SNMP settings⁣⁣⁣⁣

SNMP allows the administrator to gather information about key device parameters and wireless links, including information about changes. The use of any monitoring system helps to timely receive information about the network infrastructure state using Astra devices. Currently, the devices family supports SNMP protocol versions v1 v2c and v3.

The SNMP Protocol has two branches, the agent and the management stations:

• The agent sends data to the management station. Monitoring system - provides data gathering from all agents in the network.

• The monitoring system receives and processes events.

• The information is passed through requests and replies with the use of the MIB.

• The management station or monitoring system is responsible for decoding the SNMP packets and providing an interface to the administrator.

General settings

This section allow to enable/disable SNMP protocol support.

Parameter	Description
Location	The geographical location where the unit is installed, used as a reference information about the physical device’s location.
Enabled	Enable/disable the SNMP service in the device.
Contact person	A reference information about the device owner.

SNMP v1/v2c

Parameter	Description
Enabled	Enable/disable the SNMP v.1 and v.2c support. The first version of the SNMP protocol lacks security, that hinders its use for network management, so SNMP v.1 and v.2c operates in read-only mode. Enabled by default.
Community	Set the community name for read-only mode of SNMP v.1 and v.2c, by default: "public". The community name passes along with the data packet in clear text.

SNMP v3

Due to the security level of SNMP v.3 is higher than of SNMP v.1 and v.2c, it allows not only the data collection but also to manage devices. Detailed information about the devices management via the monitoring system is available in the corresponding article.

To add an SNMP v3 user, click the corresponding button and fill in the following fields:

Parameter	Description
User name	SNMP v3 user name.
Password	SNMP v3 password.
Security	Security level: "No auth / No privacy" – the lowest security level without authentication and privacy, only Username needs to be set. This level of protection does not allow management via the monitoring system. "Auth / No privacy" – middle level with authentication but without privacy, Username and Password are required. "Auth / Privacy" – highest level with authentication and privacy, Username, Password, Privacy Password and Privacy Protocol should be set.
Readonly	Enable/disable the read-only mode, readonly is set by defaut.
Admin	Enable/disable the full access to all parameters, for example, the ability to reboot the device. By default an access is limited.
Privacy password	Set the privacy password, it is necessary when privacy is enabled for the required security level.

SNMP traps

The devices polling cycle of the monitoring system is 5 minutes. To speed up the process of detecting incidents on devices, SNMP traps can be send each time an incident occurs, regardless of the polling process.

Parameter	Description
Enable SNMP traps	Enable/disable SNMP traps sending.
Source IP address	Set the IP address of the device which sends traps

To create a new record, click the "Add SNMP Trap" button.

In the new window select the traps type to send and fill in the following parameters:

Parameter	Description
Destination address	Set the monitoring system server IP address.
Port	Set the monitoring system UDP port.
