CISCO NX-OS Yepamberi Network Operating System Yakagadzirwa

Zvigadzirwa Zvinotsanangurwa

• Time Synchronization Protocol: NTP (Network Time Protocol)
• Support: Cisco NX-OS
• Features: NTP nguva server kumisikidzwa, NTP vezera hukama, kuchengetedza maficha, virtualization rutsigiro

Mirayiridzo Yekushandiswa Kwechigadzirwa

Kugadzirisa NTP yeKuyananisa Nguva
Usati wabatanidza mudziyo wako wetiweki nemaseva eNTP, funga zvinotevera zvinongedzo:

1. NTP inofananidza nguva yakataurwa nemidziyo yakasiyana-siyana uye inodzivirira kuwiriranisa neyakasiyana zvakanyanya nguva masosi.
2. Kana usingakwanise kubatanidza kune stratum 1 server, shandisa veruzhinji NTP maseva anowanikwa painternet kuti ayananise.
3. Kana kuwanikwa kweinternet kuchirambidzwa, gadzirisa zvigadziriso zvenguva yemuno sekunge zvakawiriraniswa kuburikidza neNTP.

Kugadzira NTP Peer Relationships
Kusarudza mauto-anoshumira nguva yekuwiriranisa uye kuve nechokwadi chenguva chaiyo kana server yakundikana:

• Gadzira hukama hwevezera hweNTP nevatambi vaunoda.
• Shandisa rondedzero-yakavakirwa zvirambidzo kana encrypted echokwadi nzira dzekuwedzera chengetedzo.

Kugovera NTP Configuration Uchishandisa CFS
Cisco Fabric Services (CFS) inobvumira kugovera magadzirirwo emunharaunda eNTP panetiweki. Tevera matanho aya:

1. Gonesa CFS pamudziyo wako kuti utange network-wide lock paNTP kumisikidza.
2. Mushure mekuchinja kwegadziriro, zvirase kana kuti zvipire kusunungura kiyi yeCFS.

Kuwanikwa Kwepamusoro uye Virtualization Tsigiro
Ita shuwa kuwanikwa kwepamusoro uye kutsigirwa kwe virtualization kweNTP ne:

• Kugadzirisa NTP vezera redundancy kana server yakundikana.
• Kuziva chaiyo yekufambisa uye kutumira (VRF) zviitiko zveNTP kushanda.

FAQ

• Zvinodiwa uye Nhungamiro Yekugadzirisa NTP
  • Zvinodiwa: Ita shuwa yekubatanidza network uye kuwana kune inodiwa NTP maseva.
  • Nhungamiro: Shandisa maficha ekuchengetedza senge manyorerwo uye echokwadi yekuyananisa nguva yakachengeteka.

