Fahmitaanka Span, RSPAN iyo Erspan: Farsamooyinka loogu talagalay kormeerka taraafikada ee shabakada

Span, RSPAN, iyo Erspan waa farsamooyin loo adeegsaday isku xirnaanta si loo qabsado loona kormeero taraafikada si loo falanqeeyo falanqaynta. Waa tan dulmar guud oo kooban oo midkasta:

Span (oo loo beddelay falanqaynta dekeda)

Ujeeddo: Waxaa loo isticmaalaa in lagu garaaco taraafikada ka yimaada dekedaha gaarka ah ama VLANs ee loo beddelo deked kale oo lagu kormeero.

Adeegso kiis: Ku habboon in la falanqaynta taraafikada taraafikada ee hal wareeg. Gaadiidka waxaa loo qorsheeyay deked loogu talagalay halkaas oo falanqeeyaha shabakadda ay qabsan karto.

RSPAN (Spant Span)

Ujeeddo: Wuxuu kordhiyaa awoodaha SPAN ee ku saabsan suuqyo badan oo shabakad ah.

U isticmaal kiiska: Waxay u oggolaaneysaa la socodka taraafikada mid ka mid ah u beddelo mid kale oo ku saabsan iskuxirka jirridda. Faa'iido u leh xaaladaha xaaladaha korjoogtada ah ee ay ku yaalliin meel kale.

Erspan (oo ay kuxirantahay Spant fog)

Ujeeddo: Waxay isku daraysaa RSPAN oo leh gre (gent lowsil huurin) si loo saadaaliyo taraafikada muraayadda.

Adeegso kiis: waxay u oggolaaneysaa la socodka taraafikada shabakadaha loo safray. Tani waxay waxtar u leedahay naqshadeeyeyaasha shabakadda ee isku-dhafka ah ee loo baahan yahay in taraafikada loo qabto in lagu qabto qaybo kala duwan.

Falanqaynta dekeda (Span) waa wax ku ool ah, nidaam korjoogteynta taraafikada taraafikada. Waxay hagantahay ama waxay muraayad ka muujisaa taraafikada deked isha ama vlan to dekedda loo socdo. Tan waxaa mararka qaarkood loo yaqaan kormeerka kalfadhiga. Span waxaa loo isticmaalaa in lagu faafiyo arrimaha isku xirnaanta iyo xisaabinta shabakadda shabakadda iyo waxqabadka, mid kale oo kale. Waxaa jira saddex nooc oo ka mid ah taageerada la taageeray ee ku saabsan wax soo saarka Cisco ...

a. Span ama span maxalli ah.

b. Spant Span (RSPAN).

c. Wasakhaysan meel fog (Erspan).

Si loo ogaado: "Xirmooyinka shabakadda ee shabakada"

Miisaaniyadda SPAN / GARGAARKA GUUD / BEDDING BONDING waxaa loo isticmaalaa ujeedooyin badan, hoosta waxaa ku jira qaar ka mid ah.

- hirgelinta Aqoonsiyada / IP-yada qaab dhismeedka.

- VOIP wac xalka duubista.

- Sababtoo ah u hoggaansanaanta amniga ee lagu kormeero oo falanqayo taraafikada.

- Dhibaatooyinka iskuxirka, la socodka taraafikada.

Iyada oo aan loo eegin Nooca Nooca Span, Isha Span waxay noqon kartaa nooc kasta oo deked ah oo dekedda jidka loo maro, dekeda loo yaqaan 'dekeda' '' dekeda '' dekeda '' 'deked', oraah loo yaqaan 'deked') iwm.

Kalfadhiyada Span waxay taageeraan korjoogteynta taraafikada taraafikada (SPAN SPAN), taraafikada EGRAS (EGESS Span), ama taraafikada labada dhinacba.

- Spans Span (RX) Nuqulo Confest waxaa helay taraafikada ay ka heleen dekedaha isha iyo VLANs dekeda meesha loo socdo. SPAN Nuqullada taraafikada ka hor wixii wax ka beddel ah (tusaale ahaan ka hor intuusan jirin wax kasta ama shaandhada aCL, QOs ama macluumaad fara badan).

