Intshayelelo
Olu xwebhu luchaza ngokufutshane ukusetyenziswa okusekwe kwi-CLI kweedilesi ze-DHCP ze-interface nganye, ezaziwa ngokuba ziidilesi ezigciniweyo.
Inkcazelo yoMba
Olu phawu lujolise ekuboneleleni ngesakhono sokuqwalasela i-DHCP pool kangangokuba kukho imephu ye-1: 1 phakathi kojongano lwe-Ethernet port kunye nedilesi ye-IP enikezelwa ngqo kulo jongano lwezibuko.
Usetyenziso oluphambili kuxa isixhobo sokutshintsha sinokuncamathela ngokuthe ngqo umxhasi kwizibuko ngalinye, kwiseti esezantsi yamazibuko. Kuloo meko kunokuba lula ukutshixa idilesi ye-IP yesixhobo esincanyathiselwe kwizibuko ngalinye, njengoko oku kwenza lula ukutshintshwa kwesixhobo somthengi kwindawo yemveliso: Cingela, yithi, isivamvo solunye uhlobo luncanyathiselwe kujongano lweFa 1/4 , kwaye isivamvo singasebenzi kakuhle. Umchwephesha wenkonzo uya kuqhawula ngokulula isixhobo esisilelayo, endaweni yaso kwaye aqhagamshele isixhobo esitsha-eya kuthi ke nge-DHCP ifumane kanye uqwalaselo lwe-IP olufanayo njengesixhobo esingaphumeleliyo. Kungoko, kunjalo, ukuya kwinkqubo yolawulo lwenethiwekhi ukwenza uqwalaselo olongezelelweyo lwesixhobo esitsha ukuba siyasifuna, kodwa inkqubo yolawulo lomnatha ayinyanzelekanga ngandlela ithile ukuba ikhangele inethiwekhi yesixhobo sokutshintsha i-IP.
ulwazi
Ngaphandle kwalapho kuqatshelwe khona, zonke izikhankaso zojongano zinxulumene nequla elithile. Iyasebenza kujongano olufanayo lomzimba ukuba luqukwe kwiiphuli ezininzi ezibonelela ngeenkonzo ezahlukeneyo zojongano lweVLAN. Ukuhambelana koqwalaselo kuloo meko luxanduva lomlawuli wenkqubo.
Example
- Thatha ujongano lweVLAN 42 nge IP 10.42.0.1/16
- Cinga amazibuko Fa 1/1-4 ngamalungu VLAN 42
- Cinga ukuba sidala iphuli ye-DHCP yaloo nethiwekhi, 10.42.0.0/16
- Emva koko sifuna ukukwazi ukuthi:
- I-DHCP FUMANA/ISICELO esifika `Fa 1/1` siya kufumana i-IP 10.42.1.100/16
- Kwaye kwi-Fa 1/2 iya kufumana 10.42.55.3/16
Kodwa ke kuthekani ngeFa 1/3 kunye neFa 1/4? Kuxhomekeke ekubeni ichibi liqwalaselwe ukunika kuphela iidilesi ezigciniweyo okanye hayi. Ukuba kunjalo, kuphela iidilesi ezimbini ze-Fa 1/1 kunye ne-Fa 1/2 ziyafumaneka-kwaye Fa 1/3 kunye ne-Fa 1/4 aziyi kukhonza abathengi be-DHCP.
