1. Cov keyboards tsis tswj tau
Ua ntej ntawm tag nrho cov, cia peb tham txog unmanaged keyboards. Unmanaged keyboards kuj hu ua fool switches. Cias muab, lawv tsis ncaj qha cov ntaub ntawv, tsuas yog ntsaws rau hauv Internet cable. Qhov hloov pauv tsis tau tswj hwm yog nyob rau hauv cov ntaub ntawv txuas txheej txheej. Nws tuaj yeem txheeb xyuas cov ntaub ntawv MAC chaw nyob hauv pob ntawv cov ntaub ntawv, tom qab ntawd xa mus raws li MAC chaw nyob, thiab sau cov MAC chaw nyob thiab cov chaw nres nkoj sib txuas hauv lub rooj chaw nyob sab hauv ntawm nws tus kheej.

Nws qhov zoo dua yog tias nws yooj yim rau siv, ntsaws thiab ua si, tuaj yeem siv ntau ntawm cov koob, tsim nyog siv rau hauv qhov chaw nrog cov khoom siv PC siab ceev, thiab nws yog pheej yig thiab txuag nyiaj.

2. Tswj Hloov
Lub network tswj kev hloov pauv txhais tau hais tias, qhov hloov pauv uas tuaj yeem tswj hwm los ntawm lub network, muaj peb txoj hauv kev tswj hwm, uas tuaj yeem tswj hwm los ntawm qhov chaw nres nkoj serial, los ntawm Web, thiab los ntawm kev tswj hwm network software. Cov ntaub ntawv ntawm lub network tswj kev hloov pauv yuav raug teeb tsa los ntawm Kev Tswj Xyuas Yooj Yim Network (SNMP). SNMP raws tu qauv yog tam sim no siv dav tshaj plaws network tswj raws tu qauv raws li TCP / IP tes hauj lwm. Nws tuaj yeem ua cov ntaub ntawv chaw nyob, chaw nres nkoj, hom raws tu qauv, kev pabcuam, thiab lwm yam. Lim, feem ntau kuj muaj VLAN faib ua haujlwm.

Lub luag haujlwm ntawm kev tswj hwm kev hloov pauv yog khaws tag nrho cov peev txheej hauv lub network kom zoo. Lub network tswj kev hloov khoom lag luam muab ntau txoj hauv kev tswj hwm network raws li qhov chaw nres nkoj tswj chaw nres nkoj (Console), raws li nplooj ntawv Web, thiab txhawb Telnet chaw taws teeb nkag mus rau lub network. Yog li ntawd, cov thawj coj hauv lub network tuaj yeem ua haujlwm hauv zos lossis thaj chaw deb ntawm lub sijhawm saib xyuas kev ua haujlwm ntawm kev hloov pauv thiab kev ua haujlwm hauv lub network, thiab tswj xyuas cov xwm txheej ua haujlwm thiab kev ua haujlwm ntawm txhua qhov chaw hloov chaw hauv lub ntiaj teb saib.

Dab tsi yog qhov zoo ntawm kev tswj cov keyboards?
* Loj backplane bandwidth, ceev cov ntaub ntawv xa mus ceev;
* Muaj ntau hom chaw nres nkoj muab, thiab cov ntaub ntawv sib txawv xws li SFP, GE, ceev Ethernet, Ethernet, thiab lwm yam tuaj yeem xaiv raws li daim ntawv thov ntawm lub network;
* Txhawb kev faib tawm vlan, cov neeg siv tuaj yeem faib thaj chaw rau cov ntawv thov sib txawv, tswj hwm thiab tswj hwm lub network, thiab ntxiv kev tawm tsam cua daj cua dub;
* Cov ntaub ntawv loj dhau los, cov pob ntawv me me poob qis, thiab qis latency;
* Kev sib txuas ua ke tso cai rau cov keyboards thiab cov keyboards thiab cov keyboards thiab cov servers ua ke los ntawm ntau qhov chaw nres nkoj Ethernet kom ua tiav cov khoom sib npaug;
* Cov ntaub ntawv cov ntaub ntawv ntws tuaj yeem tswj tau raws li qhov chaw, qhov chaw, thiab ntu network;
* Nrog ARP kev tiv thaiv muaj nuj nqi, nws tuaj yeem txhim kho thiab txo kev sib txuas ntawm ARP spoofing;
* Qhov chaw nyob MAC tuaj yeem raug khi;
* Qhov chaw nres nkoj mirroring muaj peev xwm luam tau cov tsheb khiav thiab cov xwm txheej ntawm ib qho chaw nres nkoj mus rau lwm qhov chaw nres nkoj ntawm kev hloov rau kev saib xyuas;
* Txhawb DHCP muaj nuj nqi;
* Cov npe tswj kev nkag tuaj yeem tswj hwm IP cov ntaub ntawv pob khoom, xws li txwv nws txoj kev khiav tsheb, nkag mus, thiab muab QoS, thiab lwm yam;
* Nrog rau kev ruaj ntseg zoo, nws tuaj yeem lim thiab kaw qhov chaw nyob MAC, thiab tuaj yeem tsim cov rooj sib txuas MAC zoo li qub;
* Nws tuaj yeem txhawb IEEE802.1Q thiab VLAN raws li kev siv tshuab chaw nres nkoj. GVRP (GARP, VLAN Registration Protocol) thiab GMRP (GARP Multicast Registration Protocol) koom nrog IEEE802.1QVLAN kuj tau txais kev txhawb nqa dav dav;
* Nrog SNMP muaj nuj nqi, nws tuaj yeem tswj hwm thiab tswj lub network zoo dua;
* Ib qho yooj yim los nthuav thiab hloov pauv daim ntawv thov, nws tuaj yeem tswj hwm los ntawm kev tswj hwm network software, lossis nkag mus rau thaj chaw deb los ntawm nws tus kheej nkag mus, ua kom muaj kev ruaj ntseg thiab kev tswj hwm ntawm lub network.
