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.

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,