Kwelinye icala, ukuba ichibi alitshixwanga kwiidilesi ezibekelwe, ngoko Fa 1/3 kunye Fa 1/4 uya kukhupha iidilesi non-ezigcinelwe ukusuka eseleyo free idilesi womnatha pool eqwalaselweyo, 10.42.0.0/16. Iseti yedilesi eshiyekileyo yile:
- Inethiwekhi ye-IP (10.42.0.0/16), thabatha:
- Idilesi yojongano lweVLAN, umz. 10.42.0.1
- Isethi yeedilesi ze-interface, 10.42.1.100 kunye ne-10.42.55.3
Naluphi na uluhlu lweedilesi olungabandakanywanga - (Kwaye naziphi na iidilesi esele zisebenzayo zeDHCP)
Amacandelo afanelekileyo oqwalaselo anokujongeka ngokufana noku:
# bonisa ukusebenza-config
! Ehlabathini lonke yenza umsebenzi womncedisi we-DHCP
ip dhcp iseva
! Yenza iVLAN kunye neVLAN interface eza kube isebenzela iDHCP
icandelo 42
ujongano vlan 42
idilesi ye-IP 10.42.0.1 255.255.0.0
ip dhcp iseva
! (Ulungiselelo lobulungu bePort VLAN lushiyiwe)
! Yenza ichibi
ip dhcp ichibi lam_iphuli
inethiwekhi 10.42.0.0 255.255.0.0
usasazo 10.42.255.255
qeshisa i-1
! Chaza iidilesi zojongano ngalunye lweFa 1/1 kunye neFa 1/2:
idilesi 10.42.1.100 ujongano FastEthernet 1/1
idilesi 10.42.55.3 ujongano FastEthernet 1/2
! nikezela kuphela ngeedilesi zojongano ngalunye:
! ebekelwe-kuphela
! Okanye unikezele ngazo zombini iidilesi ze-interface kunye needilesi eziqhelekileyo eziguqukayo
! akukho obekelwe-kuphela
Ebekelwe-Kuphela vs. Ayigcinwanga-Kuphela
Olu qwalaselo lungentla lunokuzekeliswa ngolu hlobo lulandelayo. I-DHCP Server Switch inonxibelelwano oluninzi kunye nabaxhasi abancanyathiselwe. Omnye wabo bathengi ngumaleko olula we-2 we-ethernet switch kunye nabaxhasi abathathu abaqhotyoshelweyo. Iindibano ezimbini zokuqala kwi-DHCP Server Switch zinikezela ngeedilesi ze-interface nganye, kwaye ujongano oluseleyo lunika iidilesi ezikhoyo ukusuka echibini.
ULWAZI
Utshintsho lweLayer 2 luthathwa ngokuba ne-IP engatshintshiyo.
Umzobo 1. Iqula elineedilesi ze-Per-Interface, Ayigcinwanga-Kuphela
Ukuba, nangona kunjalo, i-pool ibekwe kwimodi egciniweyo kuphela, kuphela ngabaxhasi ababini abaqhotyoshelwe kwi-Fa 1/1 kunye ne-Fa 1/2 baya kunikwa iidilesi:
Tshintsha # ukumisela iitheminali
Tshintsha(config)# ip dhcp pool yam_iphuli
Tshintsha(config-dhcp-pool)# ebekelwe-kuphela
Tshintsha(config-dhcp-pool)# ekupheleni
Umzobo 2. Iqula elineedilesi ze-Per-Interface, eziGciniweyo-Kuphela
Oku kuya kusebenza kwakhona ukuba umaleko wesi-2 uqhagamshelwe kumzekelo.
Umzobo 3. Iqula elineedilesi zomNxibelelwano ngamnye, Tshintshela kwisiZibuko soBunxibelelanisi obuNganye
Ukuba ichibi aligcinwanga-kuphela, imeko efanayo iyasebenza kubathengi be-L2 Tshintsha: Inye kuphela kubo eya kunikwa idilesi, ngelixa abathengi beqhagamshelwe ngokuthe ngqo kwi-DHCP Server Switch kujongano ngaphandle kwedilesi yojongano-nganye baya kuthi bonke. zinikwe iidilesi equleni.
Umzobo 4. Iqula elineedilesi ze-Per-Interface, Ayigcinwanga-Kuphela
Kulo mzekelo abathengi abathathu encanyathiselwe kwi Layer 2 iswitsha baya kukhuphisana idilesi ekhoyo kuphela ezinikezelwa yi Fa 1/1 kwi DHCP Umncedisi Switch. Ngokuqhelekileyo ayigqibeki ukuba yeyiphi isixhobo "esiphumeleleyo", ngoko ke olu lungelelwaniso kufuneka luphetshwe.
Uqwalaselo
Iidilesi ze-interface nganye ziyafumaneka kwii-DHCP pools zohlobo lwe-'network' kuphela. Azenzi ngqiqweni kumachibi okubamba, njengoko lawo anedilesi enye kuphela enokunikezela ngayo.
