Function yog qhov qhia ncaj qha tshaj plaws

Rau kev nkag mus rau txheej txheej, yooj yim QoS lav, kev ruaj ntseg mechanisms, kev txhawb nqa rau cov tswv yim tswj kev sib koom tes, ncua kev cai ntoo thiab VLANs yog tag nrho cov haujlwm tseem ceeb, txawm li cas los xij, yog tias koj txheeb xyuas kom zoo, qee qhov haujlwm tuaj yeem muab faib ntxiv raws li qhov yooj yim pom, thiab cov subdivided. kev ua haujlwm yog qhov laj thawj tseem ceeb rau cov khoom sib txawv thiab ib txoj hauv kev tseem ceeb los cuam tshuam cov nqi ntxiv ntawm cov khoom. Txhawm rau muab cov neeg siv tau yooj yim dua hauv cov ntawv thov, QoS txoj cai ntawm kev hloov pauv yuav tsum txhawb nqa ntau qib pob ntawv qhov tseem ceeb, qhov tseem ceeb tuaj yeem raug teeb tsa rau MAC chaw nyob, VLAN, IP chaw nyob, thiab chaw nres nkoj feem. Nyob rau tib lub sijhawm, qhov hloov pauv yuav tsum muaj kev tswj xyuas kom zoo thiab muaj peev xwm txwv tsis pub ntws, txhawb nqa Diffserv cov kev pabcuam sib txawv, thiab txawj ntse paub qhov txawv ntawm daim ntawv thov ntws raws li qhov chaw / qhov chaw MAC / IP kom tau raws li cov kev xav tau ntawm cov ntawv thov multimedia real-time. Txawm hais tias qee qhov kev hloov pauv ntawm kev ua lag luam tam sim no thov kom muaj QoS lav, lawv tsuas yog txhawb nqa qhov tseem ceeb ntawm ib theem, uas ua rau muaj kev cuam tshuam ntau rau cov neeg siv cov kev siv tswv yim.

Kev them nyiaj yug VLAN

VLAN yog lub network virtual hauv cheeb tsam. Los ntawm kev faib cov cheeb tsam hauv cheeb tsam mus rau hauv lub network virtual VLAN network ntu, kev tswj hwm lub network thiab kev ruaj ntseg network tuaj yeem ua kom muaj zog, thiab cov ntaub ntawv tsis tsim nyog tshaj tawm tuaj yeem tswj tau, Pab pawg ua haujlwm hauv lub network tuaj yeem tawg los ntawm thaj chaw txwv hauv kev sib koom tes, thiab faib cov subnet raws li kev tswj hwm kev ua haujlwm, cov hloov pauv ntawm cov tuam txhab sib txawv muaj peev xwm txhawb nqa VLANs sib txawv, thiab tus naj npawb ntawm VLANs txhawb nqa kuj txawv. Kev tswj hwm kev ua haujlwm hauv lub network Los ntawm kev tswj hwm lub network, koj tuaj yeem siv software tswj kev tswj hwm thiab teeb tsa qhov hloov pauv, piv txwv li, nws tuaj yeem tswj hwm los ntawm Web browser, Telnet, SNMP, RMON, thiab lwm yam. Feem ntau, hloov chaw tsim khoom muab kev tswj hwm software lossis thib peb. -party tswj software rau remotely tswj tus hloov. Cov keyboards dav dav ua tau raws li SNMPMIBI / MIBII cov kev tswj xyuas kev ua haujlwm, thiab txhawb kev tswj hwm kev teeb tsa, kev tswj hwm kev pabcuam zoo, kev tswj lub tswb thiab lwm cov tswv yim, qhov nyuaj Gigabit hloov yuav txhawb RMON nquag saib xyuas los ntawm kev ntxiv ib pawg RMON built-in (mini-RMON).

Txuas kev sib sau

Kev sib txuas sib txuas tuaj yeem ua rau qhov sib txuas bandwidth ntawm cov keyboards thiab nruab nrab ntawm cov keyboards thiab servers muaj qhov ua tau zoo heev, piv txwv li, ob, peb, thiab plaub qhov sib txuas gigabit tuaj yeem khi ua ke los ua ob npaug ntawm qhov txuas bandwidth. Teeb tsa cov kev sib txuas tsis tu ncua hauv lub network, thiab siv Spanning Tree Protocol los thaiv qhov txuas txuas, uas yog qhov tsis muaj lub voj voog. Thaum ib qho tsis ua hauj lwm tshwm sim, qhov txuas thaub qab tau qhib.

Txhawb VRRP raws tu qauv

VRRP (Virtual Routing Redundancy Protocol) yog ib qho kev daws teeb meem los xyuas kom meej lub network kev ntseeg siab. Nyob rau hauv cov txheej txheem no, lub default gateway (DefaultGateway) ntawm lub davhlau ya nyob twg IP ntaus ntawv nyob rau hauv lub sib koom multi-access access nruab nrab yog redundantly thaub qab, yog li ntawd thaum ib tug ntawm peb-txheej hloov cov cuab yeej poob, lub backup ntaus ntawv yuav coj mus rau lub forwarding. ua hauj lwm nyob rau hauv lub sij hawm, Tus neeg siv muab pob tshab handover, uas txhim kho cov kev pab cuam network zoo. VRRP raws tu qauv zoo ib yam li Cisco's HSRP raws tu qauv, tab sis HSRP yog tus tswv rau Cisco. Tam sim no, cov tuam txhab hloov pauv tseem ceeb tau txhawb nqa VRRP raws tu qauv hauv lawv cov khoom, tab sis nws yuav siv sijhawm los siv dav.
