F e a t u r e	D e s c r i p t i o n
Domain Name System	Domain Name System (DNS) converts user-defined domain
	names into IP addresses. Each time a domain name is assigned
	the DNS service translates the name into a numeric IP address.
	For example, www.ipexample.com is translated to 192.87.56.2.
	DNS servers maintain domain name databases and their corre-
	sponding IP addresses.
Fast Link	STP can take up to 30-60 seconds to converge. During this time,
	STP detects possible loops, allowing time for status changes to
	propagate and for relevant devices to respond. 30-60 seconds is
	considered too long of a response time for many applications.
	The Fast Link option bypasses this delay, and can be used in net-
	work topologies where forwarding loops do not occur.
Full 802.1Q VLAN Tagging Compliance	IEEE 802.1Q defines an architecture for virtual bridged LANs, the
	services provided in VLANs and the protocols and algorithms
	involved in the provision of these services. An important require-
	ment included in this standard is the ability to mark frames with a
	desired Class of Service (CoS) tag value.
GVRP Support	GARP VLAN Registration Protocol (GVRP) provides IEEE
	802.1Q-compliant VLAN pruning and dynamic VLAN creation on
	802.1Q trunk ports. When GVRP is enabled, the device registers
	and propagates VLAN membership on all ports that are part of
	the active underlying Spanning Tree Protocol Features topology.
IGMP Snooping	IGMP Snooping examines IGMP frame contents, when they are
	forwarded by the device from work stations to an upstream Multi-
	cast router. From the frame, the device identifies work stations
	configured for Multicast sessions, and which Multicast routers are
	sending Multicast frames.
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 capabil-
	ity achievable between a given pair of systems. LACP automati-
	cally determines, configures, binds and monitors the port binding
	within the system.
Link Aggregated Groups	Link Aggregated Group (LAG). The system provides up-to eight
	Aggregated Links may be defined, each with up to eight member
	ports, to form a single. 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.
