When the switch comes back up, if it is connected to other VCS-enabled switches, the
negotiation protocols begin, determining which switch in the fabric is the principal switch and
making sure that all domain IDs, and therefore RBridge IDs, are unique. Should the insistent
domain ID not be unique, you can change it. Once the domain IDs are determined to be
unique, they are equated to the RBridge IDs.
The switch with the lowest World Wide Name (WWN) becomes the principal switch, primarily for
purposes of determining the uniqueness of the ID of the other switches in the fabric. The WWN
is a unique identifier burned into the switch at the factory.
Another parameter that can be changed if necessary is the VCS ID. This identifies the VCS
fabric of which the switch can be a part. By default, the VCS ID of every Brocade Brocade VDX
8770-4 is 1. Change the VCS ID if you need to create a new, separate VCS fabric.
3. If you need to change the VCS ID, enter the vcs vcs-id x command, where x is the new VCS ID
number.
4. Enter the copy running-config startup-config command to apply the current running
configuration to the startup configuration. This is important to capture any changes that have
been made to the running configuration so that they will persist the next time the switch
reboots in the same mode.
Perform the following steps to disable VCS mode.
1. Log in to the switch using an account that has the admin role.
2. Enter the no vcs enable command.
3. Reboot the switch.
4. When the switch comes back up, enter the copy running-config startup-config command to
apply the default configuration to the startup configuration.
This is important to capture any changes that have been made to the running configuration so
that they will persist the next time the switch reboots in the same mode.
Logging off the serial console port and disconnecting the serial cable
You can use the serial port to monitor error messages through the serial connection. If the serial
port is no longer required, use the logout command to log out of the serial console, remove the
serial cable, and replace the protective plug in the serial port.
Establishing an Ethernet connection to the Brocade VDX 8770-4
After using a serial connection to configure the IP addresses for the Brocade VDX 8770-4, you can
connect the active MM to the local area network (LAN).
NOTE
Connecting the MMs to a private network is recommended.
By establishing an Ethernet connection, you can complete the Brocade VDX 8770-4 configuration
using a serial session, Telnet, or management application, such as Brocade Network Advisor.
