"Eeg Extended Extreme", ama beddelashada ku salaysan IEEE 802.1BR

Extreme Extended Edge (sidoo kale loo yaqaan Virtual Port Extender - VPEX) waa tignoolajiyad cusub oo markii ugu horeysay lagu soo bandhigay nidaamka hawlgalka EXOS iyadoo la sii daayay 22.5. Xalka laftiisa wuxuu ku saleysan yahay heerka IEEE 802.1BR (Bridge Port Extension), iyo iyadoo qayb ka ah sii deynta EXOS 22.5, taageerada khadka cusub ee ExtremeSwitching V400 ayaa lagu daray

"VPEX Bridge" waa bedel toos ah oo ka kooban qaybo ay ka mid yihiin Controlling Bridge (CB) iyo Bridge Port Extender (BPE). Si loo hubiyo dulqaadka cilada, waxa suurtagal ah in lagu xidho laba CB-yada gudaha hal beddelka dalwaddii iyadoo la isticmaalayo tignoolajiyada MLAG. Naqshadeynta beddelka farsamada casriga ah ee noocan oo kale ah ayaa dib u xasuusinaysa beddelka chassis-ka caadiga ah ama xidhmooyin shido ah. Oo haddii macquulka ah ee shaqada "Control Plane" tani waa wax badan ama ka yar run, ka dibna shaqada "Diyaaradda Data" aad u kala duwan. Ka dib oo dhan, ujeedada 802.1br waa in lagu xiro deked fog iyo adeegga MAC (Media Access Control) ee maxaliga ah, iyada oo la go'doominayo taraafikada dekedaha fog.

Xakamaynta Buundada

• Hal iyo barta kantaroolka kaliya
• Dhammaan qaabaynta waxay ka dhacdaa gudaha CB
• Taageerada VPEX waa in la hawlgeliyaa, reboot ayaa loo baahan yahay si loo beddelo qaabka hawlgalka
• CB had iyo jeer waa booska #1
• Siideynta hadda, CB waxay taageertaa isku xirka isku mar ee ilaa 48 BPE
• Habka CB waxaa lagu taageeraa qalabyada qalabka qaarkood (hadda X670G2 iyo X690, goobo kale ayaa lagu dari doonaa marka la sii daayo)
• Shatiyada EXOS waxay khuseeyaan oo keliya SV
• VPEX uma baahna shatiyo dheeraad ah
• Si buuxda uga masuula habaynta xogta-diyaarada iyo shaandhaynta taraafikada
• Waxay ka kooban tahay matelaad dalwaddiinta ah ee deked kasta oo "la fidsan".

Buundada Dekadda Extender

• Qalabka BPE waxaa loo maamulaa sidii boosaska beddelka chassis
• boosaska BPE waxa lagu tiriyaa 100 ilaa 162

• BPE-yadu ma sameeyaan beddelka deegaanka. Natiijadu waxay tahay, dhammaan taraafikada waxaa loo maro CB oo, haddii loo baahdo, loo gudbiyo deked ku dhow isla booska BPE, dib ayaa loo soo celiyay. (BPE waxay helaysaa baakidhka, waxay ku daraysaa madaxa E-TAG waxayna u dirtaa dekedda sare)

Si loogu shaqeeyo sidii BPE, qalab cusub oo qalabeed, ExtremeSwitching V400, ayaa la soo bandhigay. Waxa ku jira balaadhinta dekedaha 24/48 10/100/1000 dekedaha Saldhig-T oo leh ama aan lahayn taageerada PoE. Moodooyinka leh 24 dekedood waxay leeyihiin laba dekedood oo 10G ah, halka moodooyinka leh 48 dekedood ay leeyihiin afar dekedood oo 10G ah.

Features shaqada

Topologies leh hal ama laba CBs iyo ilaa afar silsilado VPE ah oo cascad ah ayaa la taageerayaa. Dekadaha cascadable waxaa lagu dari karaa LAG (ilaa 4 dekedood oo loogu talagalay moodooyinka V400-48t/p). Saldhigyada dhamaadka waxay ku xidhi karaan boosaska BPE ee kala duwan iyagoo isticmaalaya LAG.

