Configuring SNMP settings

To configure monitoring using SNMP, go to Network > SNMP.

The MCU sends out an SNMP trap when the device is shut down or started up. The SMNP page allows you to set various parameters; when you are satisfied with the settings, click Update SNMP settings.

Note that:

System information

Field Field description Usage tips
Name

Identifies the MCU in the SNMP system MIB.

Usually you would give every device a unique name. The default setting is:
MCU

Location

The location that appears in the system MIB.

An optional field. Where you have more than one MCU, it is useful to identify where the MCU is located. The default setting is:
Unknown

Contact

The contact details that appear in the system MIB.

An optional field. The default setting is:
Unknown

Add the administrator’s email address or name to identify who to contact when there is a problem with the device. If SNMP is enabled for a port on the public network, take care with the details you provide here.

Description

A description that appears in the system MIB.

An optional field, by default this will indicate the model number of the MCU. Can be used to provide more information on the MCU.

Configured trap receivers

Field Field description Usage tips
Enable traps

Select this check box to enable the MCU to send traps.

If you do not select this check box, no traps will be sent.

Enable authentication failure trap

Select this check box to enable authentication failure traps.

You cannot select this check box unless you have selected to Enable traps above. Authentication failure traps are generated and sent to the trap receivers when someone tries to read or write a MIB value with an incorrect community string.

Trap receiver addresses 1 to 4

Enter the IP address or hostname for up to four devices that will receive both the general and the authentication failure traps.

The traps that are sent by the MCU for IPv4 are SNMP v1 traps. For IPv6 the MCU sends SNMP v2 traps. You can configure trap receivers or you can view the MIB using a MIB browser. You can set the UDP port number for the trap in the format <IP address>: <port number>. By default the UDP port number is 162. Note that square brackets are mandatory for IPv6 addresses.

Access control

Field Field description Usage tips
RO community

Community string/password that gives read-only access to all trap information.

Note that SNMP community strings are not secure. They are sent in plain text across the network.

It is advisable to change the community strings before enabling SNMP as the defaults are well known.

RW community

Community string/password that gives read/write access to all trap information.

Trap community

Community string/password that is sent with all traps.

Some trap receivers can filter on trap community.
