Span, Rspan, ndi Erpan ndi njira zomwe zimagwiritsidwa ntchito popanga ma networking kuti zigwire ndikuwunika magalimoto kuti ayang'anire. Nayi chidule chachidule chilichonse:
Span (adasinthira part)
Cholinga: Amagwiritsidwa ntchito poyendetsa magalimoto pamadoko kapena ma vlans posinthira ku doko lina kuti awunikire.
Kugwiritsa Ntchito Mlandu: Choyenera pakuwunika kwa magalimoto wamba pa switch imodzi. Magalimoto amalowerera padoko lomwe linasankhidwa pomwe percer lytzer imatha kugwira.
Rspan (Spote Span)
CHOLINGA: Kukula kwa cartary kudutsa mawiti ambiri mu netiweki.
Kugwiritsa Ntchito Mlandu: Kulola kuwunika kwa magalimoto kuchokera ku switch imodzi kupita kwina kolumikizana. Zothandiza pazochitika zomwe chipangizo chowunikira chili pa switch.
Erpan (oyang'anira kutali kwambiri)
Cholinga: Kuphatikiza rspan ndi gre (generic extraphy yozungulira) kuti isinthe magalimoto owoneka bwino.
Kugwiritsa Ntchito: kumalola kuwunika kwa magalimoto pamaneti. Izi ndizothandiza mu zomanga zovuta pa intaneti zomwe magalimoto amafunikira kugwidwa pamagulu osiyanasiyana.
Sinthani Port Seler (SPAN) ndi bwino, yowunikira magalimoto oyendayenda. Imawongolera kapena kugawidwa magalimoto kuchokera ku doko kapena vran ku doko komwe akupita. Izi nthawi zina zimatchedwa gawo la gawo. Span imagwiritsidwa ntchito polumikizana ndi zovuta zolumikizirana ndikugwiritsa ntchito magwiridwe antchito ndi ntchito, pakati pa ena ambiri. Pali mitundu itatu ya mabens omwe amathandizidwa pazinthu za Cisco ...
a. Span kapena kanthawi.
b. Span yakutali (Rspan).
c. Okhazikika kutali kwambiri (Erpan).
Kudziwa: "MyLraning ™ Network Broker Broker ndi Span, RSPAN ndi Erpan"
Katswiri wa Span / Communing / Port Specing amagwiritsidwa ntchito pazolinga zambiri, pansipa zimaphatikizapo zina.
- kukhazikitsa ma ID / IPS munjira zachiwerewere.
- Kujambulitsa kwa Voip.
- Zifukwa zotetezera zowunikira ndikuwunika magalimoto.
- Zovuta Zovuta Zovuta, kuwunika magalimoto.
Mosasamala kanthu za mtundu wa chivumba, masikono amatha kukhala mtundu wina wa doko, kusintha kwadoko, kadokotala wokhazikika (kadongosolo)
Magawo a Span amathandizira kuwunika kwa ingress Syff Refere (Ingess Span), Magalimoto a Sporty (a Esirse), kapena magalimoto mbali zonse ziwiri.
- Interress Span (RX) Magalimoto olandiridwa ndi madontho ndi Vlans kupita ku port. Kupaka kwa mabatani musanasinthe (mwachitsanzo musanasinthe chilichonse kapena Flue Squase, QOS kapena kumiza kapena kuponyera poponya).
- Mapulogalamu a TX Zosintha zonse zovomerezeka kapena kusinthana ndi yina ya yina ya acl kapena ma acl kapena ipress kapena kunyengerera zojambulazo zisanachitike kusintha kwapa.
- Pamene mawu ofunikira omwe amagwiritsidwa ntchito, ma cun amajambula magalimoto apaintaneti omwe amalandila ndikufalikira ndi madokotala ndi ma vlans kupita ku port.
- Span / Rspan nthawi zambiri imanyalanyaza cdp, stp bpdu, vtp, dtp ndi mafelemu. Komabe mitundu yamagalimoto iyi imatha kutumizidwa ngati malo obwezeretsanso omwe amakonzedwa.
