Configuring SNMP Security
This section describes how to set the SNMP agent community name.
Caution The Windows 2000 SNMP agent provides security through the use of community names and authentication traps. You must configure the community name to access any management information base (MIB) in a Cisco CallManager system. Change the community name to limit access to the Cisco CallManager system.
Note Refer to the Microsoft Windows 2000 online help for SNMP configuration details.
Procedure
Step 1 Choose Start > Settings > Control Panel.
Step 2 Double-click Administrative Tools.
Step 3 Double-click Services.
Step 4 Right-click SNMP Service.
Step 5 Choose Properties.
Step 6 Click the Security tab.
Step 7 In Accepted community names field, click the Add button.
Step 8 In the Community name field, enter the name, and in the community rights field, choose either READ-ONLY or READ-WRITE.
Note To change the Cisco CallManager trap configuration parameters, you need to use a community with READ-WRITE privileges.
Step 9 Click the Add button.
Step 10 Choose the Accept SNMP packets from these hosts option to allow only specific network management system (NMS) hosts to query the SNMP extension agent.
Step 11 Click the Add button.
Step 12 Enter the IP address for the hosts that are allowed to query the SNMP extension agent.
Step 13 Click the Add button.
Step 14 Check the Send Authentication Trap check box if you want to receive SNMP authentication failure traps.

Step 4 Right-click SNMP Service.
Step 5 Choose Properties.
Step 6 Click the Traps tab.
Step 7 In the Community name field, enter the community name to be used in the trap messages that are generated from this host.
Step 8 Click the Add to list button.
Step 9 In the Trap destinations field, click the Add button.
Step 10 In the Trap destinations field, enter the IP address or hostname of the trap destination.
Step 11 Click the Add button.
Repeat Steps 9 through 11 for each trap destination that is required.
Step 12 Click the OK button.

Starting the Cisco CallManager SNMP Extension Agent
This section describes how to start the Cisco CallManager SNMP extension agent.
Note The SNMP service should start automatically when the system boots. Start the SNMP service only if it does not start automatically.
Procedure
Step 1 Choose Start > Settings > Control Panel.
Step 2 Double-click Administrative Tools.
Step 3 Double-click Services.
Step 4 Right-click SNMP Service.
Step 5 From the toolbar, choose Start Service.
Note The dynamic tables such as phoneTable, gatewayTable, etc., get populated only if the local Cisco CallManager service is up and running. The static tables such as region, time zone, device pool, etc., in the Cisco CallManager MIB, get populated only if the local Real-Time Information Server (RIS) data collector is up and running.

Configuring the Cisco CallManager Traps
This section describes how to configure Cisco CallManager SNMP traps.
Note Make sure to start the SNMP service before you configure traps. Refer to the "Starting the Cisco CallManager SNMP Extension Agent" section to start SNMP. Also, make sure that you have configured the SNMP READ-WRITE community name correctly. Refer to the "Configuring SNMP Security" section.
The CISCO-CCM-MIB supports the following traps:
•ccmCallManagerFailed
•ccmPhoneFailed
•ccmPhoneStatusUpdate
•ccmGatewayFailed
•ccmMediaResourceListExhausted
•ccmRouteListExhausted
•ccmGatewayLayer2Change
The "ccmAlarmConfigInfo" group in the CISCO-CCM-MIB defines the configuration parameters that are related to these traps. Refer to the CISCO-CCM-MIB document for more details about these configuration parameters. Access the CISCO-CCM-MIB at the following link:
ftp://ftp.cisco.com/pub/mibs/supportlists1/callmanager/callmanager-supportlist.html
Table 28-1 comprises information about how to configure Cisco CallManager trap parameters.
Note Some changes in the default values for some parameters in the ccmAlarmConfigInfo group in the CCM MIB occurred since the earlier releases of Cisco CallManager. Refer to the CISCO-CCM-MIB for more details

Stopping the Cisco CallManager SNMP Extension Agent
This section describes how to stop the Cisco CallManager SNMP extension agent.
Caution Stopping the SNMP service results in loss of data; the network management system no longer monitors the Cisco CallManager network.
Do not stop the service except in an emergency.
Procedure
Step 1 Choose Start > Settings > Control Panel.
Step 2 Double-click Administrative Tools.
Step 3 Double-click Services.
Step 4 Right-click SNMP Service.
Step 5 From the toolbar, choose Stop Service.
The SNMP Service stops, and the Cisco CallManager SNMP extension agent no longer functions.

Understanding Cisco Real-Time Information Server Data Collector
Cisco Real-Time Information Server (RIS) data collector runs on Microsoft Windows 2000 and has responsibility for sending the configured information from the Cisco CallManager database into the RIS database. Cisco CallManager sends all the dynamic information to the RIS database through the alarm interface.
Starting the Cisco RIS Data Collector
This section describes how to start the Cisco RIS data collector.
Note The Cisco RIS data collector service should start automatically when the system boots. Start the Cisco RIS data collector service only if it does not start automatically.
Procedure
Step 1 Choose Start > Settings > Control Panel.
Step 2 Double-click Administrative Tools.
Step 3 Double-click Services.
Step 4 Choose Cisco RIS DC Service.
Step 5 From the toolbar, choose Start Service.
The Cisco RIS data collector service starts, and all the static tables in the CISCO-CCM-MIB get populated with configuration data from the Cisco CallManager database.
Note The dynamic tables such as phoneTable, gatewayTable, etc., get populated only if the local Cisco CallManager service is up and running.

Stopping Cisco RIS Data Collector
This section describes how to stop the Cisco RIS data collector.
Caution Stopping the Cisco RIS data collector service results in loss of static information in the CISCO-CCM-MIB.
Do not stop the service except in an emergency.
Procedure
Step 1 Choose Start > Settings > Control Panel.
Step 2 Double-click Administrative Tools.
Step 3 Double-click Services.
Step 4 Choose Cisco RIS DC Service.
Step 5 From the toolbar, choose Stop Service.
The Cisco RIS data collector service stops, and the Cisco CallManager SNMP extension agent loses the static information in the CCM MIB; the dynamic tables will still contain valid data as long as the local Cisco CallManager service is running.

Updating the CISCO-CCM-MIB Information
The CISCO-CCM-MIB contains both dynamic and configured (static) information that is related to a Cisco CallManager system. At startup, the Cisco RIS data collector service updates the RIS database with all the configured information from the Cisco CallManager database. It also updates the RIS static data when configuration data changes occur in the Cisco CallManager database. When the status of a device changes, Cisco CallManager sends all the dynamic information to the RIS database through the alarm interface.
