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