Configuration Management
All managed systems have software images and databases that must be
configured, backed up and restored. Two software images may be stored on
the system, but only one of them is active. The other one is a backup image.
The same is true for configuration files, which store the configuration
parameters for the switch. The system has three configuration files. One file is
a memory-only file and is the current configuration file for the switch. The
second file is the one that is loaded by the system when it reboots. There is
one backup configuration file. The system also provides methods to back up
these files to a remote system.
File System Commands
All files are stored in a flat file system. The commands shown in Table 2-6 are
used to perform operations on these files.
Copying Files
The copy command not only provides a method for copying files within the
file system, but also to and from remote servers. With the copy command and
URLs to identify files, the user can back up images to local or remote systems
or restore images from local or remote systems.
To use the
copy command, the user specifies the source file and the
destination file. For example, copy
tftp://remotehost/pub/backupfile backup-
config
copies a file from the remote TFTP server to a local backup
configuration file. In this case, if the local configuration file does not exist,
then it is created by the command. If it does exist, it is overwritten. If there is
not enough space on the local file system to accommodate the file, an error is
flagged.
