Chapter 1 Product Overview
Nexus 5000 Series Switch Software
Configuration Verification and Rollback
With the Nexus 5000 Series switch, you can verify the consistency of a configuration and the availability
of necessary hardware resources before committing the configuration. A device can be preconfigured,
and the verified configuration can be applied at a later time. Configurations also include checkpoints to
allow the switch operator to revert to a known good configuration as needed.
Role-Based Access Control
With role-based access control (RBAC), you can limit access to switch operations by assigning roles to
users. Administrators can customize access and restrict it to the users who require it.
Configuration Methods
You can configure Nexus 5000 Series switches using direct network configuration methods or web
services hosted on a Fabric Manager server.
This section includes the following topics:
