I-"Extreme Extended Edge" (eyaziwa nangokuthi i-Virtual Port Extender - VPEX) ubuchwepheshe obusha obuye bethulwa okokuqala ohlelweni lokusebenza lwe-EXOS ngokukhululwa kwe-22.5. Isixazululo ngokwaso sisekelwe ezingeni le-IEEE 802.1BR (Bridge Port Extension), futhi njengengxenye yokukhishwa kwe-EXOS 22.5, usekelo lolayini wehadiwe we-ExtremeSwitching V400 wengeziwe.
I-"VPEX Bridge" iyiswishi ebonakalayo ehlanganisa izingxenye ezifana ne - Controlling Bridge (CB) kanye neBridge Port Extender (BPE). Ukuqinisekisa ukubekezelelana kwamaphutha, kungenzeka ukuxhuma kuma-CB amabili ngaphakathi kweswishi eyodwa ebonakalayo usebenzisa ubuchwepheshe be-MLAG. Idizayini yeswishi enjalo ebonakalayo ifana ngokuqondile nokushintsha kwe-chassis yakudala noma inqwaba yamaswishi. Futhi uma kunengqondo ye "Control Plane" lokhu kuyiqiniso noma ngaphansi, khona-ke umsebenzi we "Data Plane" uhluka kakhulu. Phela, inhloso ye-802.1br ukuxhuma imbobo ekude nesevisi yendawo ye-MAC (Media Access Control), kuyilapho uhlukanisa ithrafikhi yamachweba akude.
Ibhuloho elilawulayo
- Iphuzu lokulawula elilodwa kuphela
- Konke ukucushwa kwenzeka endaweni ku-CB
- Ukwesekwa kwe-VPEX kufanele kucushwe, ukuqalisa kabusha kuyadingeka ukuze ushintshe imodi yokusebenza
- CB njalo slot #1
- Ekukhishweni kwamanje, i-CB isekela ukuxhuma kanyekanye kufika ku-48 BPE
- Imodi ye-CB isekelwa kwezinye izinkundla zehadiwe (okwamanje i-X670G2 ne-X690, ezinye izinkundla zizongezwa uma sezitholakala)
- Amalayisense e-EXOS asebenza ku-CB kuphela
- I-VPEX ayidingi amalayisense engeziwe
- Ibophezelekile ngokugcwele ekucutshungulweni kwedatha yendiza nokuhlunga kwethrafikhi
- Iqukethe ukumelwa okubonakalayo kwembobo ngayinye "enwetshiwe".
Ibhuloho Port Extender
- Amadivayisi e-BPE aphethwe njengezikhala zokushintshwa kwe-chassis
- Izikhala ze-BPE zibalwa ukusuka ku-100 kuye ku-162

- Ama-BPE awakwenzi ukushintsha kwendawo. Ngenxa yalokho, yonke ithrafikhi ihunyushwa ku-CB futhi, uma kunesidingo, idluliselwe echwebeni elingumakhelwane le-slot ye-BPE efanayo, ibuyiselwe emuva. (I-BPE ithola iphakethe yengeza unhlokweni we-E-TAG futhi iyithumele echwebeni elikhuphuka nomfula)
Ukuze usebenze njenge-BPE, kwethulwa inkundla yehadiwe ye-ExtremeSwitching V400 entsha. Ihlanganisa izinwebe zembobo zamachweba angu-24/48 10/100/1000 e-Base-T anosekelo lwe-PoE noma ngaphandle kwawo. Amamodeli angama-24 anezimbobo ezimbili ze-10G, amamodeli angama-48 anezimbobo ezine ze-10G.
umsebenzi Izici
Ama-Topology ane-CB eyodwa noma amabili kanye nama-BPE angama-cascade amane ayasekelwa. Izimbobo ze-Cascaded zingahlanganiswa zibe i-LAG (kufika kumachweba angu-4 amamodeli we-V400-48t/p). Iziteshi zokuphela zingaxhuma ezindaweni ezahlukene ze-BPE zisebenzisa i-LAG.
