Span, rspan, na erpan ni tekinike ikoreshwa mumiyoboro yo gufata no gukurikirana ibyambu byo gusesengura. Dore incamake ya buri:
SPAP (Isesengura ryanditse rya Port)
Intego: Byakoreshejwe Kuri Indorerwamo Kumurongo Wihariye cyangwa Vlans kumurongo ugana ku kindi cyambu cyo gukurikirana.
Koresha urubanza: Nibyiza gusesengura traffic yimodoka kumurongo umwe. Imodoka ni indorerwamo ku cyambu cyagenwe aho umusenguzi wumuyoboro ushobora kuyifata.
Rspan (Ikibanza cya kure)
Intego: Kugura ubushobozi bukoreshwa muburyo bwinshi kumurongo.
Koresha Urubanza: Emerera gukurikirana traffic kuva kumurongo umwe ujya kurundi ruhande. Nibyiza kubintu aho igikoresho cyo gukurikirana giherereye muburyo butandukanye.
Erpan (ikibanza cya kabiri cya kabiri)
Intego: Ihuza RSpan hamwe na GRE (generic roulat ya moshi) kugirango ushyire hejuru yimodoka indorerwamo.
Koresha Urubanza: yemerera gukurikirana umuhanda hejuru yimiyoboro yatsinze. Ibi ni ingirakamaro mubwubatsi bugoye aho ibinyabiziga bigomba gufatwa kubice bitandukanye.
Hindura isesengura ryanditse (umwanya) ni uburyo bunoze, bugenzura imihanda minini. Iyobora cyangwa indorerwamo traffic kuva ku cyambu cyangwa VLAN ku cyambu. Ibi rimwe na rimwe bita isomo. Ikibanza gikoreshwa mugukemura ibibazo byo guhuza no kubara imikoreshereze yimiyoboro n'imikorere, mubandi benshi. Hariho ubwoko butatu bwibitanwa bishyigikiwe nibicuruzwa bya Cisco ...
a. Umwanya cyangwa umwanya waho.
b. Ikibanza cya kure (RSPAN).
c. Yaka umuriro wa kabiri (Ersan).
Kumenya: "Guhuza ™ umuhigi wa packet hamwe na spoker, rspan nibiranga erpan"
Umwanya / Indorerwamo yumuhanda / Indorerwamo y'ibirori ikoreshwa mubikorwa byinshi, hepfo irimo bimwe.
- gushyira mubikorwa indangamuntu / ips muburyo bwabasambanyi.
- Guhamagara Guhamagara Kubona Ibisubizo.
- Kubahiriza umutekano impamvu zo gukurikirana no gusesengura traffic.
- Gukemura ibibazo byo guhuza, gukurikirana ibinyabiziga.
Utitaye kubwoko bwubusonde bukora, inkomoko yubusomo bushobora kuba ubwoko ubwo aribwo bwose bwa PRM ya Port
Ubusonga bushyigikira gukurikirana imihanda ishingiye (ingress umwanya), traffic traffic (ewast, cyangwa traffic traffic mubyerekezo byombi.
- Inshinge ya inshinge (RX) traffic traffic yakiriwe nibyambu bya Inkomoko na Vlans ku cyambu. Kugereranya Gukoporora Ibinyabiziga mbere yo guhindura (kurugero mbere yikiruhuko cyangwa acl filteri, QoS cyangwa Shingress cyangwa Polisi ya Estress).
. Kuyungurura cyangwa guhindura hamwe na vacl cyangwa acl filteri, QoS cyangwa ibikorwa byashizweho cyangwa ibikorwa bya polisi byafashwe mbere yo guhinduranya ibyambu byo kurimbuka.
- Iyo ijambo ryibanze ryakoreshejwe, ryapa gufata urumogato rwakiriwe kandi rwoherezwa nibyambu byinkombe na Vlans ku cyambu.
- Umwanda / RSPAN mubisanzwe yirengagije CDP, STP BPDU, VTP, DTP na Pagp amakadiri. Nyamara ubwo bwoko bwumuhanda bushobora koherezwa mugihe itegeko ryo kwishyurwa ryashyizweho.
Umwanya cyangwa umwanya waho
Kugereranya Indorerwamo kuva kumurongo umwe cyangwa myinshi kuri switch kumurongo umwe cyangwa byinshi kumurongo umwe; Noneho ugereranywa ahanini uvugwa mugihe cyaho.
