♦Kutariswa kwechigadzirwa:

v Management Gigabit Fiber Switch ndeyechipiri, yechina layer gigabit yakagadziriswa switch, inopa 10 10/100/1000M RJ45 ports uye 16 1000M SFP optical ports. Iyo yakaoma ware inotsigira waya-speed switching yechikamu chechipiri. Vashandisi vanogona kuseta ese marudzi emabasa ekuchinja kuburikidza neEthernet port muWEB. Yakavakwa-muARP uye DOS yekudzivirira system inogona kunyatso dzivirira iyo ARP, DOS uye akasiyana hutachiona kurwisa, uyezve, Yakashongedzerwa neakawanda ane simba maficha: yakazara QoS, inotenderera muti, kudzvinyirira kwedutu, Bandwidth Control, IGMP Snooping, ACL kuwana. control, DHCP snooping etc.

♦Product features:

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: tsigiro yeakawanda QOS zano. 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 Wakatandavara:Tsigira mwero weIEEE 802.1d uye IEEE 802.1w (Rapid Spanning Tree Protocol) uye IEEE 802.1s (Multiple Spanning Tree Protocol).
4. AUTO DOS: dzivirira iyo inotevera DOS kurwisa 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 kurwisa: munhu anorwisa anotumira mapaketi efoge ane yakafanana sosi yechiteshi nhamba uye yekuenda chiteshi nhamba, iyo yakabatwa system inoedza kutumira ruzivo rwekupindura 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: mafashama eiyo inotarirwa sisitimu nemadutu ekutepfenyura, kuitira kuti sisitimu irege kupindura kune zviri pamutemo tsamba.

(5) SYN / SYN-ACK yakafashama: inofashama iyo gomba rakananga system 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. Tsigira basa rechiteshi chezvioni, kuunganidza chiteshi, chiteshi chekumhanya.

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