Chitsimikizo
Microsemi sapereka chitsimikizo, choyimira, kapena chitsimikizo chokhudza zomwe zili m'nkhaniyi kapena kuyenerera kwa katundu ndi ntchito zake pazifukwa zinazake, komanso Microsemi sakhala ndi udindo uliwonse chifukwa cha ntchito kapena kugwiritsa ntchito mankhwala kapena dera lililonse. Zogulitsa zomwe zimagulitsidwa apa ndi zina zilizonse zomwe zimagulitsidwa ndi Microsemi zakhala zikuyesedwa pang'ono ndipo siziyenera kugwiritsidwa ntchito limodzi ndi zida zofunikira kwambiri kapena ntchito. Zochita zilizonse zimakhulupirira kuti ndizodalirika koma sizinatsimikizidwe, ndipo Wogula amayenera kuchita ndikumaliza ntchito zonse ndi kuyesa kwina kwazinthuzo, payekha komanso, kapena kuyikamo, zogulitsa zilizonse. Wogula sadzadalira deta iliyonse ndi machitidwe kapena magawo operekedwa ndi Microsemi. Ndiudindo wa Wogula kuti adziyese yekha ngati zogulitsa zilizonse ndi kuyesa ndikutsimikizira zomwezo. Zomwe zimaperekedwa ndi Microsemi pansipa zimaperekedwa "monga momwe zilili, zili kuti" komanso zolakwa zonse, ndipo chiopsezo chonse chokhudzana ndi chidziwitso choterocho chiri kwathunthu ndi Wogula. Microsemi sapereka, momveka bwino kapena momveka bwino, kwa chipani chilichonse ufulu wa patent, zilolezo, kapena ufulu wina uliwonse wa IP, kaya ndi chidziwitso chokhacho kapena chilichonse chofotokozedwa ndi izi. Chidziwitso choperekedwa m'chikalatachi ndi cha Microsemi, ndipo Microsemi ali ndi ufulu wosintha zomwe zili mu chikalatachi kapena pazinthu zilizonse ndi mautumiki nthawi iliyonse popanda chidziwitso.

Mawu Oyamba
Chikalatachi chikufotokoza mwachidule kagwiritsidwe ntchito ka CLI ka ma adilesi a DHCP pa-interface, omwe amadziwikanso kuti ma adilesi osungidwa.
Kufotokozera Kwazinthu
Izi zikufuna kupereka mwayi wokonza dziwe la DHCP kuti pakhale mapu a 1:1 pakati pa mawonekedwe a doko la Efaneti ndi adilesi ya IP yoperekedwa pa doko lomwelo.
Chomwe chimagwiritsa ntchito kwambiri ndi pomwe chosinthira chimakhala ndi kasitomala m'modzi wolunjika padoko, pamadoko ena. Zikatero kungakhale kothandiza kutseka adilesi ya IP ya chipangizocho chomwe chimalumikizidwa ku doko lililonse, chifukwa izi zimathandizira kusinthana kwa chipangizo cha kasitomala pamalo opangira: Tangoganizani, titi, sensor yamtundu wina imalumikizidwa ndi mawonekedwe a Fa 1/4, ndi kulephera kwa sensor. Katswiri wautumiki amangochotsa chipangizocho cholephera, m'malo mwake ndikulumikiza chipangizo chatsopanocho, chomwe pambuyo pake kudzera pa DHCP chidzalandila kukhazikitsidwa kwa IP komweko monga chipangizo cholephera. Ndiye, ndithudi, mpaka dongosolo kasamalidwe maukonde kuchita kasinthidwe zina latsopano chipangizo ngati pakufunika izo, koma osachepera makina kasamalidwe dongosolo alibe mwanjira kufufuza maukonde kwa chipangizo m'malo IP.
zambiri
Pokhapokha pamene zadziwika bwino, zotchulidwa zonse za mawonekedwe akukhudzana ndi dziwe linalake. Ndizovomerezeka kuti mawonekedwe omwewo aphatikizidwe m'mayiwe angapo omwe amagwiritsa ntchito ma VLAN osiyanasiyana. Kusasinthika kwadongosolo pankhaniyi ndi udindo wa woyang'anira dongosolo.