Span kapena kanthawi
Span magalasi amagalimoto kuchokera kumodzi kapena zingapo mawonekedwe a switch pa imodzi kapena zingapo kusinthira; Chifukwa chake mpake umatchedwa nthawi yakomweko.
Malangizo kapena zoletsa ku Span:
- Onse osanjikiza 2 madokotala ndi osanjikiza 3 madoko amatha kukhazikitsidwa ngati gwero kapena madoko opita.
- Gwero likhoza kukhala madoko amodzi kapena angapo, koma osati kusakanikirana kwa izi.
- Thupi madoko ndi ma 5
- mpaka 64 madoko opita ku Span omwe akupita akhoza kukonzedwa pa switch.
- Tikakhazikitsa doko lopita, kasinthidwe koyambirira kumasindikizidwa. Ngati makonzedwe a kasupe amachotsedwa, kukhazikika koyambirira padoko lidzabwezeretsedwa.
- Mukakhazikitsa doko lopita, doko limachotsedwa pamtengo uliwonse wa embinnch ngati inali imodzi. Zikadakhala kuti anali doko loponya, kasupe komwe amapita kukakonzanso popita.
- Madoko omwe akupita sagwirizana ndi Port Security, 802.1X kutsimikizika, kapena Vula Yachinsinsi.
- Doko amatha kukhala ngati doko limodzi lolowera gawo limodzi lokha.
- Doko silingapangidwe ngati doko lopita ngati gawo la gawo la gawo la span kapena gawo lina la vlan.
- Port Channel Anterofals (etherthnnel) imatha kukhazikitsidwa ngati madoko koma osati popita komwe mukupita.
- Kuwongolera magalimoto ndi "onse" mosasintha kwa magwero a SPAN.
- Madoko omwe akupita satenga nawo mbali munthawi ya Spain. Simungathandizire DTP, CDP ETC. Katswiri wam'deralo akuphatikiza BPDUS pamsewu, kotero bpdus iliyonse yomwe idawoneka padoko lomwe likupita limakopera padoko. Chifukwa chake salumikiza kusinthanitsa ndi mtundu uwu wa nthawi yomwe imapangitsa kuti pakhale chiuno. Zida za AI zidzakulitsa ntchito yogwira ntchito, ndipoosadziwika aiNtchito imatha kukonza zida za AI.
- Pamene Vlan idakonzedwa ngati ma span gwero (makamaka limatchedwa vspan) yokhala ndi ma tress ndi zolakwika zomwe zidakonzedwa, zomwe zimasungidwa ndi ma picket omwewo. Kope limodzi la paketi likuchokera ku Ingress Surft pa doko la ingress, ndipo panduna ina ya paketiyo ikuchokera ku magalimoto opunthwa pa doko la alonda.
- Oyang'anira vspan amangoyendetsa galimoto yomwe imachoka kapena kuphatikizira madoko 2 ku Vlan.
Kutali Span (RSPAN)
Kutali kakhyero (Rspan) ndikofanana ndi span, koma imathandizira madoko, ndipo popita kumadoko opita kumayendedwe osiyanasiyana amagawa masinthidwe angapo ndikupereka zida zojambulira za pa intaneti. Gawo lililonse la Rspan limakhala ndi kuchuluka kwa ma span ku RSPAN VLLe ku Switch onse. Vlan iyi imakhala yosinthira kwina, kulola magalimoto a Rspan kuti anyamuke ma switches angapo ndikupereka malo otawola omwe akulanda. Rspan imakhala ndi gawo la Rspan Grance, lomwe vspan vlan, ndi gawo la RSPAN.
Malangizo kapena zoletsa ku Rspan:
- Vlan inayake iyenera kukonzedwa kuti ikhale komwe ikuyenda kudutsa pakati pa thunthu la mpweya kudzera padoko komwe mukupita.
- Itha kupanga mtundu womwewo - doko limodzi kapena vran imodzi koma siyingakhale yosakanikirana.
- Kupita komwe gawoli ndi RSPAN VLL Ken osati doko limodzi pazenera, kotero madoko onse ku Rspan vran amalandila magalimoto oyenda.
