Setting the SNMP Configuration

1. Select the SNMP tab.
   

   
2. Enable or disable SNMP v1, SNMPv2 and SNMPv3.

   Enable SNMPv1	SNMP v1exposes a device‘s management data so it can be managed remotely. Device data is exposed as variables that can be accessed and modified as text strings, with version 1 being the original (rudimentary) implementation. SNMPv1 is enabled by default.
   Enable SNMPv2	Select the checkbox to enable SNMPv2 support. SNMPv2 provides device management using a hierarchical set of variables. SNMPv2 uses Get, GetNext, and Set operations for data management. SNMPv2 is enabled by default.
   Enable SNMPv3	Select the checkbox to enable SNMPv3 support. SNMPv3 adds security and remote configuration capabilities to previous versions. The SNMPv3 architecture introduces the user-based security model (USM) for message security and the view-based access control model (VACM) for access control. The architecture supports the concurrent use of different security, access control and message processing techniques. SNMPv3 is enabled by default.

3. Set the SNMP v1/v2 Community String configuration. Use the + Add Row function as needed to add additional SNMP v1/2 community strings, or select an existing community string‘s radio button and select the Delete icon to remove it.

   Community	Define a public or private community designation. By default, SNMPv2 community strings on most devices are set to public, for the read-only community string, and private for the read-write community string.
   Access Control	Set the access permission for each community string used by devices to retrieve or modify information. Available options include: Read Only - Allows a remote device to retrieve information. Read-Write - Allows a remote device to modify settings.
   IP SNMP ACL	Set the IP SNMP ACL used along with community string. Use the dropdown menu to select an existing ACL. Use the Create icon to create and add a new ACL. Select an existing ACL and the Edit icon to update an existing ACL.

4. Set the SNMPv3 Users configuration. Use the + Add Row function as needed to add additional SNMPv3 user configurations, or select a SNMP user and select the Delete icon to remove the user.

   User Name	Use the drop-down menu to define a user name of snmpmanager, snmpoperator or snmptrap.
   Authentication	Displays the authentication scheme used with the listed SNMPv3 user. The listed authentication scheme ensures only trusted and authorized users and devices can access the network.
   Encryption	Select to enable TACACS accounting on login. This option is not available when the Local field is set to enabled. When selected, the AAA TACACS Policy field is enabled.
   Password	Provide the user‘s password in the field provided. Select the Show check box to display the actual character string used in the password, while leaving the check box unselected protects the password and displays each character as “*”.

5. Select OK to update the SNMP configuration. Select Reset to revert to the last saved configuration.