Example
- Lingalirani mawonekedwe a VLAN 42 okhala ndi IP 10.42.0.1/16
- Tangoganizani madoko a Fa 1/1-4 ndi mamembala a VLAN 42
- Tiyerekeze kuti tikupanga dziwe la DHCP lamanetiweki, 10.42.0.0/16
- Kenako tikufuna kunena kuti:
- KUDZIWA KWA DHCP/KUPEMPHA kukafika pa `Fa 1/1` kudzalandira IP 10.42.1.100/16
- Ndipo pa Fa 1/2 idzalandira 10.42.55.3/16
Koma nanga bwanji Fa 1/3 ndi Fa 1/4 ? Zimatengera ngati dziwe lakonzedwa kuti lingopereka ma adilesi osungidwa kapena ayi. Ngati zili choncho, maadiresi awiri okha a Fa 1/1 ndi Fa 1/2 ndi omwe alipo—ndipo Fa 1/3 ndi Fa 1/4 sizithandiza makasitomala a DHCP.
Kumbali ina, ngati dziwe silinatsekedwe ku ma adilesi osungidwa, ndiye Fa 1/3 ndi Fa 1/4 adzapereka maadiresi osasungidwa kuchokera ku maadiresi aulere otsala a netiweki ya dziwe, 10.42.0.0/16. Ma adilesi otsala ndi awa:
- Netiweki ya IP (10.42.0.0/16), kuchotsera:
- Adilesi ya mawonekedwe a VLAN, mwachitsanzo 10.42.0.1
- Seti ya ma adilesi amtundu uliwonse, 10.42.1.100 ndi 10.42.55.3
Ma adilesi aliwonse osaphatikizidwa - (Ndi ma adilesi aliwonse omwe ali kale a DHCP)
Zigawo zofananira za kasinthidwe zitha kuwoneka ngati izi:

Reserved-Only vs. Not Reserved-Only
Kukonzekera pamwambaku kungafotokozedwe motere. DHCP Server Switch ili ndi zolumikizira zambiri ndi makasitomala omwe ali nawo. Mmodzi mwamakasitomalawo ndi masinthidwe osavuta a 2 ethernet okhala ndi makasitomala atatu olumikizidwa. Mawonekedwe awiri oyambirira pa DHCP Server Switch amapereka maadiresi amtundu uliwonse, ndipo malo otsalawo amapereka maadiresi omwe alipo kuchokera padziwe.
INFO
The Layer 2 Switch imaganiziridwa kuti ili ndi IP yokhazikika.
Chithunzi 1. Phulu Lokhala Ndi Maadiresi Amtundu Wanu, Osasungidwa-Okha
Ngati, komabe, dziwe litayikidwa munjira yosungidwa, makasitomala awiri okha omwe ali ndi Fa 1/1 ndi Fa 1/2 ndi omwe adzapatsidwe ma adilesi:
Sinthani # sinthani terminal
Sinthani(config)# ip dhcp dziwe my_pool
Sinthani(config-dhcp-pool)# reserved-only
Switch(config-dhcp-pool)# end
Chithunzi 2. Phulu Lokhala Ndi Maadiresi A Per-Interface, Osungidwa-Okha
Izi zitha kugwiranso ntchito ngati chosinthira cha 2 chidalumikizidwa ndi mwachitsanzo Fa 1/1: Mmodzi yekha mwamakasitomala ake ndi omwe angapatsidwe adilesi yachiwonekedwe:
Chithunzi 3. Dziwe Lokhala Ndi Maadiresi Amtundu Wanu, Sinthani Per-Interface Port
Ngati dziwe silinasungidwe kokha, zomwezo zimagwiranso ntchito kwa makasitomala a L2 Switch: Mmodzi yekha wa iwo adzapatsidwa adiresi, pamene makasitomala olumikizidwa mwachindunji ndi DHCP Server Switch pa interfaces popanda adiresi iliyonse. kuperekedwa maadiresi kuchokera dziwe.