Ukutholwa nokusebenza kwe-BPE kusekelwe kuzivumelwano ezifana nalezi:
- I-LLDP - ukutholwa kokuqala kanye nokunqunywa kohlobo namandla edivayisi exhunyiwe
- I-ECP - "Edge Control Protocol" ezokuthutha ze-PE-CSP
- I-PE-CSP - "I-Port Extender Control and Status Protocol" ilungiselela ukulawula kwe-BPE nge-Controlling Bridge
- I-LACP - ukusetha i-LAG phakathi kwezimbobo ze-"cascade" <β> "ezikhuphukayo".
Uma i-failover design enama-CB amabili kanye ne-MLAG isetshenziswa, lapho-ke i-CB eyodwa iqaliswa kabusha, ama-BPE azoqhubeka nokuthumela ithrafikhi ngeBhuloho Elilawulayo elisele. Uma okuwukuphela kwe-CB iqaliswa kabusha, i-BPE izovimbela ngokomthetho izimbobo zayo "ezandisiwe".
Ukuze kube lula ukulungisa i-topology nge-2 CBs, ikhono lokumisa izimbobo ze-MLAG zabo bobabili ontanga kusuka kunoma imaphi ama-CBs lengeziwe. Imodi ibizwa ngokuthi "i-orchestration ye-mlag", kuyilapho ontanga bevumelanisa ingxenye yokucushwa ehlobene nezilungiselelo zembobo ye-MLAG. Ukusetha kufana nokusetha "ama-virtual-routers" ngokwezifiso.

Umsebenzi we-"Controling Bridge" uyatholakala ngemva kokufaka imojuli yamahhala ye-EXOS, enesandiso se-.xmod. Le mojula efanayo izobamba izithombe ezibuyekeziwe ze-BPE. Empeleni, lapho i-CB ne-BPE zitholana, i-CB ihlola inguqulo ye-firmware efakwe ku-BPE futhi, uma kunesidingo, iyibuyekeze ngokuzenzakalelayo.
Izici ezingenhla zokusebenza zikwenza kube lula futhi kusheshe ngangokunokwenzeka ukufaka indawo ye-BPE uma kunesidingo. Njengoba izikhala ze-BPE zingagcini ukulungiselelwa futhi aziboshiwe nganoma iyiphi indlela ohlelweni, ngokushesha ngemva kokuba idivayisi ishintshiwe futhi amandla avuliwe, i-BPE izobona i-CB futhi isebenzise ukucushwa okukhona, futhi uma i-firmware idinga. ezobuyekezwa.
Lesi sixazululo sifaneleka kahle kumanethiwekhi anezikhombisi-ndlela ezihamba phambili zethrafikhi eNyakatho/eNingizimu, njengamanethiwekhi ekhampasi, amanethiwekhi amabhizinisi kwezokuthutha, ezemfundo, ezikhungweni zebhizinisi, nokunye. Futhi siyaphinda futhi ukuthi izinzuzo zamanethiwekhi akhelwe kusixazululo se-Extreme Extended Edge kuzoba:
- Ukunciphisa inani lezendlalelo zesakhiwo senethiwekhi evamile ngokuya ngokucushwa nokuphatha
- Ukukala kalula nokusetshenziswa
- Asikho isidingo sokuba nekhonsoli ezinikele noma ukuxhumana kwe-OOB Mgmt kuzikhala ze-BPE
- Ukwehliswa kwelayisensi (uma kunesidingo, sebenza kuphela ku-NE)
- Iphuzu elilodwa lokucushwa, ukuqapha kanye nokuxazulula inkinga
- Khombisa ku-NMS njengeswishi eyodwa
- Asikho isidingo sokuqeqeshwa okwengeziwe kanye nokwandiswa kwabasebenzi
