Configure SNMP

SNMP v2c can be enabled for each of the device types in the system. Enabling allows polling of any selected devices from all of the provided IP addresses. This feature allows numerous statistics to be collected by a third-party application. The following check boxes and fields are available:

Table 1. SNMP fields
Field	Description
Enable SNMP	Checking this box enables SNMP collection.
Manager, Accesser® Devices, Slicestor® Devices, File Accesser Devices	Select the device types for polling.
Community String	Configure the community string (for example, public).
IP Addresses/Subnets	Identify the IP addresses/subnets used for polling. If the IP addresses field is left blank, IP access is open, and any IP address can poll the selected devices. IP addresses can be separated by a space or comma.
Version	Specifies whether SNMPv2c or SNMPv3 will be supported.
Security Level	Specifies the security level of generated traps or informs.
Username	Specifies the username of the USM user.
Authentication Protocol	Specifies the authentication protocol of the USM user.
Authentication Password	Specifies the authentication password of the USM user.
Privacy Protocol	Specifies the privacy protocol of the USM user.
Privacy Password	Specifies the privacy password of the USM user.

Note: COS devices use the key extension algorithm defined in draft-blumenthal-aes-usm-04 when AES256 encyption is selected. Your SNMP manager may use the Reeder algorithm, defined in draft-reeder-snmpv3-usm-3desede-00, to extend keys to the required length. To poll devices or receive alerts using the Reeder algorithm, please select AES256With3DES. Refer to your SNMP manager’s documentation to determine which algorithm is required by your manager.

Changes that are made take a few minutes to take effect on each selected device.
