Simple Network Management Protocol (SNMP) Users Configuration on AP541N Access Point

Objective

Simple Network Management Protocol (SNMP) is a network management protocol which is used to manage network devices. It helps to record, store and share the information of various devices on the network that facilitates you to solve the network issues quickly. SNMP uses Management Information Bases (MIBs) to store the available information in a hierarchical manner.

This document explains how to configure SNMP users on AP541N Access Point. SNMP does not have any users by default.

Applicable Device

• AP541N Access Point

Software Version

• AP541N-K9-2.0(4)

SNMP Users Configuration

Step 1. Log in to the web configuration utility and choose SNMP > Users. The SNMP Users page opens:

Step 2. Enter the name of the SNMP user in the Name field. Example - user3, user4.

Step 3. Choose the group for given users from the Group drop-down list.

Note: For more information about SNMP groups, refer to the article Simple Network Management Protocol (SNMP) Groups Configuration on AP541N Access Points.

• RO — Indicates that the user in this group has no authentication and no data encryption for SNMP messages. The user has read access to the default all MIB view.

• RWAuth — Indicates that the user in this group has authentication but no data encryption for SNMP messages. The user has read and write access to the default all MIB view.

• RWPriv — Indicates that the user in this group has authentication and encryption for SNMP messages. The user has read and write access to the default all MIB view.

Step 4. Choose the authentication type from the Authentication type drop-down list to use it on SNMP requests from the SNMPv3 users. Users under RO group have no authentication.

• MD5 — Indicates that requests from SNMPv3 users require Message Digest Algorithm (MD5) authentication. MD5 uses a 128-bit hash function that produces a hash value for authentication.

• None — Indicates that no authentication is required for the SNMPv3 user requests.

Step 5. If MD5 authentication type is chosen in Step 4, enter the key in the Authentication Key field. This enables the SNMP agent to authenticate the user's request. 

Step 6. Choose the type of encryption to use on SNMPv3 requests from the Encryption type drop-down list.

Note: Users under RO and RWAuth groups do not use encryption.

• DES — Data Encryption Standard (DES) indicates the requests from the SNMPv3 users which are encrypted. DES is a widely-used method of data encryption which uses a private (secret) key.

• None — Indicates that no privacy for the SNMPv3 user requests are present.

Step 7. If DES encryption type is chosen in Step 6, enter the encryption key in the Encryption key field which ranges from 8 to 32 characters. This key is used to encrypt SNMPv3 requests.

Step 8. Click Add to add the user to the SNMPv3 Users table.

Step 9.  (Optional) To delete a user, choose one of the users from the SNMPv3 Users list and click Remove.

Step 10. Click Apply to save the settings.
