24+2 Management Gigabit Fiber Ethernet Switch

JHA-S2024MG-26BC

24+2 Gigabit Yakagadziriswa Fiber Switch

♦Chigadzirwa ovuyerview:

v JHA-S2024MG-26BC Series Gigabit Managed Fiber Swichi ndeyechipiri, yechina layer gigabit yakagadziriswa switch. Hardware inotsigira waya-kumhanya switching yechikamu chechipiri. Vashandisi vanogona kuseta ese marudzi emabasa ekuchinja kuburikidza neEthernet port muWEB. Yakavakwa-muARP uye DOS kudzivirira system inogona kunyatso dzivirira iyo ARP, DOS uye akasiyana kurwisa hutachiona. Uyezve JHA-S2024MG-26BC Series Switches yakashongedzerwawo nezvakawanda zvine simba maficha: yakazara QoS, inotenderera muti, kudzvanya kwedutu, Bandwidth Control, IGMP Snooping, ACL yekuwana control, DHCP snooping etc. Yakakodzera kwazvo kumabhizinesi madiki uye epakati nepakati, campus network, uye metropolitan area network aggregation applications.

1. Kudzivirirwa kweARP: basa reMAC kero uye chiteshi chinosunga uye MAC kero yekuchengetedza kusefa kunogona kudzivirira zvinobudirira kurwiswa kweARP; DHCP snooping inogona kupa ARP dziviriro kune vashandisi kuwana iyo MAC zvine simba.

2. Qos: kutsigirwa kwemaitiro akawanda eQOS. Zvichienderana ne802.1p yekumisikidzwa kwekutanga, chiteshi chega chega chinopa mitsetse masere ekutanga. IP-DSCP inogona kukamurwa kuita akasiyana masevhisi masevhisi zvinoenderana neiyo IP musoro, kuti uwane yakazara QOS. AUTO VOIP inogona kuseta chiteshi chepamusoro-soro chechiratidzo chezwi, kusimudzira kunaka kwezwi retiweki IP foni zvakanyanya.

3. Muti Unotenderera: Tsigira chiyero cheIEEE 802.1d uye IEEE 802.1w (Rapid Spanning Tree Protocol) uye IEEE 802.1s (Multiple Spanning Tree Protocol).

4. AUTO DOS: kudzivirira kunotevera kweDOS kurwiswa nemhando nomwe dzakasiyana.

(1) Kurwiswa kwenyika: munhu anorwisa anotumira akaumbwa TCP SYN mapaketi ekuyerera kweruzivo neiyo yakafanana sosi IP kero, IP kero yekuenda, iyo yekubatwa system inoedza kutumira ruzivo rwekupindura kune yega, inokonzeresa kukanganisa kwehurongwa uye ichaoma mitezo kana kutangazve. .

(2) Blat kurwiswa: anorwisa anotumira mapaketi efoge ane yakafanana sosi yechiteshi nhamba uye yekuenda chiteshi nhamba, iyo yakabatwa system inoedza kutumira ruzivo rwemhinduro kwairi, zvichikonzera kuputsika kwehurongwa kana kutangazve.

(3) Smurf kurwisa: munhu anorwisa anoshandisa spoofed sosi kero yekurwisa chinangwa kushandisa ping process kune yekutepfenyura kero. Ipapo vese vanobatika vanozopindura chinangwa, zvichitungamira kunetiweki kusangana kana kukanganisa.

(4) Ping mafashamo: mafashamo eiyo inotarirwa sisitimu nemadutu ekutepfenyura, kuitira kuti sisitimu irege kupindura kune zviri pamutemo tsamba.

(5) SYN/SYN-ACK yakafashama: inofashamira gomba rakananga sisitimu neSYN kana SYN / ACK packet.

(6) Chengetedza kusakanganiswa kweTCP kurwiswa: Dzivirira mafashama e data anokonzerwa nemapaketi eTCP asina kunaka.

(7) Ping yeKurwiswa kweRufu: Inotumira yakakura kwazvo ICMP yekukumbira mapaketi ("Ping"), chinangwa chayo ndechekuita kuti chinangwa chekombuta chekuisa buffer chifashukire, kuitira kuti komputa iome mitezo.

5. Kudzvinyirira kwemhepo: inogona kuiswa ne Broadcast, multicast, DLF traffic.

6. ACL Access Control: inoshandiswa kudzora kuchinjana kwepakiti kubva pachiteshi, kuve nechokwadi chokuti nzvimbo ye intranet haizove nekuwana kune vashandisi vasina chiremera, asi zvisina kunanga kudzivirira ARP kurwisa.

7. IGMP Snooping: Tsigira IGMP version 2 (RFC 2236): IGMP Snooping inoshandiswa kugadzirisa mapoka emarudzi akawanda ekufambisa mapepa akawanda kuti arege kuparadza bandwidth kana multicast packet inofashukira network.

8. Tsigiro ye802.1x yekusimbisa, uye kupa vashandisi mukana wekuwana chokwadi.

9. Wire-speed filtering - Kuchengetedza - mberi kwemaitiro, kupa chimiro chechokwadi chisina kuvhara.

10.Support basa re port mirroring, port gathering, port speed limit.

11. Tsigira port-based VLAN uye IEEE802.1Q yakavakirwa paVLAN.