Ruzivo NezveNTP

• Iyo Network Time Protocol (NTP) inowiriranisa nguva yezuva pakati peseti yemaseva enguva yakagoverwa uye vatengi kuitira kuti iwe ugone kuwiriranisa zviitiko kana iwe uchigamuchira matanda ehurongwa uye zvimwe zviitiko zvakanangana nenguva kubva kune akawanda network zvishandiso. NTP inoshandisa Mushandisi Datagram Protocol (UDP) seprotocol yayo yekufambisa. Yese NTP yekutaurirana inoshandisa Coordinated Universal Time (UTC).
• Sevha yeNTP inowanzogashira nguva yayo kubva kune inotenderwa nguva sosi, sewachi yeredhiyo kana wachi yeatomu yakasungirirwa pane sevha yenguva, yobva yagovera nguva ino panetiweki. NTP inoshanda zvakanyanya; hapana inopfuura pakiti imwe paminiti inodiwa kuwiriranisa michina miviri mukati me millisecond yeumwe neumwe.
• NTP inoshandisa stratum kutsanangura chinhambwe pakati petiweki mudziyo uye ine mvumo nguva sosi:
  • Iyo stratum 1 nguva sevha yakanamirwa zvakananga kune inotenderwa nguva sosi (senge redhiyo kana atomic wachi kana GPS nguva sosi).
  • Iyo stratum 2 NTP server inogamuchira nguva yayo kuburikidza neNTP kubva kune stratum 1 nguva sevha.
• Isati yawiriranisa, NTP inofananidza nguva yakashumwa nemidziyo yakawanda yetiweki uye haiwirirani neimwe yakasiyana zvakanyanya, kunyangwe iri stratum 1. Nekuti Cisco NX-OS haigone kubatana neredhiyo kana atomic wachi uye kuita senge stratum 1. Sevha, tinokurudzira kuti ushandise maseva eruzhinji eNTP anowanikwa paInternet. Kana network yakaparadzaniswa neInternet, Cisco NX-OS inokutendera kuti ugadzirise nguva sekunge yakawiriraniswa kuburikidza neNTP, kunyangwe yanga isiri.
  Cherechedza
  Iwe unogona kugadzira hukama hweNTP nevezera kuti usarudze iyo-inoshumira nguva iyo yaunoda kuti network yako kifaa ifunge kuwiriranisa uye kuchengetedza nguva chaiyo kana server yakundikana.
• Nguva inochengetwa pachigadzirwa chinhu chakakosha, saka isu tinokurudzira zvakasimba kuti iwe ushandise chengetedzo maficha eNTP kudzivirira netsaona kana kwakashata marongero enguva isiriyo. Nzira mbiri dziripo: yekuwana rondedzero-yakavakirwa kudzora chirongwa uye yakavharidzirwa yechokwadi meshini.

NTP sevha yenguva

Mimwe michina inogona kuimisa sevhavha yenguva. Iwe unogona zvakare kugadzirisa chishandiso kuti chiite seane chiremera cheNTP server, ichichigonesa kugovera nguva kunyangwe isina kuwiriraniswa kune yekunze nguva sosi.

Kugovera NTP Kushandisa CFS

• Cisco Fabric Services (CFS) inogovera iyo yemuno NTP kumisikidzwa kune ese maCisco madivayiri munetiweki.
• Mushure mekugonesa CFS pamudziyo wako, network-wide lock inoiswa kuNTP pese panotangwa gadziriro yeNTP. Mushure mekuita shanduko yeNTP, unogona kuirasa kana kuita.
• Chero zvazvingava, kiyi yeCFS inobva yasunungurwa kubva pakushandisa kweNTP.

Maneja wewachi

• Mawachi zviwanikwa zvinoda kugovaniswa mukati memaitiro akasiyana.
• Multiple time synchronization protocols, senge NTP uye Precision Time Protocol (PTP), inogona kunge ichimhanya muhurongwa.

Kuwanikwa Kwepamusoro

• Stateless restarts inotsigirwa yeNTP. Mushure mekutangazve kana mutariri switchover, iyo inomhanya gadziriso inoshandiswa.
• Unogona kugadzirisa NTP vezera kuti vape redundancy kana sevha yeNTP ikatadza.

Virtualization Tsigiro

NTP inocherekedza chaiyo yekufambisa uye kutumira (VRF) zviitiko. NTP inoshandisa iyo default VRF kana ukasagadzirisa chaiyo VRF yeNTP server uye NTP peer.

Zvinodiwa zveNTP

NTP ine zvinotevera zvinodikanwa:
Kugadzirisa NTP, unofanirwa kuve nekubatana kune imwechete sevha iri kuita NTP.

Nhungamiro uye Miganhu yeNTP

NTP ine zvinotevera zvigadziriso nhungamiro uye zvinogumira:

• Iyo show ntp chikamu chimiro CLI kuraira hairatidze yekupedzisira chiitiko nguva stamp, chiitiko chekupedzisira, chiitiko chekupedzisira, uye chikonzero chekutadza kwekupedzisira.
• NTP server mashandiro anotsigirwa.

