Backing up and restoring switch configurations

Backing up and restoring a configuration is useful to protect your work or for use as a template in configuring other switches. The Config Backup command creates a file on the switch, named configdata. This file can be used to restore a switch configuration only from the CLI; it cannot be used to restore a switch using McDATA Web Server.

McDATA4GbSAN #> admin start

McDATA4GbSAN (admin) #> config backup

The configdata file contains all of the switch configuration information including the following:

•All named switch configurations including the default configuration. This includes port, switch, port threshold alarm, and zoning configuration components.

•All SNMP and network information defined with the Set Setup command.•The zoning database included all zone sets, zones, and aliases

You use FTP to download the configdata file to your workstation for safe keeping and to upload the file back to the switch for the restore function. To download the configdata file, open an FTP session on the switch and log in with the account name “images” and password “images”. Transfer the file in binary mode with the Get command as shown:

>ftp ip_address

user:images

password: images

ftp>bin

ftp>get configdata

xxxxxbytes sent in xx secs.

ftp>quit

You should rename the configdata file on your workstation with the switch name and date, config_switch_169_10112003, for example.

The restore operation begins with FTP to upload the configuration file from the workstation to the switch, then finishes with a Telnet session and the Config Restore command. To upload the configuration file, config_switch_169_10112003 in this case, open and FTP session with account name “images” and password “images”. Transfer the file in binary mode with the Put command as shown:

ftp ip_address user:images password: images ftp> bin

ftp> put config_switch_169_10112003 configdata Local file config_switch_169_10112003 Remote file configdata

ftp>quit

The restore process replaces all configuration information on the switch and afterwards the switch is automatically reset. All management sessions are lost because the switch is reset. Use the Set Setup System command to return the IP configuration to the values you want. Refer to the ”Show Setup command” on page 196. To restore the switch, open a Telnet session, then enter the Config Restore command from within an Admin session as shown:

McDATA4GbSAN #> admin start

McDATA4GbSAN (admin) #> config restore

The switch will be reset after restoring the configuration.

Please confirm (y/n): [n] y

Alarm Msg: [day month date time year][A1005.0021][SM][Configuration is being restored - this could take several minutes !]

Alarm Msg: [day month date time year][A1000.000A][SM][The switch will be reset in 3 seconds due to a config restore]

McDATA4GbSAN (admin) #>

Alarm Msg: [day month date time year][A1000.0005][SM][The switch is being reset]

Good bye.