Umurongo ngenderwaho cyangwa ibibujijwe kumwanya waho:
- Igice cya 2 cyanditseho icyambu cya 3 kirashobora gushyirwaho nkisoko cyangwa ibyambu byerekanwe.
- Inkomoko irashobora kuba ibyambu bimwe cyangwa byinshi cyangwa VLAN, ariko ntabwo bivanze.
- Ibyambu byibimenyetso byemewe byimbuga bivanze nibyambu bidahurika.
- Kugera kuri 64 ibyambu byerekanwe birashobora gushyirwaho kumurongo.
- Iyo tugenera icyambu cyerekezo, iboneza ryumwimerere ntirinze. Niba iboneza ryakuweho, iboneza ryumwimerere kuri kiriya cyambu.
- Iyo shiraho icyambu cyerekezo, icyambu cyakuwe muri Bundle ya Ethenchanl iyo ari imwe murimwe. Niba ari icyambu cyaciwe, icyerekezo cyerekezo kibafitiye iboneza ryanditse.
- Ibyambu byerekanwe ntabwo bishyigikira umutekano w'icyambu, 802.1x Kwemeza, cyangwa Vlans Yigenga.
- Icyambu kirashobora gukora nk'icyambu cyerekezo kimwe gusa.
- Icyambu ntigishobora gushyirwaho nkicyambu kibi niba ari icyambu cyimodoka yikigereranyo cyangwa igice cyinkomoko VLAN.
- Imiyoboro ya Port (Ethenchan) irashobora gushyirwaho nkibyambu byinkomoko ariko ntabwo ari icyambu cyitabitse.
- Icyerekezo cyumuhanda ni "byombi" muburyo busanzwe.
- Ibyambu biteye aho ntibyitabira urugero rwa sport. Ntushobora gushyigikira DTP, CDP nibindi byaho birimo BPDUS mumodoka ikurikiranye, kuburyo BPDus iyariyo yose igaragara ku cyambu igana yandukuwe ku cyambu cya Inkomoko. Ntabwo rero uhuza na switch kuri ubu bwoko bwibintu bishobora gutera umuyoboro. Ibikoresho bya AI bizamura imikorere yakazi, kandikutagaragara aiSerivisi irashobora kuzamura ireme ryibikoresho bya AI.
- Iyo VLAN yashyizweho nkisoko (ahanini ivugwa muri Vsin) hamwe na hamwe na endress ifiti yagenwe, imbere ya paki yisumbuye gusa niba paki zizimye muri VLAN imwe. Kopi imwe ya paki ivuye mumodoka ireba ku cyambu rusange, hanyuma izindi kopi ya paki ivuye mu modoka enye.
- VSPAN ikurikirana traffic traffic gusa cyangwa yinjira murwego rwa 2 muri VLAN.
Ikibanza cya kure (RSPAN)
Ikibanza cya kure (RSPAN) isa nigihe cyamamaye, ariko ishyigikira ibyambu byinkomoko, inkomoko yakurikiranye kuri spitch ya enterineti ikwirakwizwa hejuru yimyenda myinshi kandi yemerera aho ujya ibikoresho. Buri cyiciro RSPAN itwara ibinyabiziga hejuru yumukoresha wihariye bwa rlan Vlan muri bose bitabiriye. Iyi Vlan iraturuka ku zindi ndwara, yemerera RSPAN Imodoka Imodoka igomba gutwarwa hirya no hino kandi igashyikirizwa aho yerekeza. RSPAN igizwe nisomo rya RSPAN, RSPAN VLAN, na RSPAN igana.
Amabwiriza cyangwa Kubuza RSPAN:
- VLAN Yihariye igomba gushyirwaho kugirango igere aho ujya izanyura hejuru ya spitche ya hagati ukoresheje Trunk ihuza icyambu cyerekezo.
- irashobora gukora ubwoko bumwe - byibuze icyambu kimwe cyangwa byibuze VLAN imwe ariko ntishobora kuba ivanze.
- Aho ujya ni rspan vlan aho kuba icyambu kimwe muri switch, niko ibyambu byose muri rspan vlan bizahabwa urujya n'uruza.
