♦Imveliso ovkwayerview:

v JHA-S2024MG-26BC Series Gigabit eLawulwayo iFayibha Utshintsho lwesibini, umaleko yesine gigabit elawulwa switch. I-Hard Ware ixhasa ukutshintshwa kwe-wire-speed kuluhlu lwesibini. Abasebenzisi banokuseta zonke iintlobo zemisebenzi yokutshintsha nge-Ethernet port kwi-WEB. I-ARP eyakhelwe-ngaphakathi kunye nenkqubo yokukhusela ye-DOS inokukhusela ngokufanelekileyo i-ARP, i-DOS kunye nokuhlaselwa kweentsholongwane ezahlukeneyo. Ngaphezu koko, iiSwitshi ze-JHA-S2024MG-26BC Series zikwaxhotyiswe ngeempawu ezininzi ezinamandla: iQoS ebanzi, umthi ojikelezayo, ukucinezelwa kwesaqhwithi, Ukulawulwa kweBandwidth, IGMP Snooping, ulawulo lokufikelela kwi-ACL, i-DHCP snooping njl. Ilungele kakhulu amashishini amancinci naphakathi, uthungelwano lwekhampasi, kunye nezicelo zokudityaniswa kothungelwano lwengingqi yemetropolitan.

1. Ukukhusela i-ARP: umsebenzi wedilesi ye-MAC kunye nokubopha i-port kunye ne-MAC yokucoca idilesi yokhuseleko inokukhusela ngokufanelekileyo ukuhlaselwa kwe-ARP; I-DHCP snooping inokubonelela ngokhuseleko lwe-ARP kubasebenzisi ukuba bafumane i-MAC ngamandla.

2. Qos: inkxaso yeqhinga leQOS ezininzi. Ngokusekwe kulungiselelo oluphambili lwe-802.1p, izibuko ngalinye libonelela ngemigca esibhozo ephambili. IP-DSCP inokwahlulwa ibe ngamanqanaba enkonzo ahlukeneyo ngokweentloko ze-IP, ukufezekisa i-QOS ebanzi. I-AUTO VOIP inokuseta izibuko kweyona nto iphambili yesiginali yelizwi, iphucule umgangatho welizwi womnatha womnxeba we-IP kakhulu.

3. Umthi oNabileyo: Xhasa umgangatho we-IEEE 802.1d kunye ne-IEEE 802.1w (iProtocol ye-Rapid Spanning Tree Protocol) kunye ne-IEEE 802.1s (iProtocol ye-Multiple Spanning Tree).

4. I-AUTO DOS: khusela olu hlaselo lweDOS lulandelayo ngeendlela ezisixhenxe ezahlukeneyo.

1 .

(2) Uhlaselo lwe-Blat: umhlaseli uthumela iipakethi ezibunjiweyo kunye nenombolo yezibuko yomthombo ofanayo kunye nenombolo yendawo yokuya kuyo, inkqubo yexhoba izama ukuthumela ulwazi lwempendulo kuyo, isiphumo sokuphazamiseka kwenkqubo okanye ukuqala kwakhona.

(3) Uhlaselo lwe-Smurf: umhlaseli usebenzisa idilesi yomthombo we-spoofed ekujoliswe kuyo ukuze aqhube inkqubo ye-ping kwidilesi yosasazo. Emva koko yonke imikhosi esebenzayo iya kuphendula ekujoliswe kuyo, okukhokelela ekuxineni kwenethiwekhi okanye ukuphazamiseka.

(4) Isikhukula se-Ping: ukukhukula kwenkqubo ekujoliswe kuyo yizaqhwithi zosasazo lwe-ping, ukuze inkqubo ingakwazi ukuphendula kwimbalelwano esemthethweni.

(5) I-SYN/SYN-ACK ikhukulisekile: ikhukula inkqubo ekujoliswe kuyo yomngxuma nge-SYN okanye SYN / ACK ipakethe.

(6) Khusela uhlaselo lwe-TCP olungasebenziyo: Thintela ukukhukula kwedatha okubangelwa iipakethi ze-TCP ezingavumelekanga.

(7) I-Ping of Death attack: Ithumela iipakethi zesicelo ze-ICMP ezinkulu kakhulu ("Ping"), injongo yayo kukubangela ukuba i-buffer ye-pump input buffer iphuphume, ukwenzela ukuba ikhompyutha ikhubazekile.

5. Uxinzelelo lwesaqhwithi: inokusetwa kunye neSasazo, i-multicast, i-DLF traffic.

6. Ukulawulwa kokufikelela kwe-ACL: isetyenziselwa ukulawula utshintshiselwano lwepakethi ukusuka kwi-port, ukuqinisekisa ukuba indawo ye-intranet ayiyi kuba nokufikelela kubasebenzisi ngaphandle kwegunya, ngelixa ukhusela ngokungathanga ngqo ukuhlaselwa kwe-ARP.

7. I-IGMP Snooping: Inkxaso ye-IGMP version 2 (RFC 2236): I-IGMP Snooping isetyenziselwa ukuseka amaqela e-multicast ukuhambisa iipakethi ze-multicast ukuphepha ukumosha i-bandwidth xa i-multicast ipakethe igqithise inethiwekhi.

8. Inkxaso ye-802.1x yokuqinisekisa, kunye nokubonelela abasebenzisi ngokufikelela ekuqinisekiseni.

9. Ukucoca i-wire-speed filter - Ukugcinwa - imowudi yangaphambili, ukubonelela ngesakhiwo sokutshintsha esiyinyaniso esingathinteliyo.

10.Ukuxhasa umsebenzi wokubonwa kwezibuko, ukuqokelela izibuko, umda wesantya sezibuko.

11. Ukuxhasa i-port-based VLAN kunye ne-IEEE802.1Q esekelwe kwi-VLAN.
