Chapter 1 Getting to Know Your Switch 32
• The switch supports IGMP snooping enabling group multicast traffic to be only
forwarded to ports that are members of that group; thus allowing you to significantly
reduce multicast traffic passing through your switch.
• Broadcast storm control
Port Authentication and Security
For security, the switch allows authentication using IEEE 802.1x with an external RADIUS
server and port security that allows only packets with dynamically learned MAC addresses
and/or configured static MAC addresses to pass through a port on the switch.
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.
