.4.1.9.9.420.
Objects in the CISCO-UNITY-EXPRESS-MIB can be identified by either of the following methods.
- The object name—iso(1).org(3).dod(6).internet(1).private(4).enterprise(1).cisco(9).ciscoMgmt(9)
.CISCO-UNITY-EXPRESS-MIB(420).<Cisco Unity Express MIB-variable>
Figure 1-1 shows the position of the CISCO-UNITY-EXPRESS-MIB in the Internet MIB hierarchy. The CISCO-UNITY-EXPRESS-MIB is part of the Cisco management (9) group, which is presented by private.enterprise.cisco.ciscoMgmt. And is shown graphically in Figure 1-1.
The CISCO-UNITY-EXPRESS-MIB uses definitions from the following MIBs:
Figure 1-1 CISCO-UNITY-EXPRESS-MIB MIB Tree Structure
The CISCO-UNITY-EXPRESS-MIB structure is divided into the following groups:
The ciscoUnityExpressMIBObjects group is further divided into the following subgroups:
CISCO-UNITY-EXPRESS-MIB Objects
This section contains the Cisco Unity Express MIB object. Table 1-1 lists the CISCO-UNITY-EXPRESS-MIB objects, the maximum access for each, and their descriptions. Table 1-5 lists the CISCO-UNITY-EXPRESS-MIB object IDs (OIDs).
Cisco CUE MIB Object Groups
Table 1-2 lists the CISCO-UNITY-EXPRESS-MIB object name and the corresponding object ID mapping.
There are three CISCO-UNITY-EXPRESS-MIB groups listed in Table 1-2 :

Using Alerts
Using alerts allows more efficient use of network resources by reducing the number of messages sent and received by the NMS.
How to Use the CISCO-UNITY-EXPRESS-MIB
The following sections contain information regarding configuring and using the CISCO-UNITY-EXPRESS-MIB.
Note See the Cisco Unity Express System Monitoring Guide Release 2.2 for a list of CLI commands for use with Cisco Unity Express.
The snmp-server community string command provides access control for SNMPv1 and SNMPv2c but also continues to provide backward compatibility between different versions. The previous version of this command did not have an option to create a community string that allows SNMP messages to execute a set operation on a MIB object. An rw or ro option has been introduced for this purpose. The SNMP agent is disabled by default, and a community string is not configured.
The following example enables the SNMP agent and assigns the community string comaccess to SNMP:
The preceding example defines a community string comaccess used as a password for authentication when you access the SNMP agent. Any SNMP message sent to the SNMP agent must have the “Community Name” field of the message match the community string defined here in order to be authenticated. Entering a community string enables the SNMP agent.
The following example disables the SNMP agent and removes the previously defined community string.
Locating the CISCO-UNITY-EXPRESS-MIB
To locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at the following URL:
http://tools.cisco.com/ITDIT/MIBS/servlet/index
If Cisco MIB Locator does not support the MIB information that you need, you can also obtain a list of supported MIBs and download MIBs from the Cisco MIBs page at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
To access Cisco MIB Locator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at the following URL:
Enabling the SNMP Agent
The SNMP agent for the CISCO-UNITY-EXPRESS-MIB is disabled by default.
To enable the SNMP agent for the CISCO-UNITY-EXPRESS-MIB, perform the following steps.
Prerequisites
Be sure the router platform is a supported router and the required MIBs are installed.
DETAILED STEPS
Verifying the Enabling of the SNMP Agent
To verify that the SNMP agent has been enabled on a given network device, perform the following steps.
DETAILED STEPS
Step 1 Telnet to the target device.
Step 2 Display the running configuration on the device and examine the output for any displayed SNMP information:
Note If your CUE system is large, using the show running config command can take several minutes to display the SNMP information. As an alternative, you can use the show snmp configuration command to display only SNMP-related configuration information.
Any “snmp-server” statement appearing in the output that takes the form shown before verifies that SNMP has been enabled on the specified device.
Or alternately, use the following show snmp command to verify the SNMP agent is enabled.
Configuring the MIB Browser to Read MIB Values
For the MIB browser to read the MIB values, configure the CUE using the following CLI commands.