Le miyalelo mine ilandelayo yoqwalaselo iyafumaneka kwi-DHCP pool yokumisela imowudi engaphantsi:
Uluhlu loku-1. Imiyalelo yoqwalaselo lwedilesi ye-Per-Interface
| Umyalelo | Inkcazo |
| idilesi ujongano | Yenza/ulungise ungeno lwedilesi yojongano ngalunye. |
| akukho dilesi | Cima ungeniso lwedilesi yojongano ngalunye. |
| ebekelwe-kuphela | Nikela ngeedilesi zojongano ngalunye. |
| akukho obekelwe-kuphela | Nikeza zombini iidilesi ze-interface kunye needilesi eziqhelekileyo eziguquguqukayo ukusuka echibini. |
Le migaqo ilandelayo iyasebenza:
- Ujongano lunokuba nedilesi enye kuphela ye-interface nganye
- Zonke iidilesi ze-interface nganye kufuneka zizodwa
- Ujongano olunedilesi yojongano ngalunye luya kubonelela ngedilesi enye kuphela kubaxhasi
- Idilesi ye-interface nganye kufuneka ibe yeyothungelwano lwe-pool
Le migaqo ingasentla yeyophuli-mthetho nganye. Izibuko elithile eliphathekayo linokuba lilungu leeVLAN ezahlukeneyo kunye namachibi ahlukeneyo, kwaye unikeze ngeedilesi ezahlukeneyo zojongano ngalunye kwiqula ngalinye.
Ukutshintsha ulungelelwaniso lwedilesi ye-interface nganye kwiqula elikhoyo linokwenza ukuba izibophelelo ezikhoyo zingasebenzi.
Imigaqo elawula ukuphela kwexesha elibophelelayo yile:
- ebekelwe kuphela ⇒ hayi kugcinelwe kuphela : Gcina izibophelelo, iidilesi ezininzi ezikhoyo ziyakhula.
- hayi ebekelwe kuphela ⇒ ebekelwe-kuphela : Coca zonke izibophelelo
- Yongeza okanye Guqula idilesi ye-interface nganye: Coca zonke izibophelelo; inokuba yi IP esele isetyenziswa, okanye ujongano nezinye, ezisebenzayo, izibophelelo
- Cima idilesi yojongano-ndlela: Cima isibophelelo saloo dilesi kuphela
- Ikhonkco-phantsi kwi-interface enedilesi ye-per-interface: Coca isibophelelo. Oku kuqinisekisa ukuba imeko yokutshintshwa kwesixhobo somthengi esiqhagamshelwe ngokuthe ngqo siyasebenza: Xa isixhobo asiphumelelanga sisusiwe, ikhonkco-phantsi liyalandela. Xa isixhobo sokutshintsha sisebenza kwaye uqhagamshelo luqhubeleka, esi sixhobo siya kufumana idilesi yojongano ngalunye.
Ukongeza ingeniso egciniweyo kujongano olunabathengi abaninzi abakhoyo kuthetha ukuba abaxumi abakhoyo abayi kukwazi ukuhlaziya izibophelelo zabo; kufuneka bakhuphisane ngedilesi enye ekhoyo kujongano. Oku kuya kushiya konke ngaphandle komxhasi omnye ngaphandle kwe-DHCPserved IP.
Ukubeka iliso
Iidilesi ze-per-interface azizisi miyalelo mitsha yokubeka iliso, kodwa zandisa nje imveliso evela kwimiyalelo ethile yokubeka iliso kwi-DHCP.
Uluhlu loku-2. Imiyalelo yokuJonga idilesi ye-Per-Interface
| Umyalelo | Inkcazo |
| bonisa ip dhcp pool [ ] | Bonisa ulwazi lwe-pool nganye. Onke amadama adweliswe ukuba igama_lichibiyelwe alifakwanga. |
| bonisa i-ip dhcp iseva ebophelelayo […] | Bonisa ulwazi olubophelelayo. Izihluzo ezininzi ziyafumaneka, zokucoca kwimeko kunye/okanye uhlobo. |
