SPAN
Waxaad isticmaali kartaa shaqada SPAN si aad u nuquliso baakadaha laga soo qaadayo deked gaar ah una wareejiso deked kale oo ku taal badhanka oo ku xiran qalabka la socodka shabakadda si loola socdo loona xalliyo dhibaatooyinka shabakadda.
SPAN saameyn kuma yeelato is-weydaarsiga baakadaha ee u dhexeeya dekedda isha iyo dekedda loo socdo. Dhammaan baakadaha soo galaya iyo kuwa ka soo baxaya dekedda isha waxaa lagu koobiyeeyaa dekedda loo socdo. Si kastaba ha ahaatee, haddii taraafikada muraayadda leh ay ka badan tahay baaxadda dekedda loo socdo, tusaale ahaan, haddii dekedda loo socdo ee 100Mbps ay la socoto taraafikada dekedda isha ee 1000Mbps, baakadaha waa la tuuri karaa.
RSPAN
Muraayadda dekedda fog (RSPAN) waa kordhinta muraayadda dekedda maxalliga ah (SPAN). Muraayadda dekedda fog waxay jebinaysaa xaddidaadda ah in dekedda isha iyo dekedda loo socdo ay ku jiraan isla aaladda, taasoo u oggolaanaysa dekedda isha iyo dekedda loo socdo inay ku fidsanaadaan aalado badan oo shabakadeed. Sidan, maamulaha shabakadu wuxuu ku fadhiisan karaa qolka qalabka dhexe oo uu ku daawan karaa xirmooyinka xogta dekedda muraayadda fog iyada oo loo marayo falanqeeyaha.
RSPANWaxay dhammaan baakadaha muraayadaha leh u gudbisaa dekedda loo socdo ee qalabka muraayadda fog iyada oo loo marayo RSPAN VLAN gaar ah (oo loo yaqaan VLAN-ka fog). Doorka qalabku wuxuu u qaybsan yahay saddex qaybood:
1) Beddelka Isha: Dekedda isha sawirka fog ee badhanka, waxay mas'uul ka tahay nuqul ka mid ah farriinta dekedda isha ee ka timaadda wax soo saarka dekedda wax soo saarka badhanka isha, iyada oo loo marayo gudbinta VLAN-ka fog, u gudbi bartamaha ama u beddel.
2) Beddelka Dhexdhexaadka ah: shabakadda u dhaxaysa badhanka isha iyo meesha loo socdo, beddel, muraayad iyada oo loo marayo gudbinta baakadka VLAN ee fog ilaa kan xiga ama si loogu beddelo bartamaha. Haddii badhanka isha si toos ah ugu xiran yahay badhanka loo socdo, ma jiro beddel dhexdhexaad ah.
3) Beddelka Meesha Loo Socdo: Dekedda meesha loo socdo ee muraayadda fog, muraayadda laga bilaabo VLAN-ka fog si aad farriin uga hesho dekedda loo socdo ee muraayadda si aad ula socoto qalabka.
ERSPAN
Muraayadda Dekedda Fog ee La Duubay (ERSPAN) waa fidinta muraayadda dekedaha fog (RSPAN). Kalfadhiga muraayadda dekedaha fog ee caadiga ah, baakadaha muraayadda leh waxaa lagu gudbin karaa oo keliya Lakabka 2 mana dhex mari karaan shabakad la rogay. Kalfadhiga muraayadda dekedaha fog ee la duubay, baakadaha muraayadda leh waxaa lagu gudbin karaa shabakadaha la rogay.
ERSPAN waxay ku soo ururisaa dhammaan baakadaha muraayadaha leh baakadaha IP-ga iyada oo loo marayo tunnel GRE ah waxayna u gudbisaa dekedda loo socdo ee qalabka muraayadda fog. Doorka qalab kasta waxaa loo qaybiyaa laba qaybood:
1) Beddelka Isha: kaydinta sawirka fog ee dekedda isha ee badhanka, ayaa mas'uul ka ah nuqul ka mid ah farriinta dekedda isha ee ka timaadda wax soo saarka dekedda wax soo saarka ee badhanka isha, iyada oo loo marayo GRE ku lifaaqan gudbinta baakadka IP-ga, wareejinta badhanka ujeeddada.
2) Beddelka Meesha Loo Socdo: kaydinta muraayadda fog ee dekedda meesha loo socdo ee badhanka, waxay fariinta ka heli doontaa muraayadda muraayadda ee dekedda loo socdo, ka dib marka la furo, fariinta GRE ee loo gudbiyo si loola socdo qalabka.
Si loo hirgeliyo shaqada muraayadda dekedda fog, xirmooyinka IP-ga ee ay ku dahaaran tahay GRE waa in loo wareejiyaa qalabka muraayadda ee loo socdo ee shabakadda.
Soo saarista Xirmooyinka Baakadaha
Waxaa lagu taageerayaa in lagu soo koobo baakad kasta oo gaar ah oo ku jirta taraafikada la qabtay cinwaanka RSPAN ama ERSPAN oo lagu soo saaro baakadaha nidaamka kormeerka dambe ama badhanka shabakadda
Joojinta Xirmooyinka Tunnelka
Waxay taageertay shaqada joojinta baakadaha tunnelka, taas oo habayn karta cinwaanada IP-ga, maaskaro, jawaabaha ARP, iyo jawaabaha ICMP ee dekedaha gelinta taraafikada. Taraafikada laga ururinayo shabakadda isticmaalaha waxaa si toos ah loogu diraa qalabka iyada oo loo marayo hababka kaydinta tunnelka sida GRE, GTP, iyo VXLAN
Xariijimaha Madaxa ee VxLAN, VLAN, GRE, MPLS
Waxaa taageeray cinwaanka VxLAN, VLAN, GRE, MPLS oo laga saaray baakaddii xogta asalka ahayd iyo wax soo saarka la gudbiyay.
