* ieee 802.1x network access control offers standards-based security combined with radius authentication * radius authenticated device access (rada) provides authentication of attached devices via mac address for an additional level of endpoint security * access control lists (acls) enable usage policies at each point of access to the network via the switch. * integrated stack management with single ip management of up to sixteen units. * bandwidth rate limiting and protocol filtering enforces controls on each port for efficient use of network resources and prioritization of delay sensitive voip traffic. * "dual-personality" gigabit ethernet, with choice of copper or fiber media for flexible uplinks. * multicast filtering and rapid spanning tree protocol improve qos, scalability and network availability. * layer 3 static routing gives additional flexibility in deployment to boost network performance. * secure management with authentication and encryption of management traffic via secure shell (ssh v2) and snmp v3.