Kana iwe uine maseva maviri, unogona kugadzirisa akati wandei kuti anongedze kune imwe sevha uye yakasara michina inongedza kune imwe sevha. Iwe unogona ipapo kugadzirisa kushamwaridzana kwevezera pakati pemasevha maviri aya kuti ugadzire yakavimbika NTP kumisikidzwa.
• Kana iwe uine sevha imwe chete, iwe unofanirwa kugadzirisa ese maturusi sevatengi kune iyo server.
• Iwe unogona kugadzirisa kusvika ku64 NTP masangano (maseva uye vezera).
• Kana CFS yakadzimwa kuNTP, NTP haigoveri chero zvigadziriso uye haigamuchire kugoverwa kubva kune mamwe madivayiri munetiweki.
• Mushure mekunge kugoverwa kweCFS kwagoneswa kuNTP, kupinda kweNTP configuration command inokiya network yeNTP kumisikidza kusvika murairo wekuita wapinda. Munguva yekukiyiwa, hapana shanduko inogona kuitwa kune iyo NTP kumisikidzwa nechero imwe mudziyo munetiweki kunze kwemudziyo watanga kukiya.
• Kana ukashandisa CFS kugovera NTP, zvishandiso zvese zviri munetwork zvinofanirwa kunge zvine maVRF akafanana akarongwa sezvaunoshandisa paNTP.
• Kana iwe ukagadzirisa NTP muVRF, ita shuwa kuti sevha yeNTP nevezera vanogona kusvika kune mumwe nemumwe kuburikidza nemaVRF akagadziriswa.
• Iwe unofanirwa kugovera nemaoko makiyi eNTP echokwadi paNTP server uye Cisco NX-OS zvishandiso panetiweki.
• Kana iwe uri kushandisa chinja semudziyo wekumucheto uye uchida kushandisa NTP, Cisco inokurudzira kushandisa iyo ntp yekuwana-boka rekuraira uye kusefa NTP chete kune inodiwa kumucheto zvishandiso.
• Kana iyo sisitimu yakagadziridzwa ne ntp passive, ntp nhepfenyuro mutengi, kana ntp multicast mirairo yevatengi, kana NTP inogamuchira inouya symmetric inoshanda, kutepfenyura, kana multicast packet, inogona kuseta ephemeral peer association kuitira kuti iwirirane neanotumira. .

• Kana iyo ntp yechokwadi yekuraira yakatsanangurwa, kana symmetric inoshanda, kutepfenyura, kana multicast packet yagamuchirwa, sisitimu haiwirirani kune vezera kunze kwekunge packet inotakura imwe yemakiyi echokwadi anotsanangurwa mu ntp trusted-key global configuration command.
• Kuti udzivise kuwiriranisa neasina kutenderwa network mauto, iyo ntp inotendesa murairo inofanirwa kutsanangurwa chero nguva iyo ntp passive, ntp nhepfenyuro mutengi, kana ntp multicast mutengi murairo wataurwa kunze kwekunge mamwe matanho, senge ntp yekuwana-boka rekuraira, yatorwa kudzivirira mauto asina mvumo kubva pakutaurirana nesevhisi yeNTP pamudziyo.
• Iyo ntp inotendesa murairo haitendese kushamwaridzana kwevezera kwakagadziriswa kuburikidza ne ntp server uye ntp peer configuration mirairo. Kusimbisa iyo ntp server uye ntp peer kushamwaridzana, tsanangura kiyi kiyi.
• Shandisa NTP kutepfenyura kana masangano akawanda kana kurongeka kwenguva uye kuvimbika zvinodiwa zvine mwero, network yako iri munharaunda, uye network ine vanopfuura makumi maviri vatengi. Isu tinokurudzira kuti ushandise NTP kutepfenyura kana multicast kushamwaridzana mumatiweki ane mashoma bandwidth, system memory, kana CPU zviwanikwa.
