Managing SNMP notifications
Simple Network Management Protocol (SNMP) is a standard protocol for managing networks and exchanging messages. The system can send SNMP messages that notify personnel about an event. You can use an SNMP manager to view the SNMP messages that the system sends. The system supports both SNMP version 2 and version 3.
About this task
Some systems support setting up SNMP notifications for events. Event notifications are reported to the SNMP destinations of your choice. To specify an SNMP destination, you must provide a valid IP address or fully qualified domain name. If you specify a domain name, a DNS server must be configured on your system. To configure a DNS server for the system, select . You can also use the mkdnsserver command to configure DNS servers. A maximum of six SNMP destinations can be specified. For version 2 SNMP servers, the community string is required and the default value is public. You can use the Management Information Base (MIB) file for SNMP to configure a network management program to receive SNMP messages that are sent by the system. This file can be used with SNMP messages from all versions of the software. You can use your browser to download the MIB file by clicking Download MIB. The system supports both SNMP version 2 and version 3. SNMP version 3 uses the same base protocol as earlier versions, but introduces encryption and improved authentication mechanisms. Depending on how you authorize with the SNMP agent on a system, you can configure different levels of security.
Security Level | Description | Required security credentials |
---|---|---|
None | No additional authentication or encryption is used to send SNMP notifications. |
|
Authentication | Notifications are authenticated, but message content is not encrypted. |
|
Authentication and Privacy | Notifications are authenticated and message content is encrypted. |

To configure or manage SNMP servers in the management GUI, select Add SNMP Server or right-click an existing instance and select Modify.
. To configure a new server, selectFor SNMP Version 3, use a unique engine ID for every system. The system does not automatically generate the engine ID. You can use an existing engine ID from an SNMP server. If you are setting up SNMP for the first time, you must generate a new engine ID.
- SNMP will not accept any configuration get requests from SNMP server.
- Privacy Protocol AES only supports AES128.
To configure the SNMP notification settings, use the following commands:
