Configurations across a fabric

If fmsmode is enabled in a configuration file, but is disabled on the switch, the configDownload
command fails and displays an error message. This prevents undesirable conditions that could
result from enabling fmsmode on a switch that does not require it.
Configurations across a fabric
To save time when configuring fabric parameters and software features, you can save a
configuration file from one switch and download it to other switches of the same model type, as
shown in the following procedure.
Do not download a configuration file from one switch to another switch that is a different model or
firmware version, because it can cause the switch to fail. If you need to reset affected switches,
issue the configDefault command.
ATTENTION
Verify that all domain IDs are unique prior to performing the configDownload because the switches
will segment if they all have the same domain ID.
If you download an existing configuration file to a switch that has a different Interoperable mode
setting, the configDownload command will fail. You must first change the switch’s interoperable
mode to equal that of the configuration file, reboot the switch, then re-download the configuration
file.
Downloading a configuration file from one switch to another same
model switch
1. Configure one switch.
2. Use the configUpload command to save the configuration information. See “Configuration file
backup” on page 166 for more information.
