16+10 Ukuphatha I-Gigabit Fiber Switch

I-JHA-S1016MG-26BC

♦Ukubuka konke komkhiqizo:

v I-Management Gigabit Fiber Switch iyiswishi ephethwe i-gigabit yesibili, isendlalelo sesine, inikeza amachweba angu-10 10/100/1000M RJ45 kanye namachweba abonakalayo angu-16 1000M SFP. I-hardware isekela ukushintsha kwe-wire-speed kwesendlalelo sesibili. Abasebenzisi bangasetha zonke izinhlobo zemisebenzi yeswishi ngembobo ye-Ethernet ku-WEB. Isistimu yokuzivikela eyakhelwe ngaphakathi ye-ARP ne-DOS ingavikela ngempumelelo i-ARP, i-DOS kanye nokuhlasela kwegciwane okuhlukahlukene, ngaphezu kwalokho, Ifakwe izici eziningi ezinamandla: i-QoS ebanzi, isihlahla esinwebekayo, ukucindezelwa kwesiphepho, Ukulawulwa Komkhawulokudonsa, I-IGMP Snooping, ukufinyelela kwe-ACL. control, DHCP snooping njll.Kufanele kakhulu amabhizinisi amancane naphakathi nendawo, inethiwekhi yekhampasi, kanye nezicelo zokuhlanganisa inethiwekhi yendawo yedolobha elikhulu.

♦Izici zomkhiqizo:

1. Ukuzivikela kwe-ARP: umsebenzi wekheli le-MAC nokubophezela kwechweba kanye nokuhlunga kwekheli le-MAC kungavikela ngempumelelo ukuhlasela kwe-ARP; I-DHCP snooping inganikeza ukuvikelwa kwe-ARP kubasebenzisi ukuze bathole i-MAC ngamandla.
2. I-Qos: ukusekelwa kwamasu amaningi e-QOS. Ngokusekelwe kusilungiselelo sokubalulekile esingu-802.1p, imbobo ngayinye inikeza imigqa ebalulekile eyisishiyagalombili. I-IP-DSCP ingahlukaniswa ngamaleveli esevisi ahlukene ngokuya ngesihloko se-IP , ukuze kuzuzwe i-QOS ebanzi. I-AUTO VOIP ingasetha itheku endaweni ebaluleke kakhulu yesignali yezwi, ithuthukise ikhwalithi yezwi yocingo lwenethiwekhi ye-IP kakhulu.
3. Isihlahla Esinwebekayo:Sekela izinga le-IEEE 802.1d kanye ne-IEEE 802.1w (Iphrothokholi Yesihlahla Esibanzi Esisheshayo) kanye ne-IEEE 802.1s (Iphrothokholi Yezihlahla Ezihlukanisiwe Eziningi).
4. I-AUTO DOS: vikela ukuhlasela kwe-DOS okulandelayo ngamafomu ayisikhombisa ahlukene.

(1) Ukuhlaselwa komhlaba: umhlaseli uthumela amaphakethe e-TCP SYN afojiwe okugeleza kolwazi nekheli le-IP eliwumthombo ofanayo, ikheli lendawo le-IP, uhlelo lwesisulu luzama ukuthumela ulwazi lokuphendula lona ngokwalo, lubangele ukuphazamiseka kohlelo futhi luzokhubazeka noma luqale kabusha. .

(2)I-Blat attack: umhlaseli uthumela amaphakethe omgunyathi anenombolo yembobo yomthombo efanayo kanye nenombolo yembobo yendawo okuyiwa kuyo, isistimu yesisulu izama ukuzithumelela ulwazi lwempendulo, kubangele ukuphahlazeka kwesistimu noma ukuqalisa kabusha.

(3)I-Smurf attack: umhlaseli usebenzisa ikheli lomthombo elikhohlakele lethagethi yokuhlasela ukuze aqhube inqubo ye-ping ekhelini lokusakaza. Bese bonke abasingathi abasebenzayo bazophendula okuqondiwe, okuholela ekuminyanisweni kwenethiwekhi noma ukuphazamiseka.

(4)Izikhukhula ze-Ping: ukukhukhula uhlelo oluqondiwe yiziphepho zokusakaza i-ping, ukuze uhlelo lungakwazi ukuphendula ekubhaleni okusemthethweni.

(5)I-SYN/SYN-ACK igcwele izikhukhula: ikhukhula isistimu eqondiwe yembobo ngephakethe le-SYN noma le-SYN / ACK.

(6) Vikela ukuhlasela kwe-TCP okungavumelekile: Vimbela ukugcwala kwedatha okubangelwa amaphakethe e-TCP angavumelekile.

(7) I-Ping of Death attack: Ithumela amaphakethe esicelo esikhulu kakhulu se-ICMP (“Ping”), inhloso yayo iwukubangela ukuchichima kwebhafa yokufakwayo kwekhompyutha okuhlosiwe, ukuze ikhompuyutha ikhubazeke.

5. Ukucindezelwa kwesiphepho: kungasethwa ngethrafikhi ye-Broadcast, multicast, DLF.

6. Ukulawula Ukufinyelela kwe-ACL: kusetshenziselwa ukulawula ukushintshaniswa kwephakethe kusuka echwebeni, ukuqinisekisa ukuthi isayithi le-intranet ngeke likwazi ukufinyelela kubasebenzisi ngaphandle kwegunya, kuyilapho livikela ngokungaqondile ukuhlasela kwe-ARP.

7. I-IGMP Snooping: Sekela inguqulo 2 ye-IGMP (RFC 2236): I-IGMP Snooping isetshenziselwa ukusungula amaqembu okusakaza okuningi ukuze adlulisele amaphakethe okusakaza okuningi ukuze kugwenywe ukumosha umkhawulokudonsa lapho inethiwekhi yephakethe le-multicast echichimayo.

8. Ukusekelwa kokuqinisekisa okungu-802.1x, kanye nokuhlinzeka abasebenzisi ngokufinyelela ekuqinisekiseni.

9. Ukuhlunga kwesivinini socingo – Isitoreji – imodi yokuya phambili, ehlinzeka ngesakhiwo sokushintsha esingavimbi sangempela.

10. Sekela umsebenzi wokwenza isibuko echwebeni, ukuqoqwa kwechweba, umkhawulo wejubane lechweba.

11. Sekela i-VLAN esekwe ethekwini kanye ne-IEEE802.1Q esekelwe ku-VLAN .
