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

Feature	Description
LACP	LACP uses peer exchanges across links to determine, on an ongoing basis,
	the aggregation capability of various links, and continuously provides the
	maximum level of aggregation capability achievable between a given pair
	of systems. LACP automatically determines, configures, binds and
	monitors the port binding within the system.
Link Aggregated Groups	The system provides up to eight Link Aggregated Groups (LAGs).
	Aggregated Links may be defined, each with up to eight member ports,
	to form a single LAG. LAGs provide:
	■ Fault tolerance protection from physical link disruption
	■	Higher bandwidth connections
	■	Improved bandwidth granularity
	■ High bandwidth server connectivity
	■ LAG is composed of ports with the same speed, set to full-duplex
		operation.
MAC Address Capacity Support	The device supports up to 8K MAC addresses. The device reserves specific
	MAC addresses for system use.
MAC Multicast Support	Multicast service is a limited broadcast service, which allows one-to-many
	and many-to-many connections for information distribution. Layer 2
	Multicast service is where a single frame is addressed to a specific
	Multicast address, from where copies of the frame are transmitted to the
	relevant ports.
MDI/MDIX Support	The device automatically detects whether the cable connected to an RJ-45
	port is crossed or straight through, when auto-negotiation is enabled.
	Standard wiring for end stations is Media-Dependent Interface (MDI) and
	the standard wiring for hubs and switches is known as Media-Dependent
	Interface with Crossover (MDIX).
Password Management	Password management provides increased network security and improved
	password control. Passwords for HTTP, HTTPS, and SNMP access are
	assigned security features. For more information on Password
	Management, see “Default Users and Passwords” page 29.
Port-based Authentication	Port-based authentication enables authenticating system users on a
	per-port basis via an external server. Only authenticated and approved
	system users can transmit and receive data. Ports are authenticated via
	the Remote Authentication Dial In User Service (RADIUS) server using the
	Extensible Authentication Protocol (EAP).
Port-based Virtual LANs	Port-based VLANs classify incoming packets to VLANs based on their
	ingress port.
Port Mirroring	Port mirroring monitors and mirrors network traffic by forwarding copies
	of incoming and outgoing packets from a monitored port to a monitoring
	port. Users specify which target port receives copies of all traffic passing
	through a specified source port.
