The Cisco Nexus B22 Fabric Extender for Dell is managed by its parent Cisco Nexus switch over the
fabric interfaces through a zero-touch configuration model. You upgrade the Fabric Extender by
upgrading the software on the parent Cisco Nexus switch.
When a Fabric Extender is properly associated with a parent switch, the following upgrade operations
are performed:
•
The switch checks the software image compatibility and upgrades the Fabric Extender if necessary.
•
The switch pushes the configuration data to the fabric extender. The Fabric Extender does not store
any configuration locally.
•
The Fabric Extender updates the switch with its operational status. All fabric extender information
is displayed using the switch commands for monitoring and troubleshooting.
In-Service Software Upgrades (ISSUs) are supported on the parent Cisco Nexus switches. An ISSU can
update the software images on your device without disrupting data traffic. An ISSU updates the
Kickstart, System, and Fabric Extender image.
The
install all
command triggers the ISSU on the parent Cisco Nexus switches and the Cisco Nexus B22
Fabric Extender for Dell. The command provides the following benefits:
•
You can upgrade the parent Cisco Nexus switches and the Cisco Nexus B22 Fabric Extender for Dell
using just one command.
•
You can receive descriptive information about the intended changes to your system before you
continue with the installation. For example, it identifies potential disruptive upgrades.
