handles the routing functions for data moving from one open system to
another.
Link Aggregation Defines a network link aggregation method which specifies how to create a
single high-speed logical link that combines several lower-speed physical links.
Link Aggregation
Control Protocol
(LACP) Allows ports to automatically negotiate an aggregated link with LACP-
configured ports on another device.
Media Access Control

Port Mirroring A method whereby data on a target port is mirrored to a monitor port for
troubleshooting with a logic analyzer or RMON probe. This allows data on the
target port to be studied unobstructively.
Remote Monitoring
(RMON) 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.
Remote Authentication
Dial-in User Service
(RADIUS) An authentication protocol that uses a central server to control access to
RADIUS-compliant devices on the network. A RADIUS server can be
programmed with a database of multiple user name/password pairs and
associated privilege levels for each user or group that requires management
access to this switch.
RJ-45 Connector A connector for twisted-pair wiring.
