Yakanyanya Yakawedzerwa Edge (inozivikanwawo seVirtual Port Extender - VPEX) tekinoroji nyowani yakatanga kuunzwa muEXOS inoshanda sisitimu nekuburitswa 22.5. Mhinduro yacho pachayo yakavakirwa paIEEE 802.1BR (Bridge Port Extension) standard, uye sechikamu chekuburitswa kweEXOS 22.5, rutsigiro rweiyo ExtremeSwitching V400 hardware mutsara yakawedzerwa.
"VPEX Bridge" ishanduko chaiyo ine zvinhu zvakaita seKudzora Bridge (CB) uye Bridge Port Extender (BPE). Kuve nechokwadi chekushivirira kukanganisa, zvinokwanisika kubatana kune maviri CBs mukati meimwe chaiyo switch uchishandisa MLAG tekinoroji. Dhizaini yeiyo chaiyo switch inoyeuchidza yekirasi chassis switch kana stack yema switch. Uye kana mune logic ye "Control Plane" basa iri riri rechokwadi kana zvishoma, saka basa re "Data Plane" rinosiyana zvakanyanya. Mushure mezvose, chinangwa che802.1br ndechekubatanidza chiteshi chiri kure kune yemuno MAC (Media Access Control) sevhisi, uku uchiparadzanisa traffic kubva kumadoko ari kure.
Kudzora Bridge
- Imwe uye chete control point
- Kugadziriswa kwese kunoitika munharaunda paCB
- VPEX tsigiro inofanira kuitwa, reboot inodiwa kuti uchinje maitiro ekushanda
- CB inogara iri slot #1
- Mukuburitswa kwazvino, CB inotsigira kubatanidza panguva imwe chete kusvika ku48 BPE
- CB modhi inotsigirwa pane mamwe mapuratifomu ehardware (ikozvino X670G2 uye X690, mamwe mapuratifomu achawedzerwa sezvaanoburitswa)
- Marezinesi eEXOS anoshanda chete kuSV
- VPEX haidi mamwe marezinesi
- Kunyatsoita basa rekugadzirisa data-ndege uye kusefa kwetraffic
- Iine inomiririra inomiririra yega yega "yakawedzerwa" chiteshi
Bridge Port Extender
- BPE zvishandiso zvinodzorwa sechassis switch slots
- BPE slots yakaverengerwa kubva pa100 kusvika 162

- MaBPE haaite shanduko yemuno. Nekuda kweizvozvo, traffic yese inonangidzirwa kuCB uye, kana zvichidikanwa, inotumirwa kune chiteshi chiri padyo cheiyo BPE slot, inodzokera kumashure. (BPE inogamuchira pakiti, inowedzera E-TAG musoro uye inotumira kuchiteshi chepamusoro)
Kushanda seBPE, chikuva chitsva chehardware, ExtremeSwitching V400, chakaunzwa. Inosanganisira madhishi ekuwedzera e24/48 10/100/1000 Base-T madoko ane kana asina PoE rutsigiro. Models dzine 24 ports dzine maviri 10G ports, nepo mhando dzine 48 ports dzine ina 10G ports.
basa Features
Topologies ine imwe kana maviri CBs uye anosvika mana cascaded VPE maketani anotsigirwa. Cascadable ports inogona kusanganiswa kuita LAG (kusvika ku4 ports yeV400-48t / p modhi). Kupera zviteshi zvinogona kubatana kune akasiyana BPE slots uchishandisa LAG.
Kuonekwa kweBPE uye kushanda kunoenderana nemaprotocol akadai se:
- LLDP - yekutanga kuona uye kutsunga kwemhando uye kugona kweiyo yakabatana mudziyo
- ECP - "Edge Control Protocol" yekufambisa yePE-CSP
- PE-CSP - "Port Extender Control uye Status Protocol" kugadzirisa BPE kutonga neKudzora Bridge.
- LACP - kumisikidza LAG pakati pe "cascade" <-> "kumusoro" zviteshi
Kana dhizaini inoshivirira dhizaini ine maviri CBs uye MLAG ikashandiswa, ipapo kana CB imwe yadzoserwa, iyo BPE icharamba ichitumira traffic kuburikidza neyasara Kudzora Bridge. Kana iyo chete CB ikatangazve, saka BPE inodzima nekutonga madoko ayo "akawedzerwa".
Kuti zvive nyore kugadzirisa topology ine 2 CBs, kugona kugadzirisa MLAG ports yevaviri vezera kubva kune chero yeCBs yakawedzerwa. Iyo modhi inonzi "mlag orchestration", umo vezera vanowiriranisa chikamu chegadziriso chine chekuita nezvirongwa zveMLAG ports. Iyo yekumisikidza yakafanana nekumisikidza tsika "virtual-router".
