Extreme Extended Edge (tseem hu ua Virtual Port Extender - VPEX) yog cov thev naus laus zis tshiab uas tau tshaj tawm thawj zaug hauv EXOS operating system nrog tso tawm 22.5. Kev daws nws tus kheej yog raws li IEEE 802.1BR (Bridge Port Extension) tus qauv, thiab ua ib feem ntawm EXOS 22.5 tso tawm, kev txhawb nqa rau ExtremeSwitching V400 kho vajtse tshiab kab tau ntxiv.
"VPEX Choj" yog qhov hloov pauv virtual uas muaj cov khoom siv xws li Controlling Choj (CB) thiab Choj Chaw Txuas Ntxiv (BPE). Txhawm rau ua kom muaj kev zam txim txhaum cai, nws tuaj yeem txuas mus rau ob lub CBs hauv ib qho kev hloov pauv virtual siv MLAG thev naus laus zis. Tus tsim ntawm xws li ib tug virtual hloov yog reminiscent ntawm classic chassis hloov los yog pawg ntawm cov keyboards. Thiab yog hais tias nyob rau hauv lub logic ntawm "Control Plane" ua hauj lwm no yog ntau los yog tsawg muaj tseeb, ces cov hauj lwm ntawm "Data Plane" txawv heev radically. Tom qab tag nrho, lub hom phiaj ntawm 802.1br yog txhawm rau txuas qhov chaw nres nkoj chaw taws teeb mus rau MAC hauv zos (Media Access Control) kev pabcuam, thaum cais tsheb khiav los ntawm cov chaw nres nkoj tej thaj chaw deb.
Tswj choj
- Ib thiab tsuas yog tswj taw tes
- Txhua qhov kev teeb tsa tshwm sim hauv zos ntawm CB
- VPEX kev txhawb nqa yuav tsum tau qhib, yuav tsum rov pib dua los hloov hom kev ua haujlwm
- CB yeej ib txwm qhov #1
- Hauv kev tso tawm tam sim no, CB txhawb kev sib txuas ib txhij txog li 48 BPE
- CB hom tau txais kev txhawb nqa ntawm qee qhov kho vajtse platforms (tam sim no X670G2 thiab X690, lwm lub platform yuav raug ntxiv thaum lawv tso tawm)
- EXOS daim ntawv tso cai tsuas yog siv rau SV
- VPEX tsis tas yuav muaj ntawv tso cai ntxiv
- Tag nrho lub luag hauj lwm rau cov ntaub ntawv-dav hlau ua thiab lim cov tsheb khiav
- Muaj cov sawv cev virtual ntawm txhua qhov chaw nres nkoj "extended".
Choj Chaw nres nkoj Extender
- Cov khoom siv BPE tau tswj hwm raws li chassis hloov qhov
- BPE slots raug suav los ntawm 100 txog 162

- BPEs tsis ua kev hloov hauv zos. Yog li ntawd, tag nrho cov tsheb khiav mus rau CB thiab, yog tias tsim nyog, xa mus rau qhov chaw nres nkoj uas nyob ib sab ntawm tib BPE qhov, rov qab los. (BPE tau txais cov pob ntawv, ntxiv E-TAG header thiab xa mus rau qhov chaw nres nkoj sab saud)
Txhawm rau ua haujlwm raws li BPE, lub platform kho vajtse tshiab, ExtremeSwitching V400, tau qhia. Nws suav nrog cov chaw nres nkoj nthuav dav rau 24/48 10/100/1000 Base-T chaw nres nkoj nrog lossis tsis muaj kev txhawb nqa PoE. Cov qauv nrog 24 chaw nres nkoj muaj ob lub 10G chaw nres nkoj, thaum cov qauv nrog 48 chaw nres nkoj muaj plaub 10G chaw nres nkoj.
ua hauj lwm nta
Topologies nrog ib los yog ob lub CBs thiab txog li plaub cascaded VPE chains tau txais kev txhawb nqa. Cascadable ports tuaj yeem ua ke rau hauv LAG (txog 4 qhov chaw nres nkoj rau V400-48t / p qauv). Cov chaw nres tsheb kawg tuaj yeem txuas rau BPE qhov sib txawv siv LAG.
