how to create a single high-speed logical link that combines several
lower-speed physical links.

within the assigned VLAN. Data traffic on downlink ports can only be
forwarded to, and from, uplink ports.

Remote Authentication Dial-in User Service (RADIUS)

RADIUS

is a logon authentication protocol that uses software running on

a central server to control access to RADIUS-compliant devices on the
network.

RMON provides comprehensive network monitoring capabilities. It
eliminates the polling required in standard SNMP, and can set alarms on a
variety of traffic conditions, including specific error types.

RSTP

reduces the convergence time for network topology changes to

about 10% of that required by the older IEEE 802.1D STP standard.

can authenticate users with a cryptographic key, and encrypt data
connections between management clients and the switch.