- Egress Span (TX) Nuqullada ayaa laga soo qaatay gawaarida laga soo qaaday dekedaha isha iyo VLANS dekeda loo maro. Dhammaan shaandhaynta quseeya ama wax ka badalida jajabinta ama filterka acl, QOs ama falalka sinada ama falalka sicirka ee EGRAS waxaa la qaataa ka hor wareejinta taraafikada ee dekeda loo maro dekeda.

- Marka labadaba ereyga loo isticmaalo, Span nuqulo ka dib isku xirka taraafikada ayaa helay oo lagu gudbiyey dekedaha isha iyo VLANS dekeda loo socdo.

- Span / RSPAN badiyaa waa la diidayaa CDP, STP BPDU, VTP, DTP iyo PAGP GAGP. Si kastaba ha noqotee noocyadan taraafikada waa la gudbin karaa hadii taliska samafalka la dejiyo.

Span ama span maxalli ah

Span waxay ka muuqataa in taraafikada mid ama in ka badan interface ku wareejinta hal ama in ka badan oo is-dhexgal isku mid ah isla marka la socdo; Sidaa darteed Span waxaa inta badan loogu yeeraa xaafad maxalli ah.

Tilmaamaha ama xayiraadaha loo diro Span:

- Lakabka Lakabka 2 ee la beddelay iyo lakabka 3 dekedaha 3 dekedaha ayaa loo habeyn karaa inay yihiin isha ama dekedaha goobta.

- Isha isha waxay noqon kartaa mid ama in ka badan dekedo ama vl, laakiin aan ku qasin kuwan.

- Dekedaha jirridda ayaa ah dekedaha ay quseyso oo lagu qasay dekedaha aan la garaneyn.

- Illaa 64 dekedo oo kale oo dekedo ah ayaa lagu habeyn karaa beddel.

- Markaan dejinayno deked aad u socoto, qaabeynta asalka ah ayaa la daabacay. Haddii qaabeynta munaasabadda la saarayo, qaabeynta asalka ah ee dekadaas ayaa dib loo soo celiyay.

- Markaad dejiso dekedda loo socdo, dekada waxaa laga saaraa wax kasta oo ku yaal xirmooyin kasta oo Etherchalannel haddii ay qayb ka ahayd mid. Haddii ay ahayd deked la soo rogay, qaabeynta hadda la doonayo in la joojiyo qaabeynta dekedda ee loo rogay.

Dekeda dekedaha ah ma taageeraan amniga dekeda, 802.1x xaqiijinta, ama VLINs gaar loo leeyahay.

- Dekeddu waxay u dhaqmi kartaa sidii dekeda meesha loo socdo oo keliya hal kalfadhi oo keliya.

- deked laguma habeyn karo sidii deked kale oo loo maro haddii ay tahay deked isha oo ku saabsan fadhiga suulka ama qayb ka mid ah isha VLAN.

- Tartanka dekeda (ethertchalannel) waxaa loo habeyn karaa sidii dekedaha isha laakiin aan ahayn deked ay u socoto Span.

- Jihada taraafikada waa "labadaba" ee loogu talagalay ilo wareedyo Span.

- Dekedaha meesha loo socdo waligood kama qeybqaadan tusaalahan geedka-qaata. Kama taageeri karo DTP, CDP iwm. Sidaa awgeed waligaa ha ku xirin meel u beddelo noocan ah maadaama ay sababi karto shabakad loop. Aaladaha AI waxay hagaajin doontaa hufnaanta shaqada, iyoaan la ogaan karin aiAdeeggu wuxuu hagaajin karaa tayada aaladaha AI.

- Marka VLAN loo habeeyay Isha Span (oo inta badan loo yaqaan VSPAN) oo labada dhinacba ah iyo xulashooyin ah oo laga soo qaado labadaba, baakado nuqul ah oo ka socda dekada isha oo keliya haddii baakadaha lagu beddelo isla vlan. Hal koobi ah oo xirmada ah ayaa laga soo qaadayaa taraafikada ee dekeda qulqulka, oo koobiga kale ee baakadda ayaa ka socda taraafikada ee dekedda ugu badan.

- VSPAN waxay kormeertaa oo keliya taraafikada oo keliya oo ka baxda ama galaya lakabka 2 dekedaha ee VLAN.
