∙
The fabric is self-forming. When two VCS-enabled devices are connected, the VCS fabric is automatically created and the
devices discover the common fabric configuration.
∙
The fabric is masterless. No single device stores configuration information or controls fabric operations. Any device can fail or
be removed without causing disruptive fabric downtime or delayed traffic.
∙
The fabric is aware of all members, devices, and Virtual Machines (VMs). Automatic Migration of Port Profiles (AMPP) supports
VM migration to another physical server. If the VM moves, it is automatically reconnected to all of its original resources.
Logical chassis means that the entire VCS fabric appears and can be managed as a single Layer 2 device. There are three major
characteristics to logical chassis:
∙
Each physical device in the fabric can be managed as if it were a blade in a chassis. When a VCS-enabled device is connected
to the fabric, it inherits the configuration of the fabric and the new ports become available immediately.
∙
You can manage the entire fabric from any device.
∙
You can manage the edge devices in the fabric as if they were a single device.
If necessary you can change the VCS ID for the device using the vcs vcsid command, where the vcsid is a value from 1 to 8192. By
default, the device VCS ID is 1. Change the VCS ID if you need to create a new, separate VCS fabric.
In order to retain the changes made during configuration, you must copy the running configuration file to the startup configuration file
using the copy running-config startup-config command. This will ensure that the device reboots to your preferred configuration.
Configuration tasks
