286 Implementing IBM System Networking 10Gb Ethernet Switches
7.1 Configuration management
This section describes how to manage configuration files, save and restore a configuration in
the switch, perform a firmware upgrade, and identify some problems by checking the system
logs and descriptions.
7.1.1 Configuration files
The switch stores its configuration in two files:
򐂰 startup-config is the configuration the switch uses when it is reloaded.
򐂰 running-config is the configuration that reflects all the changes you made from the CLI. It
is stored in memory and is lost after the reload of the switch.
7.1.2 Configuration blocks
The switch stores its configuration in one of two configuration blocks, or partitions:
򐂰 active-config is the active configuration file.
򐂰 backup-config is the alternative configuration file.
This setup has the flexibility you need to manage the configuration of the switch and perform
a possible configuration rollback.
7.1.3 Managing configuration files
This section describes the different ways of managing the configuration files.
Managing the configuration using the CLI
You can manage the configuration files by using several commands:
򐂰 Run the following command to dump the current configuration file:
Switch#show running-config
򐂰 Run the following command to copy the current (running) configuration from switch
memory to the backup-config partition:
Switch#copy running-config backup-config
򐂰 Run the following command to copy the current (running) configuration from switch
memory to the startup-config partition:
Switch#copy running-config startup-config
򐂰 Run the following command to copy the current (running) configuration from switch
memory to the active-config partition:
Switch#write memory
򐂰 Run the following command to back up the current configuration to a file on the selected
FTP/TFTP server:
Switch#copy running-config {ftp|tftp}
򐂰 Run the following command to restore the current configuration from an FTP/TFTP server.
Switch#copy {ftp|tftp} running-config
