Traffic prioritization
The switch provides a wide range of advanced performance-enhancing
features. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Broadcast storm suppression prevents broadcast
traffic storms from engulfing the network. Untagged (port-based) and
tagged Virtual Local Area Networks (VLANs), plus support for automatic
Generic VLAN Registration Protocol (GVRP), provide traffic security
and efficient use of network bandwidth. CoS priority queueing ensures
the minimum delay for moving real-time multimedia data across the
network. Some of the management features are briefly described in the
following sections. For further information see,

Authentication

The switch authenticates management access through a Web browser.
User names and passwords can be configured locally or can be verified
through a remote authentication server (the Remote Authentication Dial-In
User Server [RADIUS]). Port-based authentication is also supported through
the IEEE 802.1X protocol. This protocol uses the Extensible Authentication
Protocol over LANs (EAPOL) to request user credentials from the 802.1X
client, and then uses the Extensible Authentication Protocol (EAP) between
the switch and the authentication server to verify the client's right to access
the network through an authentication server (that is, the RADIUS server).
Other authentication options include Simple Network Management Protocol
(SNMP) Version 3, IP address filtering for SNMP/Web-based user interface
management access, and MAC address filtering for port access.
