This tab summarizes the SNMP configuration for each of the selected appliances.

SNMP Overview

EdgeConnect appliances support Management Information Base (MIB-II) as described in RFC 1213 for cold start traps, warm start traps, and EdgeConnect private MIBs. Appliances issue an SNMP trap during reset when loading a new image, recovering from a crash, or rebooting.

An appliance sends a trap every time an alarm is raised or cleared. Traps contain additional information about alarms, including severity, sequence number, a text-based description of the alarm, and the time the alarm was created. For more information, you can download a .zip archive containing supported MIBs here.

Modify SNMP Configuration

To modify the SNMP configuration, click the Edit icon to the left of an appliance row.

Use this page to configure the appliance’s SNMP agent and trap receivers.

To activate configuration options for SNMP v1/v2, SNMP v3, and Trap Receivers details, select the Enable SNMP check box.
If you select the Enable SNMP Traps check box, the SNMP agent on the appliance sends traps to configured receivers.
Use the Default Trap Community field to specify the string the trap receiver uses to accept traps being sent to it. The default value is public. You can modify this value.

SNMP v1/v2

Configure the following fields for SNMP v1 and v2c.

Field	Description
Enable SNMP	Allows the SNMP agent on the appliance to send traps to configured receivers.
Read-Only Community	The SNMP application needs to present this text string (secret) to poll the appliance’s SNMP agent. The default value is public. You can modify this value.

SNMP v3

For additional security, configure SNMP v3 if you want to authenticate without using clear text. To add an SNMP v3 user, click Add above the SNMP v3 table and configure the following properties:

Field	Description
Enabled	Select this check box to enable the selected user. Clear this check box to disable the user and maintain the configuration.
Username	Enter the username to identify the SNMP v3 user.
Authentication Type	Select the authentication type to use for SNMP requests from the user. NOTE: Authentication type is required and SHA-1 is the only supported algorithm.
Authentication Password	Enter a password that the SNMP agent can use to authenticate requests sent by the user. NOTE: The password must be at least 20 characters long.
Privacy Type	Select the encryption type to use for encrypting requests from the SNMP user. NOTE: Encryption is required, and AES-128 is the only supported algorithm.
Privacy Password	Enter a password (key) to use for encrypting requests sent by the user. NOTE: The password must be at least 20 characters long.

To delete an SNMP v3 user, click the X to the right of the entry in the table.

Trap Receivers

To configure a trap receiver, click Add above the Trap Receivers table and configure the following properties:

NOTE: You can configure up to three trap receivers per appliance.

Field	Description
Host	IP address of the host where traps should be sent.
Version	Select the SNMP version of the trap receiver.
Community/Username	For v1 and v2c, enter the community string the receiver should use to accept traps. If left blank, the default community string (public) is used. If a different community string is configured on the trap receiver, enter it here. For v3, specify the SNMP v3 user that is sending traps to the receiver.
Enabled	Select this check box to enable the receiver. Clear this check box to disable the receiver and maintain the configuration.

To delete a receiver, click the X to the right of the entry in the table.
