Usage Guidelines

Usage Scenario

To configure features in a specified version, run the snmp-agent sys-info version command to set an SNMP version.

SNMP of each version supports various access control functions:

SNMPv1:

Community-name-based access control
MIB-view-based access control

SNMPv2c:

Community-name-based access control
MIB-view-based access control
Supporting Inform messages

Besides inheriting basic SNMPv2c operations, SNMPv3 defines a management architecture, which introduces a User-based Security Model (USM) to provide users with a more secure access mechanism.

User group
Group-based access control
User-based access control
Authentication and encryption mechanisms
Supporting Inform messages

Run the display snmp-agent sys-info command to view system maintenance information, such as the node physical location and SNMP version.

Configuration Impact

Running the undo snmp-agent command cause configuration of all SNMP versions (SNMPv1, SNMPv2c, and SNMPv3) on the device to become invalid.

Precautions

SNMPv1 and SNMPv2c have security risks. Using SNMPv3 is recommended.

Example

# Set the current SNMP version to v3.
