How to Work with SNMP Users


Configuring an SNMP User

Before You Begin

Review the SNMP configuration checklist.


Procedure

1. Perform one or more of the following actions:

If you want to: Action

Add a new SNMP user

  1. Click Add New

Modify an existing SNMP user

  1. Locate the user.
  2. Click the name of the SNMP user that you want to edit.

2. Enter the configuration settings for V3

Field Description

Server

This setting displays as read only because you already specified the server.

User Name

In the field, enter the name of the user for which you want to provide access. The name can contain up to 32 characters and can contain any combination of alphanumeric characters, hyphens (-), and underscore characters (_).

Tip: Enter users that you have already configured for the network management system (NMS).


For existing SNMP users, this setting displays as read only.

Authentication Required

Check to require authentication, then enter the password in the Password and Reenter Password fields, and select the appropriate protocol. The password must contain at least 8 characters.

Privacy Required

If you checked Authentication Required, you can specify privacy information. Check to require privacy, and then enter the password in the Password and Reenter Password fields, and check Protocol. The password must contain at least eight characters.

Tip: After you check Privacy Required, the DES (Data Encryption Standard) check box automatically appears checked. The DES protocol prevents packets from being disclosed.

Accept SNMP Packets from any host

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

Accept SNMP Packets only from these hosts

To accept SNMP packets from specific hosts, click the radio button. In the Host IP Address field, enter a host from which you want to accept SNMP packets and click Insert. Repeat this process for each host from which you want to accept SNMP packets. To delete a host, select that Host from the Host IP Addresses pane and click Remove.

Access Privileges

From the list box, select one of the following options for the access level:

  • ReadOnly-The user can only read the values of MIB objects.
  • ReadWrite-The user can read and write the values of MIB objects.
  • ReadWriteNotify-The user can read and write the values of MIB objects and send MIB object values for a trap and inform messages.
  • NotifyOnly-The user can only send MIB object values for a trap and inform messages.
  • None-The user cannot read, write, or send trap information.


To change the trap configuration parameters, you need to configure a user with NotifyOnly or ReadWriteNotify privileges.

Apply To All Nodes

Check to apply the user configuration to all nodes in the cluster.

3. Perform one of the following actions:

  • Click Insert to add a new user.
  • Click Save to save changes to an existing user.

4. Perform one of the following actions when a message indicates that changes will not take effect until you restart the SNMP master agent:

  • Click OK to restart the SNMP master agent service.
  • Click Cancel to continue the configuration without restarting the SNMP master agent.


Troubleshooting Tips
  • We recommend that you wait until you finish the SNMP configuration before you restart the SNMP master agent service.
  • To access this Cisco Unified Communications Manager server that has the user that you configure, make sure that you configure this user on the NMS with the appropriate authentication and privacy settings.
  • You can click Clear All at any time to delete all information that you entered for all settings.
