Setup SNMP Credentials for Cisco Unity Connection

SNMP Management Information Base (MIB) interface is used to collect certain data metrics. In order to access this MIB data in a Cisco Unity Connection (CUC) environment, it is necessary to set the SNMP credentials in the Cisco Unified Serviceability page of the CUC Administration Console.

Depending upon the SNMP version being used, the SNMP Agent provides access security by using Community Strings or Username/Passwords. In order to obtain MIB data, these credentials must be set up with at least Read access rights. This is done by using the following procedure.

SNMP V1/2C Credentials

From the Setup Cisco Unity Connection.

Open the Cisco Unified Serviceability page.

From the home page go to the Navigation box in the top right corner, select the 'Cisco Unified Serviceability' option and then click the Go button.

From the menu panel select:

Snmp → V1/V2c → Community String

This will open the 'SNMP Community String Configuration' page.

From the Server drop-down list box, choose the server for which a community string is to be configured then select the Find button.

The Search Results panel at the bottom of the page will show any community string Names that have already been set up on the selected server.

If an existing community string is to be used, it will be necessary to ensure that the same name exists on all nodes in the cluster. If it does not, it will need to be added to each node.

To add a new community string, click the Add New button to open the input page.

In the Community String Name field, 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 (_).

The community string name must match the Community String field in the Monitoring Server configuration.

It is recommended to leave the 'Host IP Addresses Information' section at the default setting of 'Accept SNMP Packets from any host'.

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

ReadOnly

Community string can only read the values of MIB objects.

ReadWrite

Community string can read and write the values of MIB objects.

ReadWriteNotify

Community string can read and write the values of MIB objects and send MIB object values for a trap and inform messages.

ReadNotifyOnly

Community string can read values of MIB objects and also send the values for trap and inform messages.

Access Privileges must not be set to either of the following:

NotifyOnly

Community string can only send MIB object values for a trap and inform messages.

None

Community string cannot read, write, or send trap information.

The same community string must be applied to all nodes in the cluster, to do this tick the Apply To All Nodes checkbox.

The SNMP community string must be set the same for all Publishers and Subscribers in the cluster.

When finished click the Save button.

A message will indicate that changes will not take effect until the SNMP master agent is restarted. To restart the SNMP master agent service, click OK.

SNMP V3 Credentials

From the Setup Cisco Unity Connection.

Open the Cisco Unified Serviceability page.

From the home page go to the Navigation box in the top right corner, select the 'Cisco Unified Serviceability' option and then click the Go button.

From the menu bar select:

Snmp → V3 → User

This will open the ‘SNMP User Configuration’ page.

From the Server drop-down list box, choose the server for which a user is to be configured and then select the Find button. The Search Results panel at the bottom of the page will show any user that has already been set up on the selected server.

If an existing user is to be used, it will be necessary to ensure that the same user exists on all nodes in the cluster. If it does not, it will need to be added to each node.

To add a new user, click the Add New button to open the input page.

Complete the following details:

In the User Name field, enter a new user name.

If authentication is required, check the box ‘Authentication Required’ and enter the password (at least 8 characters). Also, select the protocol to be used.

If encryption is required, check the box ‘Privacy Information’ and enter the password (at least 8 characters). Also, select the protocol to be used.

The user name, authentication protocol, authentication password, encryption protocol and encryption password must match the SNMP fields in the Monitoring Server configuration. Both the authentication and encryption passwords must be 8 characters or more in length. For details see Monitoring Server Configuration for Cisco Unified Communications Manager.

It is recommended to leave the 'Host IP Addresses Information' section at the default setting of 'Accept SNMP Packets from any host'.

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

ReadOnly

User can only read the values of MIB objects.

ReadWrite

User can read and write the values of MIB objects.

ReadWriteNotify

User can read and write the values of MIB objects and send MIB object values for a trap and inform messages.

ReadNotifyOnly

User can read values of MIB objects and also send the values for trap and inform messages.

Access Privileges must not be set to either of the following:

NotifyOnly

User can only send MIB object values for a trap and inform messages.

None

User cannot read, write, or send trap information.

When finished click the Save button.

A message will indicate that changes will not take effect until the SNMP master agent is restarted. To restart the SNMP master agent service, click OK.
