BPDU Tus Saib Xyuas feature yog siv los tiv thaiv Layer 2 Spanning Tree Protocol (STP) Topology los ntawm BPDU hais txog kev tawm tsam. Thaum a BPDU Tus Saib Xyuas enabled chaw nres nkoj txais BPDU los ntawm cov khoom siv txuas nrog, BPDU Tus Saib Xyuas disables qhov chaw nres nkoj thiab lub xeev chaw nres nkoj hloov mus rau Errdisable xeev.
Kuj paub yog, PortFast Bpdu tus neeg saib xyuas yog dab tsi?
PortFast BPDU tiv thaiv tiv thaiv lub voj los ntawm kev txav qhov chaw nres nkoj uas tsis yog qhov chaw nres nkoj mus rau hauv lub xeev errdisable thaum a BPDU tau txais ntawm qhov chaw nres nkoj. Thaum koj qhib BPDU tiv thaiv ntawm qhov hloov, spanning ntoo kaw PortFast -configured interfaces uas tau txais BPDUs es tsis txhob muab tso rau hauv lub spanning ntoo thaiv lub xeev.
Tsis tas li ntawd, Bpdu filtering yog dab tsi? BPDU lim yog ib tug feature siv los lim xa lossis txais BPDUs ntawm ib qho kev hloov pauv. Nws yog qhov muaj txiaj ntsig zoo ntawm cov chaw nres nkoj uas tau teeb tsa ua cov chaw nres nkoj portfast vim tsis tas yuav xa lossis tau txais ib qho BPDU cov lus ntawm cov chaw nres nkoj no. BPDU lim tuaj yeem teeb tsa thoob ntiaj teb lossis hauv qab theem interface.
Xav txog qhov no, Bpdu sawv cev rau dab tsi?
choj raws tu qauv data unit
Dab tsi yog qhov txawv ntawm Bpdu guard thiab Bpdu lim?
BPDUs tso cai rau cov keyboards kom tau txais cov ntaub ntawv hais txog ib leeg. BPDU lim yuav tiv thaiv inbound thiab outbound BPDU tab sis yuav tshem tawm lub xeev portfast ntawm qhov chaw nres nkoj yog tias a BPDU tau txais. Ua kom tau BPDU lim dej ntawm ib qho interface yog tib yam li disabling spanning ntoo ntawm nws thiab tuaj yeem ua rau spanning-ntoo loops.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv hloov tus yuam sij zais cia uas siv los xyuas kom meej qhov tsis pub lwm tus paub ntawm cov lus?
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Puas yog Lstm saib xyuas lossis tsis saib xyuas?
Lawv yog ib txoj kev kawm uas tsis muaj kev saib xyuas, txawm li cas los xij, lawv raug cob qhia siv cov kev kawm saib xyuas, hu ua tus saib xyuas tus kheej. Lawv feem ntau raug cob qhia ua ib feem ntawm cov qauv dav dav uas sim ua kom rov tsim cov tswv yim
