Kugadzirisa 802.1X paCisco Swichi Uchishandisa Failover NPS (Windows RADIUS ine AD)

Kugadzirisa 802.1X paCisco Swichi Uchishandisa Failover NPS (Windows RADIUS ine AD)
Ngatifungei mukuita mashandisirwo eWindows Active Directory + NPS (2 maseva kuti ave nechokwadi chekushivirira) + 802.1x chiyero chekutonga kwekuwana uye kuvimbiswa kwevashandisi - domain makomputa - zvishandiso. Iwe unogona kujairana nedzidziso zvinoenderana neyakajairwa paWikipedia, pane chinongedzo: IEEE 802.1X

Sezvo "rabhoritari" yangu ishoma mune zviwanikwa, mabasa eNPS uye domain controller anowirirana, asi ini ndinokurudzira kuti uchiri kuparadzanisa masevhisi akakosha akadaro.

Ini handizive nzira dzakajairwa dzekuwiriranisa Windows NPS zvigadziriso (mitemo), saka isu tichashandisa PowerShell zvinyorwa zvakatangwa neanoronga basa (munyori ndiye wandaimboshanda naye). Nekuda kwechokwadi chedomeini makomputa uye nemidziyo isingagone 802.1x (mafoni, maprinta, nezvimwewo), mutemo weboka uchagadziriswa uye mapoka ekuchengetedza achagadzirwa.

Pakupera kwechinyorwa, ini ndichakuudza nezve mamwe maomero ekushanda ne802.1x - mashandisiro aungashandisa switch isina kutariswa, dynamic ACLs, nezvimwe. Ini ndichagovera ruzivo nezve "glitches" yakabatwa .. .

Ngatitange nekuisa nekugadzirisa failover NPS paWindows Server 2012R2 (zvese zvakafanana muna 2016): kuburikidza neSeva Maneja -> Wedzera Mabasa uye Zvimiro Wizard, sarudza chete Network Policy Server.

kana kushandisa PowerShell:

Kujekesa kudiki - kubva kune Protected EAP (PEAP) iwe zvechokwadi uchada chitupa chinosimbisa huchokwadi hwesevha (ine kodzero dzakakodzera dzekushandisa), iyo inovimbwa pamakomputa evatengi, ipapo iwe ungangoda kuisa iro basa. Certification Chiremera. Asi isu tichafungidzira kuti CA watova nayo kare...

Ngatiite zvimwechete pasevha yechipiri. Ngatigadzire folda yeC: Scripts script pamaseva ese uye network folda pane yechipiri server SRV2NPS-config$

Ngatigadzirei PowerShell script pane yekutanga server C:ScriptsExport-NPS-config.ps1 nezvinotevera zvirimo:

Export-NpsConfiguration -Path "SRV2NPS-config$NPS.xml"

Mushure meizvi, ngatigadzirise basa muTask Sheduler: "Export-NpsConfiguration"

powershell -executionpolicy unrestricted -f "C:ScriptsExport-NPS-config.ps1"

Mhanya kune vese vashandisi - Mhanya nekodzero dzepamusoro
Zuva nezuva - Dzokorora basa racho maminetsi ega ega. mukati maawa 10

PaNPS yekuchengetedza, gadzirisa kunze kwekugadzirisa (mitemo):
Ngatigadzirei PowerShell script:

echo Import-NpsConfiguration -Path "c:NPS-configNPS.xml" >> C:ScriptsImport-NPS-config.ps1

uye basa rekuita maminetsi ega ega gumi:

powershell -executionpolicy unrestricted -f "C:ScriptsImport-NPS-config.ps1"

Mhanya kune vese vashandisi - Mhanya nekodzero dzepamusoro

Zvino, kuti titarise, ngatiwedzere kuNPS pane imwe yemaseva (!) mashoma ekuchinja muRADIUS vatengi (IP uye Yakagovaniswa Chakavanzika), maviri ekubatanidza chikumbiro marongero: WIRED-Connect (Mamiriro: "NAS port type is Ethernet") uye WiFi-Enterprise (Mamiriro: "NAS port type iIEEE 802.11"), pamwe netiweki mutemo Svika Cisco Network Devices (Network Admins):

Kugadzirisa 802.1X paCisco Swichi Uchishandisa Failover NPS (Windows RADIUS ine AD)

Magadzirirwo akajairika eiyo switch port (ndapota cherechedza kuti iyo "multi-domain" yechokwadi mhando inoshandiswa - Data & Voice, uye pane zvakare mukana wekugonesa ne mac kero. Munguva ye "nguva yekuchinja" zvine musoro kushandisa mune iyo parameters:

authentication event no-response action authorize vlan 100

Iyo vlan id haisi "yekuvharirwa" imwe, asi imwe chete iyo komputa yemushandisi inofanira kuenda mushure mekubudirira kupinda mukati - kusvika tave nechokwadi chekuti zvese zviri kushanda sezvazvinofanirwa. Aya maparamendi mamwe chete anogona kushandiswa mune mamwe mamiriro, semuenzaniso, kana switch isina kutariswa ikabairwa muchiteshi ichi uye iwe unoda kuti zvishandiso zvese zvakabatanidzwa pairi izvo zvisina kupfuura huchokwadi kuti zviwire mune imwe vlan ("quarantine").

Nokudaro, tichabvumira kushandiswa kwema kero emudziyo semapassword. Mushure meizvi isu tinogona kugadzira network policy ye802.1x nzira mab authentication, ngatitii neag-devices-8021x-voice. The parameters ndeaya anotevera:

Mushure mekubudirira kwechokwadi (usakanganwa kugadzirisa switch port), ngatitarisei ruzivo kubva pachiteshi:

PS takaona glitch isinganzwisisike - kana mudziyo wakabatana kuburikidza nekuchinja kwakadaro, uyezve wakabairwa pane inogadziriswa switch, HAZVICHAshanda kusvika tatangisa (!) switch. Ini handisati ndawana dzimwe nzira. kugadzirisa dambudziko iri.

Imwe pfungwa ine hukama neDHCP (kana ip dhcp snooping ikashandiswa) - pasina sarudzo dzakadaro:

ip dhcp snooping vlan 1-100
no ip dhcp snooping information option

Nokuda kwechimwe chikonzero handigoni kuwana IP kero zvakarurama ... kunyange izvi zvingava chikamu cheDHCP server yedu

Uye Mac OS & Linux (iyo ine yekuzvarwa 802.1x tsigiro) edza kutsigira mushandisi, kunyangwe kana chokwadi neMac kero yakagadziriswa.

Muchikamu chinotevera chechinyorwa, tichatarisa kushandiswa kwe802.1x yeWireless (zvichienderana neboka iro account yemushandisi ndeyayo, isu "tichaikanda" mumambure anoenderana (vlan), kunyangwe ivo vachabatana zvakafanana SSID).
