Tip If you use SNMP version 3, see the "SNMP V3 Configuration" section on page 16-1.


Finding a Community String


Tip The Add New button does not display in the SNMP Community String Configuration window until you click the Find button. If no community strings exist and you want to add want a community string, click the Find button and wait for the window to refresh. The Add New button displays.


To find a community string, perform the following procedure:

Procedure


Step 1 Choose Snmp > V1/V2c > Community String.

The Find/List window displays.

Step 2 From the Find Community Strings where Name drop-down list box, choose the specific search criteria that you want to use for the community string.

Step 3 Enter the community string for which you want to search.

Step 4 In the Server field, enter the hostname or IP address of the server where the community string exists.

Step 5 Click Find.

After you click the Find button, the Add New button displays. After the search results display, the Apply to All Nodes check box displays.

Step 6 If you want to apply the configuration from one of the options in the search results to all nodes in the cluster, check the check box next to the name of the option and check the Apply to All Nodes check box.

Step 7 From the list of results, click the community string that you want to view.

Step 8 To add or update a community string, see the "Configuring a Community String" section.


Additional Information

See the "Related Topics" section.

Configuring a Community String

Because the SNMP agent provides security by using community strings, you must configure the community string to access any management information base (MIB) in a Cisco Unified CallManager system. Change the community string to limit access to the Cisco Unified CallManager system. To add, modify, and delete community strings, access the SNMP Community String configuration window.

Procedure


Step 1 Perform the procedure in the "Finding a Community String" section.

Step 2 Perform one of the following tasks:

To add a new community string, click the Add New button and go to Step 3.

To modify an existing community string, locate the community string, as described in the "Finding a Community String" section; click the name of the community string that you want to edit and go to Step 3.

You cannot change the name of the community string or the server for the community string.

To delete a community string, see the "Deleting a Community String" section.

Step 3 Enter the configuration settings, as described in Table 15-1.


Tip If you are adding a new community string, you can click the Clear All button at any time to delete all information that you entered for all settings.


Step 4 After you complete the configuration, click Add New to save a new community string or click Save to save changes to an existing community string.

Step 5 A message indicates that changes will not take effect until you restart the SNMP master agent. To continue the configuration without restarting the SNMP master agent, click Cancel. To restart the SNMP master agent service, click OK.


Note Cisco recommends that you wait until you finish all the SNMP configuration before you restart the SNMP master agent service. For information on how to restart the service, see the "Starting, Stopping, Restarting, and Refreshing Status of Services in Control Center" section on page 2-2.


The system refreshes and displays the SNMP Community String Configuration window. The community string that you created displays in the window.

Community String Configuration Settings

Table 15-1 describes the community string configuration settings. For related procedures, see the "Related Topics" section.

Table 15-1 Community String Configuration Settings 

Field
Description

Server

This setting in the Community String configuration window displays as read only because you specified the server choice when you performed the procedure in the "Finding a Community String" section.

To change the server for the community string, perform the procedure in the "Finding a Community String" section.

Community String

Enter a name for the community string. The name can contain up to 32 characters and can contain any combination of alphanumeric characters, hyphens (-), and underscore characters (_).

Tip Choose community string names that will be hard for outsiders to figure out.

When you edit a community string, you cannot change the name of the community string.

Accept SNMP Packets from any host

To accept SNMP packets from any host, click this radio button.

Accept SNMP Packets only from these hosts

To accept SNMP only from specified hosts, click this radio button.

Tip In the Host IP Address field, enter a host from which you want to accept packets and click Insert. Repeat this process for each host from which you want to accept packets. To delete a host, choose that host from the Host IP Addresses list box and click Remove.

Access Privileges

From the drop-down list box, choose the appropriate access level from the following list:

ReadOnly—The community string can only read the values of MIB objects.

ReadWrite—The community string can read and write the values of MIB objects.

ReadWriteNotify—The community string can read and write the values of MIB objects and send MIB object values for a trap and inform messages.

NotifyOnly—The community string can only send MIB object values for a trap and inform messages.

None—The community string cannot read, write, or send trap information.

Tip To change the Cisco Unified Presence trap configuration parameters, you need to use a community with NotifyOnly or ReadWriteNotify privileges.

Apply To All Nodes

To apply the community string to all nodes in the cluster, check this check box.


Deleting a Community String

To delete a community string, perform the following procedure:

Procedure


Step 1 Locate the community string, as described in the "Finding a Community String" section.

Step 2 From the list of matching records, check the check box next to the community string that you want to delete.

Step 3 Click Delete Selected.

Step 4 A message indicates that the system will delete notification entries that relate to this community string. To continue the deletion, click OK.

Step 5 A message indicates that changes will not take effect until you restart the SNMP master agent. To continue the configuration without restarting the SNMP master agent, click Cancel. To restart the SNMP master agent service, click OK.


Tip Cisco recommends that you wait until you finish all the SNMP configuration before you restart the SNMP master agent service. For information on how to restart the service, see the "Starting, Stopping, Restarting, and Refreshing Status of Services in Control Center" section on page 2-2.


After the window refreshes, the string that you deleted no longer displays in the results.