- Kugena Vlan iyo ari yo yose ya RSPAN mugihe cyose ibikoresho byose byitabira ibikoresho bya RSPAN Vlans, hanyuma ukoreshe Skuran Vlan kuri buri cyiciro cya RSPAN
- VTP irashobora gutangaza iboneza rya 1 kugeza 1024 nkuko rlans ya rsan, igomba kugena amakuru arenga 1024 nkuko rlans ya rspan kubikoresho byose, hagati, hamwe nibikoresho bya leta.
- Kwiga Aderesi ya Mac birahagarikwa muri RSPAN VLAN.
Gushyira ahagaragara kure (Ersan)
Ikibanza cya kabiri cyaka (Ersan) kizana inzira rusange yo kuzunguruka (GRE) kubantu bose bafashwe kandi biyemerera koherezwa hejuru yikibuga cya 3.
Erpan ni aCisco NyiricyubahiroIkiranga kandi kirahari gusa kuri catalyst 6500, 7600, Nexus, na ASR 1000 kuramburwa kugeza ubu. ASR 1000 ishyigikira isoko ya erspan (gukurikirana) gusa kuri Ethernet gusa, Gigabit Ethernet, hamwe na Port-Umuyoboro.
Umurongo ngenderwaho cyangwa ibibujijwe kuri erspan:
. Buri cyiciro cya Erspan isoko kirashobora kugira ibyambu cyangwa imitwe nkamasoko, ariko ntabwo byombi.
- Tutitaye ku bunini bwa Mtu, Ersan ikora layer 3 Paki zishobora kuba igihe kingana na 9202 bytes. Imodoka ya Erpan irashobora kugabanywa nimikorere iyo ari yo yose murusobe rwubahiriza ingano ya Mtu ntoya irenga 9,202.
- Ersan ntabwo ishyigikira agace k'ipaki. "Ntugahuze" biti yashyizweho umutwe wa iP ya paki ya erpan. Amasomo ya Erpan adashobora gutontoma ibipaki bya Erspan.
- Indangamuntu ya Ersan itandukanya ibinyabiziga bya Erpan bigera kuri IP imwe ya Aderesi ya Aderesi ya Ersan zitandukanye; Kugena indangamuntu ya Erspan igomba guhuza ninkomoko nibikoresho.
- Ku cyambu cy'inkomoko cyangwa isoko VLAN, Ersan irashobora gukurikirana inshigi, egress, cyangwa byombi. Mburabuzi, Ersan ikurikirana traffic zose, barimo amabara menshi kandi yikiraro (BPDE (BPDE).
.
- Ihitamo Vlan Vlan ntabwo rikora mu nama yakurikirana ya erspan ku murongo wa Wan.
- Erpan kuri Cisco ASR 1000 urukurikirane rushyigikira urwego 3 gusa. Imigaragarire ya Ethernet ntabwo ishyigikiwe kuri erspan iyo imaze gushyirwaho nka laprife 2.
- Iyo hashyizweho isomo binyuze muburyo bwa Ersan CLI, Isomo ryamasomo hamwe nubwoko bwibanze ntigishobora guhinduka. Kugirango uhindure, ugomba kubanza gukoresha ntaburyo bwiboneza kugirango ukureho isomo hanyuma ugahindura isomo.
- Cisco ios xe kurekura 3.4s: - Gukurikirana ibipaki byo muri Tunnese ingwa na IPN6 na IPV6 hejuru ya IP Trunnel Interface gusa kubisobanuro bya Erspan isoko.
- Cisco iOS Xe Gusohora 3.5s, inkunga yongeyeho ubwoko bwa Wan Imigaragarire ya BAN Isomo: Igice kinini (OC3, T3 / E3, Umwanya Wibanze
Ukoresheje Erpan nk'aho hakunze:
Kugirango ukoreshe erpan kugirango ukurikirane traffic ukoresheje ibyambu bimwe cyangwa byinshi mubikoresho bimwe, tugomba gukora isoko ya erspan hamwe na ersan aho tuba mubikoresho bimwe, biba bike bibera muri router, bisa nkibisanzwe.
Ibintu bikurikira birakurikizwa mugihe ukoresheje erpan nkumwanya waho:
- Amasomo yombi afite indangamuntu imwe.
- Amasomo yombi afite aderesi imwe. Iyi aderesi ya IP ni router ifite aderesi ya IP; Nibyo, aderesi ya IP cyangwa aderesi ya IP yashyizweho ku cyambu icyo ari cyo cyose.
