Ixesha lokuqonda, iRpan ne-ERSPAN: Iindlela zobuchule zeNethiwekhi zeNethiwekhi

I-Spani, i-RSPAn, kunye ne-ERSPAN ziindlela ezisetyenzisiweyo kwinethiwekhi yokufaka nokubeka iliso kwitrafikhi yohlalutyo. Nalu umbono ngokufutshane:

Spinal (uququzelwe khona)

Injongo: isetyenziselwa ukugcwala kwezithuthi ezivela kwizibuko elithile okanye ii-vhlns kwi-switch ukuya kwenye yezibuko lokujonga.

Sebenzisa ityala: Ilungele uhlalutyo lwasekhaya kwi-switch enye. Izithuthi zibonakaliswa kwizibuko ezichongiweyo apho uhlalutyo lwenethiwekhi lungayifumana.

I-RSPAN (ixesha elikude)

Injongo: Izakhono zexesha leendawo zokutshintsha ezininzi kwinethiwekhi.

Sebenzisa ityala: Ivumela ukubekwa kweliso kwitrafikhi ukusuka kwelinye iswitshi ukuya kwenye ngaphezulu kwekhonkco le-trunk. Iluncedo kwiimeko apho isixhobo sokubeka iliso esikwe kutshintsho olwahlukileyo.

I-ERSPAN (i-spaplated span)

Injongo: Ukudibanisa i-RSPAn kunye neGre (i-Eleeric Ecepsing) ukuhambisa itrafikhi yendlela.

Sebenzisa ityala: Ivumela ukubekwa esweni kwetrafikhi kuyo yonke inethiwekhi. Oku kuluncedo kulwakhiwo oluntsonkothileyo apho kufuneka khona iimoto eziza kuqhotyoshelwa ngaphezulu.

Guqula uhlalutyo lwezibuko (ixesha) yinkqubo esebenzayo, yokusebenza ephezulu yendlela ephezulu. Iyalathisa okanye ibonisa itrafikhi ye-port ye-port okanye i-vlan ukuya kwindawo eya kuyo. Oku ngamanye amaxesha kubizwa njengeliso kwiliso leseshoni. U-Spat usetyenziselwa ukulungisa ingxaki yokunxibelelana nengcaciso kunye nokulwa kwenethiwekhi kunye nokusebenza, phakathi kwabanye abaninzi. Zintathu iintlobo zezithuba ezixhaswayo kwiimveliso ze-cisco ...

a. Ixesha okanye ixesha lendawo.

b. I-Spanity span (i-RSPAn).

c. Isithuba sexesha elikhutshiweyo ekude (Erpan).

Ukwazi: "Ukuncwina kwe-Tect Shecker Plecker Plecker enesithuba se-Span, iRpan kunye ne-ErSPAN"

I-Sparing / Trafick Traing / Tex Sheraring isetyenziselwa iinjongo ezininzi, ngezantsi kubandakanya ezinye.

-Ukumiliselwa kwe-ID / ips kwimodi yokuziphatha.

-I-VIIP Fowunela iZisombululo zokurekhoda.

-Izizathu zokuthotyelwa koKhuseleko zokubeka iliso kunye nokuhlaziya itrafikhi.

-Ingxaki yonxibelelwano, ukubeka iliso kwitrafikhi.

Nokuba loluphi uhlobo lokuqhuba isithuba, umthombo onokuba naluphi na uhlobo lwezibuko, i-port ye-port, i-probs, i-ethen.

Iiseshoni zeSpance ixhasa ukubekwa kweliso kwiTrafiki yeTraffere (I-Inress Stert), ukuqaqamba kwe-Erthy (Order), okanye iTrafting Roths) kwiindlela zombini.

-I-Ingerress ixesha (RX) lezatifikethi ezifunyenwe ngamachweba kunye nee-vhla kwi-port. SPAN copies the traffic before any modification (for example before any VACL or ACL filter, QoS or ingress or egress policing).

