You also need to change passwords from their default values and set the time and date, either via
NTP or manually.
In order to retain the changes made during configuration you will have to copy the running
configuration file to the startup configuration file. This will ensure that the chassis reboots to your
preferred configuration.
The configuration information is mirrored to the standby management module, which allows the
current configuration to remain available even if the active management module fails. The
configuration information for the Brocade VDX 8770-8 is stored in the CID cards and the flash
memory of the management modules. The configuration can be backed up to a workstation
(uploaded) and then downloaded to the active management module if necessary.
By default, the Brocade VDX 8770-8 is in VCS™ mode. It cannot be configured in standalone mode.
Without a VCS license, the chassis can be part of a two-node cluster. To be part of a larger cluster,
you must install a VCS license.
In VCS mode, the switch is part of an Ethernet fabric involving two or more VCS-enabled switches.
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 switch in the fabric. Distributed intelligence has three major characteristics:
•
The fabric is self-forming. When two or more VCS-enabled switches with unique rbridge-ids are
connected, the fabric is automatically created and the switches discover the common fabric
configuration.
•
The fabric is masterless. No single switch stores configuration information or controls fabric
operations. Any switch 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
switch. There are three major characteristics to logical chassis:
•
Each physical switch in the fabric can be managed as if it were a module in a chassis. When a
VCS-enabled switch 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 switch.
•
You can manage the edge switches in the fabric as if they were a single switch.
Establishing a serial connection to the Brocade VDX 8770-8
The serial port is located on the port side of the Brocade VDX 8770-8. The switch uses an RJ-45
connector for the serial port. An RJ-45 to DB9 adaptor is also provided with the Brocade VDX
8770-8
. The cable supplied with the switch is a rollover cable. The serial port is used to connect
to a workstation to configure the Brocade VDX 8770-8 IP address before connecting the switch to a
fabric or IP network.
NOTE
To protect the serial port from damage, keep the cover on the port when not in use.
