Appendix B, Device Specifications & Features

F e a t u r e	D e s c r i p t i o n
Power over Ethernet	Power over Ethernet (PoE) provide power to devices over exist-
	ing LAN cabling, without updating or modifying the network infra-
	structure. Power over Ethernet removes the necessity of placing
	network devices next to power sources. Power over Ethernet can
	be used in the following applications:
	•	IP Phones
	•	Wireless Access Points
	•	IP Gateways
	•	PDAs
	• Audio and video remote monitoring
Private VLANs	Private VLAN ports are a Layer 2 security feature which provide
	isolation between ports within the same Broadcast domain.
RADIUS Clients	RADIUS is a client/server-based protocol. A RADIUS server
	maintains a user database, which contains per-user authentica-
	tion 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 pro-
	vides 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 incom-
	ing 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.
	For more information on SNMP Alarms and Traps, see “SNMP
	Security Global Parameters Page."
SNMP Versions 1, 2 and 3	Simple Network Management Protocol (SNMP) over the UDP/IP
	protocol controls access to the system, a list of community entries
	is defined, each of which consists of a community string and its
	access privileges. There are 3 levels of SNMP security read-only,
	read-write and super. Only a super user can access the commu-
	nity table.
