Table 9 Features of the Baseline Switch 2924-PWR Plus (continued)

Feature	Description
Power over Ethernet	Provides power to devices over LAN connection.
RADIUS Clients	RADIUS is a client/server-based protocol. A RADIUS server maintains a
	user database, which contains per-user authentication information, such
	as user name, password and accounting information.
Rapid Spanning Tree	Spanning Tree can take 30-60 seconds for each host to decide whether its
	ports are actively forwarding traffic. Rapid Spanning Tree (RSTP) detects
	uses of network topologies to enable faster convergence, without
	creating forwarding loops.
Remote Monitoring	Remote Monitoring (RMON) is an extension to SNMP, which provides
	comprehensive network traffic monitoring capabilities (as opposed to
	SNMP which allows network device management and monitoring).
	RMON is a standard MIB that defines current and historical MAC-layer
	statistics and control objects, allowing real-time information to be
	captured across the entire network.
Self-Learning MAC Addresses	The device enables automatic MAC address learning from incoming
	packets. The MAC addresses are stored in the Bridging Table
SNMP Alarms and Trap Logs	The system logs events with severity codes and timestamps. Events are
	sent as SNMP traps to a Trap Recipient List.
SNMP Versions 1 and 2	Simple Network Management Protocol (SNMP) over the UDP/IP protocol
	controls access to the system.
Spanning Tree Protocol	802.1d Spanning tree is a standard Layer 2 switch requirement that
	allows bridges to automatically prevent and resolve L2 forwarding loops.
	Switches exchange configuration messages using specifically formatted
	frames and selectively enable and disable forwarding on ports.
SSL	Secure Socket Layer (SSL) is an application-level protocol that enables
	secure transactions of data through privacy, authentication, and data
	integrity. It relies upon certificates and public and private keys.
Static MAC Entries	MAC entries can be manually entered in the Bridging Table, as an
	alternative to learning them from incoming frames. These user-defined
	entries are not subject to aging, and are preserved across resets and
	reboots.
TCP	Transport Control Protocol (TCP). TCP connections are defined between 2
	ports by an initial synchronization exchange. TCP ports are identified by
	an IP address and a 16-bit port number. Octets streams are divided into
	TCP packets, each carrying a sequence number.
TFTP Trivial File Transfer Protocol	The device supports boot image, software and configuration
	upload/download via TFTP.
Virtual Cable Testing	VCT detects and reports copper link cabling occurrences, such as open
	cables and cable shorts.
