SNMP

The Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing devices on IP networks.

It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects. SNMP exposes management data in the form of variables on the managed systems, which describe the system configuration. These variables can then be queried (and sometimes set) by managing applications.

In the System ➤ SNMP Page, you can configure SNMP V2c and SNMP V3.

SNMP Information

In the SNMP Information section, the text fields for the SNMP Enterprise ID, Contact, and Location information are shown.

SNMP Configuration

General Settings

CpxWRT System SNMP.png

Enable SNMP: Enables SNMP.
SNMP V2c Read Password: Sets the community string for read-only access (to the variables on the SNMP agent) by the network management station (NMS). The NMS is the software which runs on the SNMP manager. (default: public)

SNMP V2c Write Password: Sets the community string for read-write access by the SNMP manager. (default: private) A community string identifies a group of SNMP agents. It is sent in clear text. It should be changed from the default string “public” or “private”. The variables on the SNMP agent can be classified into read-only or read-write variables.

SNMP V3 Username: Sets the username for authentication. (default: admin)

SNMP V3 Auth Algorithm: Shows the authentication algorithm used e.g. MD5.

SNMP V3 Auth Password: Configures the password for user authentication. (default: password)

SNMP V3 Privacy Algorithm: Shows the data encryption algorithm used e.g. DES.

SNMP V3 Privacy Password: Sets the password for data encryption. (default: password)

Trap
