Send documentation comments to [email protected] 33 C H A P T E R Configuring SNMP The CLI and SNMP use common roles in all switches in the Cisco MDS 9000 Family. You can use SNMP to modify a role that was created using the CLI and vice versa. Users, passwords, and roles for all CLI and SNMP users are the same. A user configured through the CLI can access the switch using SNMP (for example, the Fabric Manager or the Device Manager) and vice versa. This chapter includes the following sections: • About SNMP Security, page 33-1 • SNMPv3 CLI User Management and AAA Integration, page 33-3 • Creating and Modifying Users, page 33-4 • SNMP Trap and Inform Notifications, page 33-8 • Default Settings, page 33-18 About SNMP Security SNMP is an application layer protocol that facilitates the exchange of management information between network devices. In all Cisco MDS 9000 Family switches, three SNMP versions are available: SNMPv1, SNMPv2c, and SNMPv3 (see Figure 33-1).
