Conguration overview
• IP address and gateway address for the device
• IP addresses, host names, and gateway addresses for one or two management modules, as needed
• Passwords - You may need to change passwords from their default values and set the time and date, either by the way of NTP
or manually.
Upon bootup, the device attempts to form ISLs with connected devices. If the device is not connected to another device, it forms a
"single node VCS fabric." This means that the chassis operates as a standalone system, but the operational mode is always VCS-
enabled.
In VCS mode, the device can be part of an Ethernet fabric involving two or more VCS-enabled devices. VCS technology embodies the
concepts of distributed intelligence and logical chassis. Distributed intelligence means that all conguration and destination information is
automatically distributed to each member in the fabric. Distributed intelligence has three major characteristics:
• The fabric is self-forming. When two VCS-enabled devices are connected, the fabric is automatically created and the devices
discover the common fabric conguration.
• The fabric is masterless. No single device stores conguration information or controls fabric operations. Any device can fail or
be removed without causing disruptive fabric downtime or delayed trac.
• The fabric is aware of all members, devices, and Virtual Machines (VMs). Automatic Migration of Port Proles (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 conguration 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.
In Network OS v7.1.0 and later, all conguration changes are maintained in the running conguration after a reboot. For prior releases,
for nodes in fabric cluster mode only, you must copy the running conguration le to the startup conguration using the copy running-
cong startup-cong command to ensure that the device reboots with the preferred conguration.
