Port Numbering Convention

Port Numbering Convention

The following port numbering convention is used for the Fabric Extender:
interface ethernet chassis/slot/QSFP-module/port
where
• chassis is configured by the administrator. A Fabric Extender must be directly connected to its parent
• slot identifies the slot number on the Fabric Extender.
• QSFP-module identifies the 10G breakout Linecard Expansion Module (LEM).
• port identifies the port number on a specific slot and chassis ID.

Fabric Extender Image Management

No software ships with the Cisco Nexus 2000 Series Fabric Extender. The Fabric Extender image is bundled
into the system image of the parent switch. The image is automatically verified and updated (if required)
during the association process between the parent switch and the Fabric Extender.
When you enter the install all command, it upgrades the software on the parent Cisco Nexus Series switch
and also upgrades the software on any attached Fabric Extender. To minimize downtime as much as possible,
the Fabric Extender remains online while the installation process loads its new software image. Once the
software image has successfully loaded, the parent switch and the Fabric Extender both automatically reboot.
This process is required to maintain version compatibility between the parent switch and the Fabric Extender.

Fabric Extender Hardware

The Cisco Nexus 2000 Series Fabric Extender architecture allows hardware configurations with various host
interface counts and speeds.

160
Cisco Nexus Series device via individual fabric interfaces or a port channel fabric interface. You configure
a chassis ID on a physical Ethernet interface or port channel on the switch to identify the Fabric Extender
that is discovered through those interfaces.
The chassis ID ranges from 100 to 199.
The chassis ID is required only to access a host interface on the Fabric Extender. A
Note
value of less than 100 indicates a slot on the parent switch. The following port numbering
convention is used for the interfaces on the switch:
interface ethernet slot/port