- Sinthani vlan iliyonse vspan van bola ngati njira zonse zogwirizira
- VTP imatha kufalitsa kusinthika kwa VLENE 1 mpaka 1024 monga Vulan Vlans, iyenera kupanga ma vlans okwanira 1024 monga ma vlans onse a network.
- Kuphunzira adilesi ya MAC kuli wolumala mu rspan vlan.
Adasunganso Span Retan (Erpan)
Scan yopepuka yofalikira (Erpan) imabweretsa zolemba zozungulira (GRE) pazomwe zidawagwira ndikulola kuti zitheke mbali 3.
Erpan ndi aCisco Reporrientarymawonekedwe ndipo akupezeka kokha kuthandizira kwa 6500, 7600, Nexus, ndi Asr 1000 papulatifomu. ASR 1000 imathandizira Erpan Great (kuwunikira) kokha ku Ethernet, Gigabit Ethernet, ndi masinthidwe a Port-Chap.
Malangizo kapena zoletsa kwa Erpan:
- Magawo a Erpan a Norpan samakopera Erpan Grepan Great Magalimoto ochokera kumayiko. Gawo lililonse la erpan limatha kukhala ndi madoko kapena ma vlans ngati magwero, koma osati onse awiri.
- Mosasamala kanthu za kukula kwa MTU Magalimoto a Erpan atha kugwera ndi mawonekedwe aliwonse mu netiweki yomwe imapangitsa MTU kukula kocheperako kuposa ma byte 9,202.
- Erpan sathandizira kugawanika kwa paketi. "Osatinso chidutswa" pang'ono amakhazikitsidwa mu mutu wa IP ya mapaketi a Erpan. Magawo a Erpan omwe akupita sangakonzenso mapaketi a Erpan.
- ID ya Erpan imasiyanitsa magalimoto a Erpan kufika komweko. ID ya Erpan Id iyenera kufanana ndi magwero ndi komwe akupita.
- Padoko kapena gwero la val, Erpan amatha kuwunikira ingress, zoyipa, kapena kuphatikizika ndi magalimoto onse. Mosakhazikika, a Erpan amayang'anira magalimoto onse, kuphatikizapo ma metricist ndi Bridtocol Data.
- Makina a Trannel amathandizidwa monga momwe gawo la Erpan limayendera, IPinip, SVTI, SPV6
- Kusankha kwa val vran sikogwira ntchito mu gawo lowunikira za Erpan pa Win kuphatikizira.
- Erpan pa Cisco Asr 1000 Plass Routers amathandizira kusanjikiza kokha 3 mawonekedwe. Mawonekedwe a Ethernet sathandizidwa pa erpan atakonzedwa ngati malo ophatikizira 2.
- Gawo likakonzedwa kudzera mu erpan cli, ID ya gawo ndi mtundu wa gawo silingasinthidwe. Kuti muwasinthe, muyenera kugwiritsa ntchito mtundu wa lamulo la kusinthika kuti muchotse gawo kenako ndikukonzanso gawoli.
- Cisco IOS XE:
- Cisco IOS XE, thandizo lidawonjezedwa ndi mitundu yotsatirayi monga gwero la magwero: serilil, mawu, ndi mawu osakira adawonjezeredwa kumodzi.
Kugwiritsa ntchito Erpan ngati nthawi yakomweko:
Kuti mugwiritse ntchito erpan kuti muwunikire madoko kapena zingapo kapena vlans mu chipangizo chomwecho, tiyenera kukhala ndi gawo loyambira ku Erpan ndi Erpan momwemo, kutuluka kwa deta kumachitika mkati mwa rauta.
Zinthu zotsatirazi ndizogwira ntchito pogwiritsa ntchito erpan ngati nthawi yakomweko:
- Magawo onse ali ndi ID yomweyo.
- Magawo onse ali ndi adilesi yomweyo ya IP. Adilesi iyi ya IP ndi router yanu ya ip; Ndiye kuti, adilesi ya IP kapena adilesi ya IP idakonzedwa padoko lililonse.