-I-ERESS SPIMT (TX) Iikopi ezidluliselwa kwitrafikhi kwi-ports kunye nee-vhls ukuya kwizibuko eliya kulo. Konke ukucoca okanye ukuguqulwa kwemvume okanye isihluzo se-ACL, QOS okanye i-Inress okanye i-Ingress okanye i-ERORORORORORORORORORORORORORORORORORE Izenzo zithatyathwa kwiTrafikhi yeTekisi.

- Xa la magama aphambili asetyenziswayo, qala iikopi zendlela efunyenweyo

I-Span / i-RSPAN ihlala ihoya i-CDP, i-STP BP, VTP, DTP kunye nezakhelo zehecp. Nangona kunjalo ezi ntlobo zendlela zinokuthunyelwa phambili ukuba i-encaption rect iqwalaselwe.

Ixesha okanye ixesha lendawo

Thambisa izibuko zokugcwala ukusuka kwenye okanye ngaphezulu isinxibelelanisi sokutshintshela kwi-switch enye okanye ezingaphezulu kwi-switch efanayo; Yiyo ke loo nto ibizwa ngokuba yi-Spinal Span.

Izikhokelo okanye izithintelo kumnini-ndlu

- Zombini ungqimba ezi-2 ezitshintshileyo kunye nobeko lwamazibuko ama-3 zinokulungiswa njengomthombo okanye iibreyini zendawo.

-Umthombo unokuba lizibuko elinye okanye ngaphezulu okanye i-vlan, kodwa hayi umxube kwezi.

-Izibuko leTrunk ziyizibuko elisemthethweni elixubeneyo ezixubeneyo nezibuko elingelilo i-trunk.

-Ukuzi ukuya kumazibuko angama-64 anokuqwalaselwa kwiswitshi.

- Xa silungiselela izibuko eliya kuyo, ubumbeko lwayo lwantlandlolo lubhalwa ngaphezulu. Ukuba ukucwangciswa kweSpat Spayitywe, isimo sentsusa sezibuko liyabuyiselwa.

- Xa uqwalasela izibuko eliya kuyo, izibuko lisuswa kulo naliphi na ibhulukhwe ye-Ethernkannel ukuba ibiyinxalenye yenye. Ukuba yayilizibuko elibiweyo, ukucwangciswa kwentaba ngaphezulu koqwalaselo lwezibuko oluqhutywa.

-Izibuko elizisiweyo azixhasi ukhuseleko lwezibuko, 802.x ukungqinisisa, okanye i-vlans yabucala.

-Izibuko linokuthatha njengezibuko eliya kwiseshoni enye kuphela.

-Izibuko alinakuqwalaselwa njengezibuko elifikayo ukuba sisibuko leseshoni yesithuba okanye inxenye yoMthombo weVlan.

I-Port Channel Channel Popys (i-Ethernkaschanel) inokulungiswa njengezibuko lemithombo kodwa hayi i-port ye-Style yendawo.

-Ukubaleka kwendlela "zombini" ngokungagqibekanga kwimithombo yeentaba.

- Iindawo ezinamazibuko azithathi nxaxheba kwimeko ye-Spanin. Ayikwazi ukuxhasa i-DTP, i-CDP, njl. Isithuba sendawo siquka i-BPDUR kwi-Itchlower esweni, ke nayiphi na i-BPDUS eboniswe kwizibuko lendawo eliya kuyokwa. Yiyo loo nto ungaze uxhume iswitshi kolu hlobo lwe-sty njengoko inokubangela ilogo yenethiwekhi. Izixhobo ze-AI ziya kuphucula ukusebenza kakuhle emsebenzini, kwayeI-AI engabonakaliyoInkonzo inokuphucula umgangatho wezixhobo ze-AI.

Xa i-vlan iqwalaselwe njengoMthombo (ubukhulu becala wabizwa ngokuba yi-VSPAn) kunye no-Inress kunye neepakethi eziPhezulu kwi-POCKETS kuphela, ukuba iipakethi zitshintshele kwi-vlan enye kuphela. Ikopi enye yepakethi ivela kwitrafikhi ye-ingeress kwi-Ingerress Port, kwaye enye ikopi yepakethi ivela kwi-Erthy Port.

- I-VSPAn ibeka i-vssan ibeka itrafikhi kuphela enamagqabi okanye ingena kwi-2 ports kwi-vlan.