BPE nrhiav thiab ua haujlwm yog ua raws li cov txheej txheem xws li:
- LLDP - thawj qhov kev tshawb nrhiav thiab kev txiav txim siab ntawm hom thiab muaj peev xwm ntawm cov cuab yeej txuas nrog
- ECP - "Edge Control Protocol" thauj rau PE-CSP
- PE-CSP - "Port Extender Control and Status Protocol" configuring BPE control with Controlling Choj
- LACP β teeb tsa LAG ntawm βcascadeβ <β> βsab sauvβ chaw nres nkoj
Yog tias qhov kev tsim ua txhaum cai nrog ob lub CBs thiab MLAG raug siv, tom qab ntawd thaum ib qho CB tau rov pib dua, BPE yuav txuas ntxiv xa cov tsheb khiav mus los ntawm qhov txuas txuas ntxiv. Yog tias tsuas yog CB reboots, ces BPE yuav tswj xyuas nws cov chaw nres nkoj "ntxiv" txuas.
Rau qhov yooj yim ntawm kev teeb tsa lub topology nrog 2 CBs, lub peev xwm los teeb tsa MLAG chaw nres nkoj ntawm ob tus phooj ywg los ntawm ib qho ntawm CBs tau ntxiv. Hom yog hu ua "mlag orchestration", uas cov phooj ywg synchronize ib feem ntawm config ntsig txog cov chaw ntawm MLAG ports. Kev teeb tsa zoo ib yam li teeb tsa kev cai "virtual-router".

Qhov kev ua haujlwm "Controlling Choj" muaj nyob tom qab kev txhim kho cov qauv pub dawb rau EXOS, uas muaj qhov txuas ntxiv .xmod. Tib lub module no muaj cov duab hloov tshiab rau BPE. Qhov tseeb, thaum CB thiab BPE kuaj pom ib leeg, CB kuaj xyuas cov firmware version ntsia ntawm BPE thiab, yog tias tsim nyog, hloov kho nws.
Cov haujlwm saum toj no ua rau nws tuaj yeem hloov BPE qhov yooj yim thiab sai li sai tau yog tias tsim nyog. Txij li thaum BPE slots tsis khaws ib qho kev teeb tsa thiab tsis cuam tshuam nrog txhua txoj hauv kev, tam sim ntawd tom qab hloov lub cuab yeej thiab tig lub zog, BPE yuav raug kuaj pom los ntawm SV thiab cov teeb tsa uas twb muaj lawm yuav raug siv, thiab yog tias lub firmware yog kho tshiab.
Qhov kev daws teeb meem no yog qhov zoo rau cov tes hauj lwm nrog cov kev taw qhia tseem ceeb hauv North / South, xws li cov tsev kawm ntawv hauv tsev kawm ntawv, kev lag luam network hauv kev xa khoom, kev kawm, cov chaw lag luam thiab lwm yam. Thiab peb rov hais dua ib zaug ntxiv tias qhov zoo ntawm cov tes hauj lwm tsim los ntawm "Extended Edge" kev daws teeb meem yuav yog:
- Txo tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm ib txwm network architecture los ntawm kev teeb tsa thiab kev tswj xyuas
- Yooj yim rau scale thiab deploy
- Tsis tas yuav muaj kev sib koom siab console lossis OOB Mgmt txuas rau BPE qhov
- Txo daim ntawv tso cai (yog tias tsim nyog, tsuas yog siv rau NE)
- Ib qho taw qhia ntawm kev teeb tsa, saib xyuas thiab daws teeb meem
- Tso rau hauv NMS ua ib qho kev hloov
- Tsis tas yuav muaj kev cob qhia ntxiv lossis nthuav cov neeg ua haujlwm