Ogaanshaha BPE iyo hawlgalku waxay ku salaysan yihiin borotokoollada sida:

• LLDP - ogaanshaha bilowga ah iyo go'aaminta nooca iyo awoodaha qalabka ku xiran
• ECP - "Bartakoolka Kontoroolka Edge" gaadiidka PE-CSP
• PE-CSP - "Kontoroolka Fidiyaha Dekadda iyo Hab-maamuuska Xaaladda" oo ku habeynaya kantaroolka BPE ee Kontaroolka Buundada
• LACP - dejinta LAG inta u dhaxaysa "cascade" <-> "kor u kaca" dekedaha

Haddii naqshad u dulqaadanaysa cilladaha oo leh laba CB iyo MLAG la isticmaalo, markaa marka hal CB dib loo bilaabo, BPE waxay sii wadi doontaa inay u dirto taraafikada Buundada Kontroolka ee hadhay. Haddii CB kaliya uu dib u bilaabo, markaa BPE waxay maamul ahaan baabi'in doontaa dekedaheeda "la fidiyey".
Si ay ugu habboonaato habaynta topology-ga leh 2 CBs, awoodda lagu habeeyo dekedaha MLAG ee labada faca mid ka mid ah CB-yada ayaa lagu daray. Habka waxaa loo yaqaan "mlag orchestration", kaas oo asxaabtu ay isku daraan qaybta qaabeynta ee la xiriirta dejinta dekedaha MLAG. Habayntu waxay la mid tahay dejinta hab-dhaqanka “virtual-router”.

Shaqada "Controlling Bridge" waa la heli karaa ka dib marka la rakibo moduleka bilaashka ah ee EXOS, kaas oo leh kordhinta .xmod. Qaybtan la midka ah waxay ka kooban tahay sawirro cusub oo loogu talagalay BPE. Dhab ahaantii, marka CB iyo BPE ay is ogaadaan, CB waxay hubisaa nooca firmware-ka ee lagu rakibay BPE iyo, haddii loo baahdo, si toos ah u cusbooneysiiya.

Tilmaamaha hawlgalka ee kor ku xusan waxay suurtogal ka dhigayaan in booska BPE lagu beddelo si fudud oo degdeg ah sida ugu macquulsan haddii loo baahdo. Maaddaama boosaska BPE aysan keydin qaabeynta oo aysan ku xirneyn sinaba nidaamka, isla markiiba ka dib markii la beddelo aaladda oo la shido awoodda, BPE waxaa ogaan doona SV oo qaabeynta hadda jirta ayaa lagu dabaqi doonaa, sidoo kale haddii firmware-ka waa la cusbooneysiiyay.

Xalkani wuxuu si fiican ugu habboon yahay shabakadaha leh jihada taraafikada ee Waqooyiga/Koonfurta, sida shabakadaha kambaska, shabakadaha ganacsiga ee saadka, qaybaha waxbarashada, xarumaha ganacsiga iyo kuwa kale. Oo waxaan mar kale ku celinaynaa in faa'iidooyinka shabakadaha lagu dhisay xalka "Extreme Extended Edge" ay noqon doonaan:

• Yaraynta tirada lakabyada qaab dhismeedka shabakada dhaqameed ee qaabaynta iyo maamulka
• Si fudud loo cabbiro loona hawlgelin karo
• Looma baahna in la yeesho konsole u go'an ama OOB Mgmt isku xirka boosaska BPE
• Shatiga la dhimay (haddii loo baahdo, dalbo oo keliya NE)
• Hal dhibic oo qaabaynta, la socodka iyo cilad-baadhista
• U muuji NMS sidii hal beddel
• Looma baahna tababar dheeraad ah ama balaadhinta shaqaalaha
