• When you change the VCS configuration (VCS mode, RBridge ID, or VCS ID), the configuration
change is synchronized with the standby management module and saved persistently. This event
triggers a chassis reboot after the synchronization is complete.
• When you initiate a firmware download. Refer to
on page 101 for more
information.
Managing configurations in Brocade VCS Fabric mode
With the exception of a few parameters, configuration changes you make to a single switch in a
Brocade VCS Fabric are not automatically distributed. When configuring Ethernet fabric parameters
and software features on multiple switches, you must configure each switch individually. To simplify
the procedure, you can upload a configuration file from one switch and download it to the other
switches in the fabric, provided the switches are of the same type.
NOTE
The switches must be of the same model to share a configuration file. For example, downloading a
configuration file from a Brocade VDX 6720-24 to a Brocade VDX 6720-60 or to a switch with a
different firmware version may cause the switch to misapply the configuration and lead to
unpredictable behavior.
To determine the switch type, issue the show system command. To map the switch type to the
Brocade switch model name, refer to
If you need to reset affected switches, restore the default configuration as described in
on page 106.
Automatic distribution of configuration parameters
A few configuration parameters are fabric-wide in fabric cluster mode. This means they are
automatically distributed to all switches in a VCS fabric when you configure one or more of these
parameters on a single RBridge that is part of a VCS fabric. These parameters include the following:
• Zoning configuration
• vCenter parameters
• Virtual IP address
NOTE
In logical chassis cluster mode, all configuration is automatically distributed.
The show running configuration command displays the same configuration for these features on all
RBridges in the VCS fabric. Copy operations from any RBridge include all fabric-wide configuration
parameters.
Downloading a configuration to multiple switches
NOTE
This section does not apply to logical chassis cluster mode because, in that mode, configuration is
automatically distributed.
