Installation prerequisites for SNMP support
Unified CCE SNMP support is automatically installed during the course of normal setup. No extra steps need
be taken during setup for SNMP support to be enabled. However, Microsoft Windows SNMP optional
components must be installed on Unified ICM/CCE servers for any SNMP agents to function.
Install the appropriate Microsoft Windows SNMP component(s) before installing any Unified ICM CCE
components that require SNMP monitoring. Following are the instructions to install the Microsoft Windows
SNMP components.
Note
The Microsoft SNMP component(s) are required for Cisco SNMP support. The Microsoft Windows SNMP
service is disabled as part of web setup and is replaced by the Cisco Contact Center SNMP Management
service to process SNMP requests in its place. The Cisco Contact Center SNMP Management service
provides for more sophisticated SNMP capabilities than the standard Microsoft SNMP Service.
Install Microsoft Windows SNMP components on Windows Server 2008
Complete the following steps to install the Windows SNMP components on Windows Server 2008 R2.

Cisco Contact Center SNMP solution configuration
The Cisco Contact Center SNMP solution is configurable from a Microsoft Management Console (MMC)
Snap-in.
Basic configuration
While all SNMP components are installed and enabled by default, the device is not manageable via an NMS
until the solution is properly configured. For security reasons, certain parameters are not configured by default.
The system administrator must configure the following to grant access to the agents and enable the receipt of
SNMP notifications:
1 Configure the Community Name or User Names:
• If you are using SNMP version 1 or version 2c, at least one community string must be configured
on each Unified ICM/CCE server to be managed (see below), OR
• If using SNMP version 3, at least one user name must be configured on each Unified ICM/CCE
server to be managed (see below).
2 Configure General Properties.
3 For trap forwarding, an SNMP trap destination must be configured on each Unified ICM/CCE Logger
server. You can also optionally add a Syslog Destination.
All properties can be configured using the Cisco SNMP Agent Management MMC Snap-in.
Note
Some diagnostic tools may use SNMP locally to gather information about the system using one of the
community strings configured for Windows SNMP. These community strings are not added to the Contact
Center SNMP configuration, which will cause SNMP requests from these diagnostic tools to fail. All
communities configured for Windows SNMP should be added to the Contact Center SNMP configuration.
It is not necessary for the Windows SNMP service to be started or enabled. The Windows SNMP
communities can be found in the “Security” tab by selecting “properties” for the Windows SNMP service
from the list of Windows services.

Add Cisco SNMP Agent Management Snap-in
You can configure Cisco SNMP Agent Management settings using a Windows Management Console Snap-in.
To add the Snap-in and change Cisco SNMP Management settings:
Procedure
Step 1
Step 2
Step 3
Step 4
From the Start menu select Run....
In the Start box type in mmc/32 and press ENTER.
Attention
The Cisco SNMP Agent Management Snap-In is a 32-bit snap-in and is only available when the
“/32” switch is used.
From the Console, select File > Add/Remove Snap-in
A new window appears.
Step 5
Step 6
From the Selected Snap-ins tab, verify Console Root is selected in the Snap-ins added to: field and click
Add.
In the Available Snap-inswindow, scroll down and select Cisco SNMP Agent Management.
In the Add Snap-in window click Add.
Step 7
In the Add Snap-in window click Close.
Step 8
Click OK in the Add/Remove Snap-in window.
The Cisco SNMP Agent Management Snap-in is now loaded in the console.
Saving Snap-in view
Once you have loaded the Cisco SNMP Agent Management MMC Snap-in, you can save that console view
to a file (with a .MSC file extension) that can be launched directly, instead of repeatedly adding the Snap-in
to a new MMC console view. To do so, select the File > Save As menu; a Save As dialog will appear.
Select a memorable file name such as Cisco SNMP Agent Management.msc (retain the .msc file extension)
and save the file to the desired location. The Administrative Tools (start) menu is the default location, which
makes it conveniently available for later access via the Start menu.
Configure Community Name for SNMP v1 and v2c
If you are using SNMP v1 or v2c you must configure a Community Name so that Network Management
Stations (NMSs) can access the data provided by your server. These names are left blank during installation
for security reasons.
SNMP Community Names are used to authenticate data exchange of SNMP information. An NMS can
exchange SNMP information only with servers that use the same Community Name.

Note
You can remove the community name by highlighting the name in the Configured Communities
section and clicking Remove Community.

Configure User Name for SNMP v3
If you are using SNMP v3 you must configure a User Name so that Network Management Stations (NMSs)
can access the data provided by your server. By default, these names are left blank for security reasons.

authentication is required, but authentication can be configured without configuring privacy.
• These settings must also be used on your NMS to access SNMP data from this server.
Step 9
Optionally, enter one or more IP addresses in the IP Address entry field (containing “dots”) and click Insert
to enable access solely from the NMS with the IP Address provided.
