JHA-SWG812MG-20BC
Kakaretso ea Sehlahisoa
12 + 8 + 1 10Gigabit Data Center Switch ke sesebelisoa sa 2 se sa thibeleng se nang le chip ea Broadcom. Ho fana ka matla a ho fetola 258Gbps le ts'ebetso ea ho fetisa 192Mpps, ho fetisa L2 / L3 ka lebelo le feletseng la terata. Matla a eona a marang-rang a feto-fetohang a tiisa botsitso ba marang-rang le ho leka-lekana ha khokahanyo ea mojaro. Ka moralo oa modular, e fana ka likou tsa 12 10G SFP + optical, 8 10/100/1000M RJ45 likoung tsa motlakase, 1 Console port, 1 OOB port port, e fanang ka bandwidth e lekaneng bakeng sa ho kopanya data le phapanyetsano ea data. 'Me e le ho arabela ka mokhoa o feto-fetohang ho litlhoko tsa marang-rang, basebelisi ba ka khetha likou tse loketseng tsa 10G ho ea ka litlhoko tsa bona.Ka bandwidth e phahameng le latency e tlaase, marang-rang a liphaephe., JHA-SWG812MG-20BC e fumanehang ka bongata ba moloko o latelang oa setsi sa data le leru. khomphutha phihlello ea marang-rang, e ka sebelisoa hape bakeng sa li-cafes tse kholo tsa Marang-rang, setsi sa marang-rang sa khoebo, marang-rang a sebaka sa metropolitan, kapa aggregation.
Sehlahisoa Tšobotsi
Tshebetso e tsotehang
1. Ka 258Gbps backplane bandwidth, indasteri e sebetsa ka ho fetisisa (1U TOR);
2. Hardware routing, lebelo la pakete ea terata e fihlile ho 192Mpps, L2 / L3 ho ea pele ka lebelo le feletseng;
3. E khona ho romelloa ho Metropolitan Area Network le ho fana ka theknoloji ea lik'hilomithara tse 'maloa tsa ho qetela.
E Sireletsehile ebile ea Tšepahala
1. Fana ka DOS, DDOS, spoofing le ts'ireletso ea kokoana-hloko;
2. Tšehetsa IEEE802.1x, fana ka netefatso ea basebelisi ba koung, thebe ea marang-rang, taolo ea polokeho, le thekenoloji ea taolo ea maano;
3. Thibela palo e kholo ea mabotho a hokahaneng le boema-kepe, sehokelo sa Ethernet se tlamang ka bongata , ho eketsa bandwidth le redundancy ea sistimi;
4. ACL e matla, e ts'ehetsa ho sefa ha data L2-L4;
5. Lethathamo la taolo ea maano le taolo ea phallo.
E bonolo ts'ebetsong le tlhokomelong
1. Tšehetsa tenyetsehang koung tlhophiso;
2. Tšehetso ea tsamaiso ka Web, SNMP le telnet;
3.Support XModem protocol, sebelisa TFTP/ZMODEM ho ntlafatsa software le ho ntlafatsa BootRom;
4.Support SFP +, hape XFP e lumellanang le morao;
5. Kena kapa u tsoe boemong ba matla a tlaase ho tloha PHY.
Phallo e Matla le Tsamaiso ea Phatlalatso
1. Ho lemoha le ho laola sefefo se phatlalatsoang ka mokhoa o itekanetseng, ho tšehetsa ho lemoha lipakete tsa IGMP, ho fokotsa ka katleho likhohola tsa lipakete tsa khaso;
2. Support Ethernet segokanyimmediamentsi sa sebolokigolo nka 1M e le mohato bolelele bakeng sa ho fokotsa sekhahla.
3. Ts'ehetsa mokhoa o felletseng oa duplex le taolo ea phallo ea halofo ea duplex;
4. Tšehetsa IP multicast le QoS.
