Raws li cov ntawv thov sib txawv thiab kev ua haujlwm, cov qauv ua haujlwm kub ntxhov muaj peev xwm raug muab faib ua cov txheej txheem, txheej sib sau ua ke, thiab nkag mus rau txheej. Raws li, network keyboards tseem tuaj yeem muab faib ua cov keyboards hloov, kev hloov sib dhos, thiab nkag mus rau cov hloov pauv.
Raws li cov kev ua haujlwm sib txawv thiab kev teeb tsa, cov chaw nres nkoj ntawm cov hloov network txuas tsuas yog muab faib ua ob pawg: uplink ports thiab ports zoo tib yam. Ntawm lawv, qhov chaw nres nkoj uplink yog qhov chaw nres nkoj txuas nrog kev sib sau los yog cov txheej txheej tseem ceeb lossis chaw nres nkoj ntawm WAN Internet egress, uas tsuas yog chaw nres nkoj rau cov ntaub ntawv xa tawm.
Uplink chaw nres nkoj ntawm lub network hloov chaw feem ntau yog qhov chaw nres nkoj siab ntawm lub pob hluav taws xob, uas yog siv los txuas cov cuab yeej lossis lub network hauv zos me me rau lub network loj dua, lossis mus rau lwm cov khoom siv hluav taws xob hauv cov topology (xws li high- tus tes hloov qhov ceev). )). Ordinary ports yog cov ports siv rau cov ntaub ntawv xa khoom. Cov hom sib xws muaj xws li RJ45 chaw nres nkoj, SFP cov chaw nres nkoj, SFP + cov chaw nres nkoj, SFP28 cov chaw nres nkoj, QSFP + cov chaw nres nkoj, thiab QSFP28 cov chaw nres nkoj. Cov pob no tuaj yeem cia siab rau cov kab hluav taws xob sib txawv (xws li cov khoom siv fiber ntau lossis cov sib txuas ua ke). Kab) kom ua tiav kev sib txuas hauv lub network nrog sib txawv ntawm cov nqi sib kis thiab sib kis,
