Better than Span Ports
In.the.past,.Span.ports.were.occasionally.used.to.aggregate.tapped.traffic ..
However,.in.addition.to.missing.Layer.1.and.Layer.2.errors,.Span.ports.
support.very.limited.buffering.and.can.simply.drop.data.during.bursts ..The.
generous.buffers.of.the.10/100/1000.Port.Aggregator.prevents.data.loss.in.
these.conditions .
Security and Visibility
Without.an.IP.address,.monitoring.devices.are.isolated.from.the.network,.
dramatically.reducing.their.exposure.to.attacks ..However,.the.monitoring.
device.connected.to.the.Tap.still.sees.all.full-duplex.traffic.as.if.it.were.in-line,.
including.Layer.1.and.Layer.2.errors ..
Simply Plug It In
Full-duplex.monitoring.is.a.snap.when.each.side.of.the.signal.is.sent.to.the.
same.NIC.on.the.monitoring.device ..All.network.and.monitoring.cables.
required.for.plug-and-play.deployment.are.included.with.the.10/100/1000.
Copper.Port.Aggregator .
Link Fault Detect TM
The.10/100/1000.Copper.Port.Aggregator.features.Link.Fault.Detect.on.
the.Network.ports ..The.Tap.negotiates.separately.with.each.side.of.the.
full-duplex.link,.detecting.if.either.side.fails ..In.the.event.of.a.failure,.the.Tap.
ceases.negotiation.with.the.remaining.side,.enabling.a.clean.fail-over.to.a.
redundant.network.connection.(if.one.is.available) ..Link.Fault.Detect.requires.
that.both.sides.of.the.full-duplex.link.are.communicating.at.the.same.speed .
Reliability
For.extra.uptime.protection,.Net.Optics.Taps.offer.redundant.power.connections ..
Should.the.primary.power.source.fail,.the.Tap.automatically.switches.to.the.
backup.power.source ..Power.LEDs.on.the.front.of.the.Tap.indicate.the.current.
power.source.–.even.if.power.is.lost.and.reapplied,.the.network.is.not.affected .
