    Typically,.full-duplex.monitoring.with.a.network.tap.requires.two.NICs.(or. a.dual.channel.NIC).–.one.interface.for.each.side.of.the.tapped.full-duplex. connection ..The.Dual.Port.Aggregator.Tap.combines.and.regenerates.these. streams,.sending.all.aggregated.data.out.two.separate.passive.monitoring. ports ..The.best.part.of.this.innovation.is.the.onboard.memory.to.make.sure. traffic isn’t dropped during bursts. Response Ready When active responses to network events are required, the first monitoring port.can.be.changed.to.an.Active.Response.Port.using.a.hardware.switch ..The. Active.Response.Port.buffers.and.transmits.into.the.network.link.any.type. of.Ethernet.packet,.from.a.simple.TCP.reset.to.ICMP.messages ..The.Active. Response.Port.can.be.easily.switched.back.to.passive.monitoring.via.the. hardware.switch .. The.combination.of.active.response.capability.and.passive.monitoring.in. the.Tap.reduces.the.number.of.devices.and.network.ports.required.for.active. response.functionality . Buffering Prevents Lost Data The.Dual.Port.Aggregator.Tap.with.Active.Response.is.designed.to.handle.the.

An operating system.and.NICs.that.enable.binding.are.often.required.to.achieve.the.same. functionality.as.the.Dual.Port.Aggregator.Tap ..In.contrast,.the.Dual.Port. Aggregator Tap requires no additional components or configuration on the monitoring.devices ..

    10/100 Port Aggregator Tap Active Response Tap FAQs Q: What types of active responses are supported? A:.With.an.Active.Response.Dual.Port.Aggregator.Tap,.an.administrator.can. transmit.any.type.of.Ethernet.packet.back.into.the.original.link,.supporting.all. common.types.of.active.responses.generated.by.intrusion.detection.systems,. and.by.intrusion.prevention.systems.deployed.in.passive.mode ..The.most. common response types are TCP resets, and firewall rule changes. While the Tap.can.support.both.types.of.responses,.we.advocate.extreme.caution.in.dy- namically updating firewall rules due to the risk of disabling network services. Because most firewalls are managed out-of-band, however, it is unlikely that the.Regeneration.Tap.will.be.part.of.a.rule.change.scenario ..
