Mohloli oa fektheri Manageable Network Switch - 48+4 10G Management Fiber Ethernet Switch JHA-SW4804MG-52VS - JHA Detail:
48 + 4 10G Tsamaiso ea Fiber Ethernet Switch
JHA-SW4804MG-52VS
Psehlahisoa kakaretso
JHA-SW4804MG-52VS ke sesebelisoa se tloaelehileng sa BCM chip.
Moralo oa modula o fana ka likou tse 48 10/100/1000 tse feto-fetohang le likou tse 4 tse kopaneng tsa terabyte, tse fanang ka bandwidth e lekaneng bakeng sa phapanyetsano ea data lipakeng tsa ho kopanya le mantlha.
Fana ka bokhoni bo phahameng ba phapanyetsano ea bokhoni, pholisi e phethahetseng ea taolo ea ts'ireletso le CPU e sireletsa leano la ho ntlafatsa ho mamellana ha liphoso, le ho netefatsa ts'ebetso e tsitsitseng ea marang-rang le tekanyo ea mojaro oa khokahanyo.
Ho sa le joalo, e ts'ehetsa thibelo ea tlhaselo ea DoS ka boiketsetso le SNMP, IEEE 802.1, sefate se otlolohileng, protocol ea sefate e pharalletseng ka potlako, ho kopanya lihokela le mesebetsi e meng.
Psehlahisoa Likaroloana
1. Tshebetso e a hlolla
2, 176G bandwidth ea sefofane se ka morao
3, Ø routing ea lisebelisoa, lebelo la terata 3 switching packet rate fihla 131 MPPS
4, Ø core e ka tsamaisoa marang-rang a sebaka sa litoropo, 'me e fana ka theknoloji e seng kae ea ho qetela ea 1 km.
5, Ø/IEEE802.3 saese ea pakete ea Ethernet (64 bytes ho isa ho 1522 bytes)
6, Ø lipakete tse kholo ho fihla ho li-byte tse 9216
- E fana ka ts'ireletso khahlano le DOS, ho haneloa ha litšebeletso, spoofing, le livaerase
Ø tshehetso IEEE802.1 x, e fana ka netefatso ya mosebedisi ho latela boema-kepe, thekenoloji ya mesh shield, thekenoloji ya taolo ya polokeho le lenane la taolo ya maano
Ø fokotsa palo ea khokahano e phahameng ea boema-kepe lipakeng tsa moamoheli le sehokelo sa Ethernet bakeng sa tlamahano e mengata, eketsa bandwidth le redundancy ea sistimi.
Ø ACL e matla, e ts'ehetsa L2 - L4 layer data filteringØ
Lethathamo la taolo ea maano, taolo ea phallo
8.Easy ho sebelisa le ho boloka
E ka laoloa ke Web, SNMP joalo-joalo
Ø e tšehetsa protocol ea XModem, e ka sebelisa ntlafatso ea software ea TFTP/ZMODEM le BootRom.
Ø ts'ehetsa SFP +, hammoho le khokahano ea morao-rao ea XFP, jj
9.Sephethephethe se matla le taolo ea khaso
Ho lemoha ka ho iketsahalla le ho hatella sefefo sa khaso, ts'ehetso ea ho lemoha molaetsa oa IGMP, ka mokhoa o atlehang o fokotsa likhohola tsa phatlalatso
Ø e ts'ehetsa mokhoa o felletseng oa duplex le mokhoa oa ho laola phallo ea halofo ea duplex
Ø e tšehetsa sehokelo sa Ethernet ka 1 m e le sekhahla se fokotsang bolelele ba mohato
