5.4.1 Configuring SNMP Support
The Simple Network Management Protocol (SNMP) system consists of three parts: an SNMP manager, an SNMP agent, and a Management Information Base (MIB). SNMP is an
The SNMP agent gathers data from the MIB, which holds the information about device parameters and network data. The agent also responds to the manager’s requests to get or set data. An agent can also send unsolicited traps to the manager. Traps are messages alerting the SNMP manager to a specific event on the network. Such events include improper user authentication, restarts, link status (up or down), closing of a TCP connection, or loss of connection to a neighboring switch. An SNMP manager can request a value from an agent, or store or change a value in that agent.
To configure support for SNMP on the switch, perform the following tasks:
•Create an SNMP user group

Switch(Config)# snmp group add read_grp version 1 access ro | Create a ‘read_only’ version 1group |
| ‘read_grp’ |

Command | Purpose |
|
|
Switch(Config)# snmp user add user_read group read_grp version 1 | Create a version 1 user ‘user_read’ of |
| group ‘read_grp’ |
