Maintenance and Management Features
• Access Control
You can specify the service(s) and computer IP address(es) to control access to the switch
for management.
• 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.
• Configuration and Firmware Maintenance
You can backup or restore the switch configuration or upgrade the firmware on the
switch.

through this port.