Chithunzi 4. Phulu Lokhala Ndi Maadiresi Amtundu Wanu, Osasungidwa-Okha
Pamenepa makasitomala atatu omwe ali pa switch ya Layer 2 adzapikisana pa adilesi yokhayo yomwe ilipo yoperekedwa ndi Fa 1/1 pa DHCP Server switch. Nthawi zambiri sizodziwika kuti ndi chipangizo chotani "chopambana", kotero kasinthidwe kumeneku kuyenera kupewedwa.
Kusintha
Maadiresi amtundu uliwonse amapezeka pamitundu ya DHCP yamtundu wa 'network' yokha. Sizomveka kwa maiwe olandirira alendo, chifukwa omwe ali ndi adilesi imodzi yokha yoti apereke.
Malamulo anayi otsatirawa akupezeka mu DHCP pool configuration sub-mode:
Table 1. Malamulo Okonzekera Maadiresi a Per-Interface
| Lamulo | Kufotokozera |
| adilesi mawonekedwe | Pangani/sinthani adilesi yachiyankhulo chilichonse. |
| palibe adilesi | Chotsani adilesi yamitundu yonse. |
| zosungidwa-zokha | Perekani ma adilesi amtundu uliwonse. |
| palibe zosungidwa-zokha | Perekani maadiresi amitundu yonse ndi maadiresi osinthika kuchokera padziwe. |
Malamulo otsatirawa akugwira ntchito:
- Mawonekedwe amatha kukhala ndi adilesi imodzi yokha pa-interface
- Maadiresi onse a pa interface ayenera kukhala apadera
- Mawonekedwe okhala ndi adilesi yapa-interface amangopereka adilesi imodzi kwa makasitomala
- Adilesi yapa-interface iyenera kukhala ya netiweki yamadzi
Malamulo omwe ali pamwambawa ndi pa dziwe. Doko linalake lakuthupi limatha kukhala membala wa ma VLAN osiyanasiyana ndi maiwe osiyanasiyana, ndikupereka ma adilesi osiyanasiyana pamayendedwe osiyanasiyana padziwe lililonse.
Kusintha machunidwe a adilesi yapa-interface pa dziwe lomwe lilipo kale kulepheretsa zomangira zomwe zilipo kale.
Malamulo oyendetsera kutha kwa ntchito ndi awa:
- osungika okha ⇒ osasungidwa-okha : Sungani zomangira, ma adilesi omwe alipo amangokulirakulira.
- osasungidwa-okha zosungidwa-zokha : Chotsani zomangira zonse
- Onjezani kapena Sinthani adilesi ya mawonekedwe: Chotsani zomangira zonse; ikhoza kukhala IP yomwe ikugwiritsidwa ntchito kale, kapena mawonekedwe ndi zina, zomangika, zomangika
- Chotsani adilesi yachiwonekedwe: Chotsani zomangira za adilesiyo yokha
- Lumikizani pansi pamawonekedwe okhala ndi adilesi yapa-interface: Chotsani chomangira. Izi zimawonetsetsa kuti cholumikizira cha kasitomala cholumikizidwa mwachindunji chimagwira ntchito: Chida cholephera chikachotsedwa, ulalo-pansi umayamba. Chipangizo cholowa m'malo chikayimitsidwa ndikulumikizana ndi kulumikizana, chipangizochi chidzapeza adilesi yachiyankhulidwe chilichonse.
Kuyika malo osungika pamawonekedwe omwe ali ndi makasitomala angapo omwe alipo kukutanthauza kuti makasitomala omwe alipo sangathe kukonzanso zomangira; ayenera kupikisana pa adilesi imodzi yomwe ilipo pa mawonekedwe. Izi zidzasiya onse kupatula kasitomala mmodzi wopanda DHCPserved IP.
Kuwunika
Maadiresi amtundu uliwonse samawonetsa malamulo atsopano owunikira, koma amangowonjezera zotuluka kuchokera ku malamulo ena owunika a DHCP.
Table 2. Per-Interface Adilesi Monitoring Commands
