Simple Network Management Protocol
This chapter is a reference for Simple Network Management Protocol (SNMP) commands.
SNMP provides a standardized framework and a common language for monitoring and managing devices in a network. The SNMP framework consists of three parts:
• An SNMP manager: The system used to control and monitor the activities of network devices. This is sometimes called a Network Management System (NMS).
• An SNMP agent: The component within a managed device that maintains the data for the device and reports these data SNMP managers.
• Management Information Base (MIB): SNMP exposes management data in the form of variables which describe the system configuration. These variables can be queried by SNMP managers.
In SNMP, administration groups are known as communities. SNMP communities consist of one agent and one or more SNMP managers. You can assign groups of hosts to SNMP communities for limited security checking of agents and management systems or for administrative purposes. Defining communities provides security by allowing only management systems and agents within the same community to communicate.
A host can belong to multiple communities at the same time, but an agent does not accept a request from a management system outside its list of acceptable community names.
SNMP access rights are organized by groups. Each group is defined with three accesses: read access, write access, and notification access. Each access can be enabled or disabled within each group.
The SNMP v3 security level determines if an SNMP message needs to be protected from disclosure and if the message needs to be authenticated. The security levels are:
• noAuthNoPriv: No authentication or encryption
• authNoPriv: Authentication but no encryption
• authPriv: Both authentication and encryption.
SNMP is defined in RFCs 3411-3418.
Note: The commands below are supported on the “management” and default VRF.
