Configuration 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 configuration 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 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.
In Network OS v7.1.0 and later, all configuration changes are maintained in the running configuration after a reboot. For prior releases,
for nodes in fabric cluster mode only, you must copy the running configuration file to the startup configuration using the copy running-
config startup-config command to ensure that the device reboots with the preferred configuration.
