Backing Up And Restoring Over The Web Interface - 3Com SuperStack 3 3870 Getting Started Manual

downloaded at a later time to ease recovery from system errors or to help
in setting up a new Switch.
You must have read/write management access to save and restore the
system's configuration settings.
The configuration of the Switch must only be restored or saved by a
single user at a time.
The restore operation will not be successful if the physical configuration
of the device is different. The configuration settings can only be restored
onto a device of the same type (that is, a 24-port or 48-port Switch 3870
with the same optional media expansion modules) and with the same
physical connections, as when the configuration was initially saved. Also,
note that the configuration settings cannot be restored to a stack if a
new unit or expansion module has been added. Always create a new
backup file after making any physical changes to the devices in the stack.
If the configuration file contains any settings for VLANs, Spanning Tree,
or aggregated links, there is a chance that restoring these settings could
result in network loops or other problems which may bring down the
network to which the Switch is attached. If you are not sure that the
configuration settings will work properly in the current network
environment, 3Com advises you to disconnect the Switch from the
network and connect it directly to the management station before
attempting to restore the configuration settings.
Before initiating any file transfer operation over the network, perform the
following preliminary tasks:
Ping the TFTP server from the Switch's CLI using the protocol ip
■
ping command to ensure that it can be accessed from your Switch.
Configure your TFTP server by setting the upload/download directory,
■
enabling file uploads, and enabling overwriting of existing files as
required.
