Switch Fabric and
OpenWare Protocol Features
•SupportsbothLayer2(L2)andLayer3
(L3)packetswitching.Packetsare
categorizedbytheMACaddressesfor
L2 switching and by IP addresses for
L3 switching.
•QoSprioritization(IEEE802.1P)permits
classifying packet priorities which is ben-
eficial in delay-sensitive applications.
•Packetfilteringtopreventforwardingof
certain packets; filtering capabilities are
availableinLayers2-7.
•Linkaggregation(IEEE802.3ad)linksa
group of physical ports creating a single
logical port to provide higher bandwidth
and increase redundancy between
switches. The fabric is capable of full wire
speedswitching,allowingamaximum
aggregate throughput that is the sum of
all aggregated ports.
• VirtualLANs(VLANs)(IEEE802.1Q)defines
aforwarding(switching)domain;supports
upto4096VLANs.
• MultipleSpanningTreeProtocol(MSTP)
(IEEE802.1D-2004)enablesautomaticand
rapid determination of an optimal loop-
free topology from an arbitrary network
of enabled switches with duplicate and
redundant connections; supports rapid
reconfiguration in the event of a link or
switch failure; backward compatible with
RSTP and STP.
•Broadcaststormcontrolscreensexcessive
traffic and controls the rate limit for each
port and prevents flooding in the network.
•IGMPsnoopingpermitstheswitchtomoni-
tor IGMP interactions between hosts and
routers and to adjust its forwarding tables
accordingly resulting in more efficient
bandwidth use.
•Portmirroringeasesdebugandpacket
pattern study. This is a method to observe
on one port traffic that is flowing on
another port.
•High-availabilityHotSwapthatcomplies
with PICMG 2.1 Rev 2; the switch may be
removed and replaced while the system
is operational.
L-3 IP Routing Protocols
•OSPF(OpenShortestPathFirst),aflexible
link state protocol, tests the state of links
and transmits that information through-
out the system to establish the short-
est path to the destination. This protocol
also load balances by distributing traffic
equally among routes. Messages may also
be routed based on the type of service so
that critical messages can transverse the
most reliable routes.
•RIP(RoutingInformationProtocol),aneasy-
to implement, dynamic routing protocol,
allowsrouterstoexchangeinformationfor
computing routes through networks. Rout-
ing tables are used to store destination
and metric pairs.
• VRRP(VirtualRouterRedundancyProtocol)
eliminates single points of failure on a net-
work. Using an election protocol to provide
failover for forwarding packets, VRRP pro-
vides a higher availability default path.
OpenWare Switch Management
Environment
OpenWareisavailableexclusivelyonselected
NETernity fully managed Layer 2/3 Ethernet
switches. Comprehensive and powerful, this
switch management environment provides
integrated management services including
configuration, monitoring, switching control,
addressing, routing and all supported proto-
cols. Configuration and monitoring functions
are accessible from a serial console or via a
network. Supported access methods include
Telnet,SSHandSNMP.

results from the wide range of protocols
supported. These protocols are defined
by RFCs, and cover a range of operations:
Switching,VLANs,Aggregation,Multicast,
Filtering,Routing,QoS,andManagement.
NETernity switches with OpenWare offer
broad functionality and support com-
munications within the chassis as well as
supporting the network outside of
the chassis.
•MSTP,thelatestversionoftheSpanning
