ACL Nhanganyaya

Access Control Lists (ACLs) rondedzero yemirairo inoshandiswa kunerouterinterfaces. Aya magwaro ekuraira anoshandiswa kutaurirarouterndeapi mapaketi anogona kugamuchirwa uye ndeapi mapaketi anoda kurambwa. Kana iri yekuti pakiti inotambirwa here kana kurambwa, inogona kutariswa nemamiriro chaiwo anoratidza senge kwabva kero, kero yekuenda, nhamba yechiteshi, nezvimwe.
ACL basa:
1) Deredza network traffic uye uvandudze mashandiro etiweki. Semuyenzaniso, ACL anogona kutsanangura kuti mhando iyi data packet ane yepamusoro pokutanga kwakavakirwa protocol ayo, uye anogona pre kugadzirwa nemambure mano mumamiriro akafanana.
2) Ipa matanho ekudzora ekuyerera kwekutaurirana.
3) Ipa matanho ekuchengetedza ekutanga ekuwana network.
4) Pane network network interface, tarisa kuti ndeupi rudzi rwekutaurirana traffic inotumirwa uye ndeupi rudzi rwekutaurirana traffic yakavharwa.
Iko kushandiswa kwekambani yedu yakazvigadzira hdv eponoltACL:
1. Gadzira ane ACL (kusanganisira Basic, Advanced, uye Link), pamwe inokosha ACLs kubva 2000 kusvika 2999, yepamusoro ACLs kubva 3000 kusvika 4999, uye batanidza ACLs kubva 5000 kusvika 5999. Somuenzaniso, ACL 2000 (Basic ACL) .
2. Configure mitemo muna ACL 2000 (kusvika 16 mitemo inogona configured per ACL), somuenzaniso: mutemo 1 kuramba tsime chero
Zvinorehwa nemurairo uyu kugadzira mutemo une id 1 uye kurasa mapaketi ese anouya.
3. Kuiswa, ndiko kuti, kushandiswa, zvakadai se: packet filter inbound 2000 mutemo id 1 port ge 1
Uyu murairo unoda kubuda muACL 2000 interface uye kuigadzirisa mumutauro wepasi rose, zvinoreva kuisa Rule 1 inoenderana mu ACL 2000 paGE1 port yeOLT. Panguva ino, mapaketi ese anopinda GE1 chiteshi cheOLTzvicharaswa.
Zviri pamusoro apa ipfupi pfupiso yeACL yekuraira runyorwa software tekinoroji, inogona kushandiswa sereferensi kune wese munhu. Kambani yedu ine yakasimba software uye hardware tekinoroji timu, iyo inogona kupa nyanzvi tekinoroji masevhisi kune vatengi. Zvigadzirwa zvedu zvinotengeswa zvakanyanya zvinofukidza mhando dzakasiyana dzeONUakatevedzana zvigadzirwa, kusanganisira ACONU/kutauriranaONU/akangwaraONU/bhokisiONU, etc. Zviri pamusoro apaONUseries zvigadzirwa zvinogona kushandiswa kunetiweki zvinodiwa mumamiriro akasiyana siyana.
