In this menu you can configure Simple Network Management Protocol settings.

SNMP is a simple protocol used for network monitoring and management. It allows you to collect and organizate of information about devices on TCP/IP-based networks, and can even allow you to modify that information to change device behavior.

SNMP has a simple client-server architecture. In SNMP, servers (called “managers”) collect and process information about network devices. Typically, the manager software runs on a PC or server. Clients are called “agents”. Agents run on any type of device which supports them, connected to a TCP/IP network. This can include computers, network equipment, and many other devices types, such as phones, IoT devices, and more.

SNMP allows one or more Managers to collect management data from the various clients via a regular polling process. It exposes the data in the form of variables in a database, called the Management Information Base (MIB). The MIB describes the system status and configuration of each device. MIB variables can then be remotely queried (and sometimes manipulated) by Manager applications.

Enable SNMP: Checking this enables the SNMP service, and allows a Manager program to start polling for data.

Port: Here, enter the port on which the Manager will poll data from monitored devices. (Default: 161).

Remote Access: Enabling this places a rule in the firewall exposing a UDP port (of above number) to the WAN interface. Note that SNMP is not a secure protocol. Any device that can “speak” SNMP could theoretically (query the SNMP devices or access Manager data?). For this reason, you are strongly urged to enter a setting in the Allowed Remote IP Address field described below.

Allowed Remote IP Address: In this field, enter the IP address of the PC or other device that is allowed Remote Access.

Location: In this optional field, enter the physical location of the Server. (Default: hostname from Identification menu).

Contact: In this optional field, enter contact information for a person to be alerted. FreshTomato does not have an built-in email server.

RO Community: This Read-Only Community password is used to authorize the devices allowed to query the MIB database.
