16+10 Maareynta Gigabit Fiber Switch

JHA-S1016MG-26BC

♦Dulmarka alaabta:

Maaraynta Gigabit Fiber Switch waa lakabka labaad, lakabka afraad ee gigabit la maareeyo, waxa uu bixiyaa 10 10/100/1000M RJ45 dekedaha iyo 16 1000M SFP dekedaha indhaha. Alaabta adagi waxay taageertaa wareejinta xawaaraha siliga ee lakabka labaad. Isticmaalayaashu waxay dejin karaan dhammaan noocyada kala duwan ee hawlaha beddelka iyagoo sii maraya dekedda Ethernet ee WEB. Nidaamka difaaca ee ARP iyo DOS ee la dhisay ayaa si wax ku ool ah u difaaci kara ARP, DOS iyo weerarrada fayraska ee kala duwan, sidoo kale, Waxa kale oo lagu qalabeeyaa sifooyin badan oo awood leh: QoS dhamaystiran, geed dheer, xakamaynta duufaanka, Xakamaynta Bandwidth, IGMP Snooping, ACL helitaanka xakamaynta, DHCP snooping iwm.. Aad ugu haboon ganacsiyada yaryar iyo kuwa dhexdhexaadka ah, shabakada kambaska, iyo codsiyada isku-darka shabakadaha aagga magaalo-madaxda.

♦Tilmaamaha alaabta:

1. Difaaca ARP: shaqada cinwaanka MAC iyo xidhitaanka dekeda iyo shaandhaynta cinwaanka MAC waxay si wax ku ool ah u difaaci kartaa weerarka ARP; DHCP snooping waxay siin kartaa ilaalinta ARP isticmaalayaasha si ay u helaan MAC si firfircoon.
2. Qos: taageerada istaraatijiyad badan oo QOS ah. Iyada oo ku saleysan goobta mudnaanta 802.1p, deked kastaa waxay bixisaa sideed saf oo mudnaanta leh. IP-DSCP waxaa loo qaybin karaa heerar adeeg oo kala duwan iyadoo loo eegayo cinwaanka IP-ga, si loo gaaro QOS dhamaystiran. AUTO VOIP waxay dekeddu u dejin kartaa mudnaanta ugu sarreysa ee calaamadda codka, waxay si weyn u wanaajisaa tayada codka shabakadda IP-ga taleefanka.
3. Geedka dheereeya: Taageer heerka IEEE 802.1d iyo IEEE 802.1w (Protocol-ka degdega ah ee geedaha) iyo IEEE 802.1s (Multiple Spanning Tree Protocol).
4. AUTO DOS: ku difaac weerarka DOS ee soo socda toddobo nooc oo kala duwan.

(1) Weerarka dhulka: weeraryahanku wuxuu soo diraa baakidh been abuur ah oo TCP SYN ah oo qulqulka macluumaadka leh isla isha IP ciwaanka, ciwaanka IP-ga, nidaamka dhibbanuhu wuxuu isku dayaa inuu u soo diro macluumaadka jawaabta laftiisa, taasoo keenta khalkhal nidaamka oo waa curyaan ama dib u bilaabi doona .

(2)Weerar badheedh ah: weeraryahanku waxa uu soo diraa baakado been abuur ah oo leh isla lambarka dekedda iyo lambarka uu ku socdo, nidaamka dhibbanuhu waxa uu isku dayaa in uu u soo diro akhbaarta jawaabta laftiisa, taas oo keenta shilalka nidaamka ama dib u bilaaba.

(3)Weerarka Smurf: weeraryahanku waxa uu isticmaalaa ciwaanka il-baxsan ee bartilmaameedka weerarka si uu ugu hawlgalo habka ping-ga ee ciwaanka baahinta. Kadibna dhammaan martigeliyaha firfircoon ayaa ka jawaabi doona bartilmaameedka, taasoo horseedaysa ciriiri ama carqaladayn shabakad.

(4) Daadka Ping: daadinta nidaamka bartilmaameedka by duufaanada ping-ga, si nidaamku uusan uga jawaabin waraaqaha sharciga ah.

(5)SYN/SYN-ACK daad: ku daadiya nidaamka bartilmaameedka godka SYN ama SYN/ACK xirmo.

(6) Ilaali weerarka TCP ee aan ansax ahayn: Ka hortag daadka xogta ay sababaan xidhmooyinka TCP ee aan ansax ahayn.

(7) Ping of Death Weerar: Waxay soo dirtaa xirmo codsi oo ICMP ah oo aad u weyn ("Ping"), ujeedadeedu waa inay keento gelinta kombuyuutarka bartilmaameedka ah inay buux dhaafaan, si kombuyuutarku u curyaamo.

5. Xakamaynta duufaanka: waxaa lagu dhejin karaa Broadcast, multicast, DLF taraafikada.

6. Xakamaynta gelitaanka ACL: waxa loo isticmaalaa in lagu xakameeyo beddelka baakidhka dekedda, si loo hubiyo in goobta intranet-ku aanay geli doonin isticmaaleyaasha amar la'aan, iyadoo si dadban loo difaaco weerarka ARP.

7. IGMP Snooping: Taageerada nooca IGMP 2 (RFC 2236): IGMP Snooping waxaa loo isticmaalaa in lagu dhiso kooxaha multicast-ka ah si ay u gudbiyaan xirmooyinka multicast si looga fogaado luminta bandwidth marka xirmo multicast ah oo buux dhaafiyey.

8. Taageerida xaqiijinta 802.1x, iyo in la siiyo isticmaalayaasha marin u helka aqoonsiga.

9. shaandhaynta xawaaraha fiilada - Kaydinta - qaabka hore, bixinta qaab-dhismeedka beddelka ee aan xannibin run.

10. Taageer shaqada muraayadda dekedda, ururinta dekedda, xadka xawaaraha dekedda.

11. Taageer dekedda ku salaysan VLAN iyo IEEE802.1Q ku salaysan VLAN .
