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 VDX 6730 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.
Disabling VCS 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.
Configuring switch ports
By default, the interfaces are not configured as switch ports. In order to put an interface in Layer 2 mode, use the
following command in Interface Configuration mode.
switch(conf-if-te-1/0/3)#switchport
To remove an interface from Layer 2 mode, use the following command
switch(conf-if-te-1/0/3)#no switchport
Connecting network devices
The Brocade VDX 6730 supports only Brocade-branded SFP+ optical or copper transceivers. For its GbE
connections, the Brocade VDX 6730 uses SFP+ transceivers that support either optical or Brocade-branded
direct-attach copper and optical (Laserwire) cables.
The optical SFP+ transceivers support both Short Reach (SR) and Long Reach (LR) modules. Direct-attach copper
cables support distances of 1 meter, 3 meters, and 5 meters. Direct-attach optical cables support distances of 10
meters and 20 meters.
Non-branded active twinax cables can be used, but Brocade does not support them.
