SNMP
Administration > General Settings > Setup > SNMP
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 whenever 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. To download a .zip file of standard and proprietary MIB files you can load into the MIB browser you use, see MIB Files.
The SNMP tab lists Simple Network Management Protocol (SNMP) configuration summaries for appliances selected in the appliance tree.
| Field | Description |
|---|---|
| Appliance | Name of the appliance. |
| Enable SNMP Agent | Indicates whether the SNMP agent is enabled on the appliance. |
| Enable SNMP Traps | Indicates whether the SNMP agent on the appliance is enabled to send traps to configured receivers. |
| Enable SNMP V1/V2 | Indicates whether the SNMP agent on the appliance is enabled to send traps to configured receivers. |
| Enabled V3 Users | Indicates SNMP v3 users enabled on this appliance. |
| Trap Receiver 1 | Configuration details for the first trap receiver if configured. Up to three trap receivers can be configured. Details include the IP address of the host receiving traps, the SNMP version of the receiver, and whether the receiver is enabled. |
| Trap Receiver 2 | Configuration details for the second trap receiver if configured. |
| Trap Receiver 3 | Configuration details for the third trap receiver if configured. |
To modify the SNMP configuration for a listed appliance, click the edit icon associated with the appliance. The SNMP dialog box opens. For details, see Modify SNMP Configuration below.
NOTE: You can also use a template to manage SNMP configurations. Click the Manage SNMP with Templates link.
Click Export to save the SNMP data to a CSV file.
Modify SNMP Configuration
Use the SNMP dialog box to configure the appliance’s SNMP agent and trap receivers.
-
To enable SNMP on this appliance, select the Enable SNMP check box. Additional areas on the dialog box appear (SNMP V1/V2, SNMP V3, and Trap Receivers).
-
To enable the SNMP agent on the appliance to send traps to configured receivers, select the Enable SNMP Traps check box.
-
In the Default Trap Community field, specify the string the trap receiver should use to accept traps sent to it. The default value is “public”. You can modify this value.
-
Configure SNMP v1/v2, SNMP v3, and trap receivers, as described below.
SNMP V1/V2
Complete the following fields for SNMP v1 and v2c.
| Field | Description |
|---|---|
| Enable SNMP | Enables 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 then complete the following fields.
| Field | Description |
|---|---|
| Enabled | Select this check box to enable the selected user. Clear it 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. 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 have at least 20 characters. |
| Privacy Type | Select the encryption type to use for encrypting requests from the user. NOTE: Encryption is required. 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 have at least 20 characters. |
To remove an SNMP v3 user, click the corresponding delete icon (X) in the last column.
Trap Receivers
To configure a trap receiver, click Add above the Trap Receivers table, and then complete the following fields.
NOTE: You can configure up to three trap receivers per appliance.
| Field | Description |
|---|---|
| Host | IP address of the host to which to send traps. |
| 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 in this field. For v3, specify the SNMP v3 user sending traps to the receiver. |
| Enabled | Select this check box to enable the receiver. Clear it to disable the receiver and maintain the configuration. |
To remove a receiver, click the corresponding delete icon (X) in the last column.
