♦Sehlahisoa sa ovlemaikutlo:
v JHA-S2024MG-26BC Series Gigabit Managed Fiber Switches ke ea bobeli, ea bone lera gigabit tsamaisoa switjha. Hardware e tšehetsa terata-speed switching ea lera la bobeli. Basebelisi ba ka hlophisa mefuta eohle ea mesebetsi ea switch ka har'a boema-kepe ba Ethernet ho WEB. Sistimi ea ts'ireletso ea ARP le DOS e hahiloeng kahare e ka sireletsa ARP, DOS le tlhaselo e fapaneng ea vaerase. Ho feta moo, JHA-S2024MG-26BC Series Switches e boetse e na le likarolo tse ngata tse matla: QoS e felletseng, sefate se pharalletseng, khatello ea sefefo, Taolo ea Bandwidth, IGMP Snooping, taolo ea phihlello ea ACL, DHCP snooping joalo-joalo. E loketse haholo likhoebo tse nyane le tse mahareng, marang-rang a khamphase, le lits'ebetso tsa ho kopanya marang-rang a sebaka sa metropolitan.
- Tšireletso ea ARP: mosebetsi oa aterese ea MAC le ho tlama ha koung le ho hloekisa aterese ea MAC ho ka sireletsa tlhaselo ea ARP ka katleho; DHCP snooping e ka fana ka tšireletso ea ARP bakeng sa basebelisi ho fumana MAC ka matla.
2. Qos: tšehetso bakeng sa mekhoa e mengata ea QOS. Ho ipapisitsoe le tlhophiso ea 802.1p, boema-kepe bo bong le bo bong bo fana ka mela e robeli ea bohlokoa. IP-DSCP e ka aroloa ka mekhahlelo e fapaneng ea lits'ebeletso ho latela sehlooho sa IP, ho fihlela QOS e felletseng. AUTO VOIP e ka beha boema-kepe boemong ba bohlokoa ka ho fetisisa ba lets'oao la lentsoe, ea ntlafatsa boleng ba lentsoe la mohala oa marang-rang oa IP haholo.
3. Sefate se Opang: Tšehetsa maemo a IEEE 802.1d le IEEE 802.1w (Protocol ea Rapid Spanning Tree) le IEEE 802.1s (Protocol ea Multiple Spanning Tree).
4. AUTO DOS: sireletsa tlhaselo e latelang ea DOS ka mefuta e supileng e fapaneng.
(1) Tlhaselo ea mobu: mohlaseli o romela lipakete tsa TCP SYN tse entsoeng ka tlhahisoleseding tse nang le aterese e tšoanang ea IP, aterese ea sebaka sa IP, tsamaiso ea mahlatsipa e leka ho romela tlhahisoleseding ea karabo ho eona, e bakang tšitiso ea tsamaiso 'me e tla holofala kapa e qale hape. .
(2) Tlhaselo ea Blat: mohlaseli o romella lipakete tse ferekaneng tse nang le nomoro ea boema-kepe e tšoanang ea mohloli le nomoro ea boema-kepe, sistimi ea mahlatsipa e leka ho romella tlhaiso-leseling ea karabo ho eona, ho fella ka ho senyeha ha sistimi kapa ho qala bocha.
(3) Tlhaselo ea Smurf: mohlaseli o sebelisa aterese ea mohloli oa spoofed ea sepheo sa tlhaselo ho sebelisa ts'ebetso ea ping ho aterese ea phatlalatso. Joale mabotho ohle a sebetsang a tla arabela sepheo, se lebisang ho tšubuhlellano ea marang-rang kapa tšitiso.
(4) Ping moroallo: ho phalla tsamaiso ea sepheo ke lifefo tsa ping, e le hore tsamaiso e se ke ea arabela mangolong a nepahetseng.
(5) SYN / SYN-ACK e tletse likhohola: likhohola tsamaiso ea sekoti ea sekoti ka SYN kapa SYN / ACK pakete.
(6) Sireletsa tlhaselo e sa nepahaleng ea TCP: Thibela likhohola tsa data tse bakoang ke lipakete tsa TCP tse sa sebetseng.
(7) Ping ea Tlhaselo ea Lefu: E romela lipakete tse kholo haholo tsa ICMP ("Ping"), sepheo sa eona ke ho etsa hore "buffer" ea ho kenya letsoho ea k'homphieutha e phalle, e le hore k'homphieutha e shoele litho.
5. Khatello ea sefefo: e ka behoa ka sephethephethe sa Broadcast, multicast, DLF.
6. ACL Access Control: e sebelisetsoang ho laola phapanyetsano ea pakete ho tloha koung, ho etsa bonnete ba hore sebaka sa intranet se ke ke sa fihlella ho basebelisi ba se nang matla, ha se ntse se sireletsa tlhaselo ea ARP ka tsela e sa tobang.
7. IGMP Snooping: Tšehetso ea IGMP version 2 (RFC 2236): IGMP Snooping e sebelisetsoa ho theha lihlopha tse ngata ho fetisetsa lipakete tse ngata ho qoba ho senya marang-rang ha marang-rang a mangata a phallang.
8. Ts'ehetso bakeng sa netefatso ea 802.1x, le ho fa basebelisi monyetla oa ho fumana netefatso.
9. Ho hloekisa ka lebelo la mohala - Ho boloka - mokhoa oa ho ea pele, ho fana ka mohaho oa 'nete oa ho fetola o sa thibeleng.
10.Tsehetsa mosebetsi oa seipone sa boema-kepe, ho bokella koung, moeli oa lebelo la koung.
11. Tšehetsa VLAN e thehiloeng koung le IEEE802.1Q e thehiloeng ho VLAN .
