24 + 2 Management Gigabit Fiber Ethernet Switch JHA-S2024MG-26BC 24+2 Gigabit Managed Fiber Switch ♦ Zowonetseratu za mankhwala: v JHA-S2024MG-26BC Series Gigabit Managed Fiber Switches ndi yachiwiri, yachinayi wosanjikiza gigabit yoyendetsedwa ndi switch. Hardware imathandizira kusintha kwa waya-liwiro la gawo lachiwiri. Ogwiritsa ntchito amatha kukhazikitsa mitundu yonse ya ntchito zosinthira kudzera pa doko la Ethernet mu WEB. Omangidwa mu ARP ndi DOS chitetezo chitetezo amatha kuteteza ARP, DOS ndi ma virus osiyanasiyana. Komanso JHA-S2024MG-26BC Series Switches ilinso ndi zinthu zambiri zamphamvu: QoS yokwanira, mtengo wotambasula, kuponderezana kwa mphepo yamkuntho, Bandwidth Control, IGMP Snooping, ACL access control, DHCP snooping etc. Oyenera kwambiri mabizinesi ang'onoang'ono ndi apakatikati, campus network, ndi ntchito za metropolitan area network aggregation. Chitetezo cha ARP: ntchito ya adilesi ya MAC ndi kumanga doko ndi kusefa kwa adilesi ya MAC kumatha kuteteza bwino kuukira kwa ARP; DHCP snooping ikhoza kupereka chitetezo cha ARP kwa ogwiritsa ntchito kuti apeze MAC mwamphamvu. 2. Qos: kuthandizira njira zingapo za QOS. Kutengera ndi 802.1p choyambirira, doko lililonse limapereka mizere isanu ndi itatu. IP-DSCP ikhoza kugawidwa m'magulu osiyanasiyana a utumiki malinga ndi mutu wa IP, kuti mukwaniritse QOS yokwanira. AUTO VOIP ikhoza kuyika doko kukhala patsogolo kwambiri pa siginecha yamawu, kukweza mawu amawu amafoni a IP kwambiri. 3. Mtengo Wotambalala: Thandizani muyezo wa IEEE 802.1d ndi IEEE 802.1w (Protocol ya Rapid Spanning Tree) ndi IEEE 802.1s (Protocol ya Multiple Spanning Tree). 4. AUTO DOS: tetezani kuukira kwa DOS kotsatiraku ndi mitundu isanu ndi iwiri. (1) Kuukira kwamtunda: wowukirayo amatumiza mapaketi achinyengo a TCP SYN azidziwitso ndi adilesi yomweyi ya IP, adilesi yolowera IP, wovutitsidwayo amayesa kutumiza zidziwitso kwa iwo okha, kumabweretsa kusokonezeka kwadongosolo ndipo adzapuwala kapena kuyambiranso. . (2) Blat attack: wowukirayo amatumiza mapaketi abodza okhala ndi nambala yofananira ya doko ndi nambala yolowera, wovutitsidwayo amayesa kutumiza zidziwitso kwa iwo okha, zomwe zimapangitsa kuwonongeka kwadongosolo kapena kuyambitsanso. (3) Smurf attack: wowukirayo amagwiritsa ntchito adilesi ya spoofed ya chandamale kuti agwiritse ntchito njira ya ping ku adilesi yowulutsa. Ndiye makamu onse ogwira ntchito adzayankha chandamale, zomwe zimabweretsa kusokonezeka kwa maukonde kapena kusokonezeka. (4) Ping kusefukira: kusefukira kwa chandamale dongosolo ndi ping kuwulutsa mkuntho, kotero kuti dongosolo sangathe kuyankha makalata ovomerezeka. (5) SYN / SYN-ACK yasefukira: kusefukira kwa dzenje lolowera ndi SYN kapena SYN / ACK paketi. (6) Tetezani kuukira kosavomerezeka kwa TCP: Pewani kuchuluka kwa data chifukwa cha mapaketi olakwika a TCP. (7) Ping of Death attack: Imatumiza mapaketi a pempho la ICMP lalikulu kwambiri ("Ping"), cholinga chake ndikupangitsa kuti buffer yolowera pakompyuta isefukire, kotero kuti kompyutayo idapuwala. 5. Kuponderezedwa kwa mphepo yamkuntho: ikhoza kukhazikitsidwa ndi Broadcast, multicast, DLF traffic. 6. ACL Access Control: amagwiritsidwa ntchito poyang'anira kusinthanitsa kwa paketi kuchokera ku doko, kuonetsetsa kuti malo a intranet sadzakhala ndi mwayi kwa ogwiritsa ntchito opanda ulamuliro, pamene akuteteza mwachindunji kuukira kwa ARP. 7. IGMP Snooping: Thandizo la IGMP version 2 (RFC 2236): IGMP Snooping imagwiritsidwa ntchito poyambitsa magulu a multicast kuti atumize mapaketi ambiri kuti asawononge bandwidth pamene mapaketi ambiri akusefukira. 8. Thandizo la kutsimikizika kwa 802.1x, ndikupatsa ogwiritsa ntchito mwayi wotsimikizira. 9. Kusefa kwawaya-liwiro - Kusungirako - njira yopita patsogolo, kupereka mawonekedwe enieni osatsekereza kusintha. 10.Thandizani ntchito yowonetsera doko, kusonkhanitsa madoko, malire othamanga. 11.
