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
Setting the date and time
The Brocade VDX 6730 maintains the current date and time inside a battery-backed real-time
clock (RTC) circuit. Date and time are used for logging events. Switch operation does not depend on
the date and time; a Brocade VDX 6730 with an incorrect date and time value functions properly.
Because the date and time are used for logging, error detection, and troubleshooting, you should
set them correctly.
Understanding time zones
You can set the time zone for a switch by using the clock TimeZone command. The time zone
setting has the following characteristics:
20
The switch reboots when you confirm that you want to enable VCS mode.
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 VDX 6730 is 1.
Change the VCS ID if you need to create a new, separate VCS fabric.
