Configuration Backup &
Restoration
Make a copy of the Switch’s configuration and put it back on the Switch
later if you decide you want to revert back to an earl i er configuration.
Cluster Management Cluster management (also known as iStacking) allows you to manage
switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be
able to communicate with one another.
