> # About Common Roles

> The CLI and SNMP in all switches in the Cisco MDS 9000 Family use common roles. You can use SNMP to modify a role that was created using the CLI and vice versa.

> Each role in SNMP is the same as a role created or modified through the CLI (see the "Information About Role-Based Authorization" topic).

> Each role can be restricted to one or more VSANs as required.

> You can create new roles or modify existing roles using SNMP or the CLI.

> - SNMP—Use the CISCO-COMMON-ROLES-MIB to configure or modify roles. Refer to the Cisco MDS 9000 Family MIB Quick Reference.
> - CLI—Use the role name command.
