SNMP Template
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.
Use the SNMP template to configure the SNMP agent and trap receivers.
-
To enable SNMP on the appliance, select the Enable SNMP check box. Additional areas on the template 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
Configure 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 SNMP 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.
