Hei tātari i te rere o te whatunga, me tuku te mōkihi whatunga ki te NTOP/NPROBE, ki ngā Utauta Haumarutanga me te Aroturuki Whatunga o Waho-o-te-rohe rānei. E rua ngā otinga mō tēnei raruraru:
Whakaata Tauranga(e mōhiotia ana ko SPAN)
Pāwhiri Whatunga(e mōhiotia ana ko te Replication Tap, te Aggregation Tap, te Active Tap, te Copper Tap, te Ethernet Tap, me ētahi atu)
I mua i te whakamārama i ngā rerekētanga i waenga i ngā otinga e rua (Port Mirror me Network Tap), he mea nui kia mārama ki te mahi a te Ethernet. I te 100Mbit me runga ake, ka kōrero ngā kaihautū i roto i te duplex katoa, arā, ka taea e te kaihautū kotahi te tuku (Tx) me te whiwhi (Rx) i te wā kotahi. Ko te tikanga tēnei, i runga i te taura 100 Mbit e hono ana ki te kaihautū kotahi, ko te tapeke o te waka whatunga ka taea e te kaihautū kotahi te tuku/whiwhi (Tx/Rx)) he 2 × 100 Mbit = 200 Mbit.
He tāruarua pākete hohe te whakaata tauranga, arā, ko te pūrere whatunga te kawenga ā-tinana mō te tārua i te pākete ki te tauranga whakaata.
Ko te tikanga o tēnei me mahi te taputapu i tēnei mahi mā te whakamahi i tētahi rauemi (pēnei i te CPU), ā, ka tāruatia ngā aronga e rua ki te tauranga kotahi. E ai ki te kōrero i mua ake nei, i roto i te hononga takirua katoa, ko te tikanga o tēnei
A -> B me B -> A
Kāore te tapeke o A e neke ake i te tere whatunga i mua i te ngaronga o te mōkihi. Nā te mea kāore he wāhi ā-tinana hei tārua i ngā mōkihi. He tikanga pai te whakaata tauranga nā te mea ka taea e te maha o ngā pana (engari ehara i te katoa), nā te mea ko te nuinga o ngā pana he ngoikoretanga o te ngaronga mōkihi, ki te aroturukihia e koe he hononga me te kawenga neke atu i te 50%, ki te whakaata rānei i ngā tauranga ki tētahi tauranga tere ake (hei tauira, whakaata i ngā tauranga 100 Mbit ki tētahi tauranga 1 Gbit). Kāore e kore ko te whakaata mōkihi me whakawhiti rauemi pana, ka utaina pea te taputapu ka heke te mahi whakawhiti. Kia mahara ka taea e koe te hono i te tauranga kotahi ki te tauranga kotahi, i te tauranga kotahi rānei ki te tauranga kotahi, engari i te nuinga o te wā kāore e taea te tārua i ngā tauranga maha ki te 1. (Nō reira, i te mea kei te ngaro te whakaata mōkihi).
He TAP Whatunga (Pūwāhi Uru Whakamutunga)He taputapu pūmārō tino korekore te TAP, ka taea te hopu i ngā waka i runga i te whatunga. He mea whakamahi noa hei aroturuki i ngā waka i waenga i ngā pūwāhi e rua o te whatunga. Mena he taura tūturu te whatunga i waenga i ēnei pūwāhi e rua, ko te TAP whatunga pea te huarahi pai ki te hopu i ngā waka.
E toru ngā tauranga o te whatunga TAP: he tauranga A, he tauranga B, me te tauranga aroturuki. Hei whakatakoto i tētahi tap i waenganui i ngā pūwāhi A me B, ka whakakapia te taura whatunga i waenganui i te pūwāhi A me te pūwāhi B ki ētahi taura e rua, ko tētahi e haere ana ki te tauranga A o te TAP, ko tētahi e haere ana ki te tauranga B o te TAP. Ka tukuna e te TAP ngā waka katoa i waenganui i ngā pūwāhi whatunga e rua, kia hono tonu ai rāua tetahi ki tetahi. Ka tāruatia hoki e te TAP ngā waka ki tana tauranga aroturuki, ā, ka taea ai e te taputapu tātari te whakarongo.
E whakamahia whānuitia ana ngā TAP whatunga e ngā taputapu aroturuki me te kohikohi pēnei i te APS. Ka taea hoki te whakamahi i ngā TAP i roto i ngā tono haumarutanga nā te mea kāore e ārai i te hunga e kite ana i ngā raraunga, kāore e kitea i runga i te whatunga, ka taea te mahi me ngā whatunga takirua-katoa me ngā whatunga kāore i te tiritahitia, ā, ka haere tonu i roto i te ao ahakoa ka mutu te mahi a te taputapu, ka ngaro rānei te hiko.
Nā te mea kāore ngā tauranga Network Taps e whiwhi engari e tuku noa, kāore te pana e mōhio ko wai kei muri i ngā tauranga. Ko te mutunga iho, ka whakapāhohia e ia ngā mōkihi ki ngā tauranga katoa. Nō reira, ki te hono koe i tō pūrere aroturuki ki te pana, ka whiwhi taua pūrere i ngā mōkihi katoa. Kia mahara ka mahi tēnei tikanga mēnā kāore te pūrere aroturuki e tuku i tētahi mōkihi ki te pana; ki te kore, ka whakaaro te pana ehara ngā mōkihi kua patohia mō taua pūrere. Hei whakatutuki i tēnā, ka taea e koe te whakamahi i tētahi taura whatunga kāore anō kia honoa e koe ngā waea TX, ka taea rānei e koe te whakamahi i tētahi atanga whatunga kore-IP (me te kore-DHCP) kāore e tuku mōkihi. Hei whakamutunga, kia mahara mēnā kei te hiahia koe ki te whakamahi i tētahi pato kia kore ai e ngaro ngā mōkihi, kaua e hanumi ngā ahunga, whakamahia rānei he pana kei reira ngā ahunga kua patohia he puhoi ake (hei tauira, 100 Mbit) i te tauranga hanumi (hei tauira, 1 Gbit).
Nā, me pēhea te hopu i te haere o te whatunga? Ngā taputapu whatunga me ngā pūaha whakawhiti whakaata
