Shabakadda Alaab-qeybiyeyaasha ugu Sarreysa Beddelka Case Ip ee Goobta Cctv - 24+2 Maareynta Gigabit Fiber Ethernet Beddelka JHA-S2024MG-26BC - Faahfaahinta JHA:
24+2 Management Gigabit Fiber Ethernet Switch
JHA-S2024MG-26BC
24+2 Gigabit la maamulay Fiber Switch
♦Alaabta oviyodulmar:
v JHA-S2024MG-26BC Taxanaha Gigabit la maamulay Fiber Switches waa labaad, lakabka afraad gigabit la maamulay. 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 kala duwan ee fayraska. Waxaa intaa dheer JHA-S2024MG-26BC Taxanaha Switches sidoo kale ku qalabaysan sifooyin badan oo awood leh: QoS dhamaystiran, geed fidinta, xakamaynta duufaanka, Xakamaynta Bandwidth, IGMP Snooping, ACL helitaanka xakamaynta, DHCP snooping iwm Aad ugu haboon shirkadaha yaryar iyo kuwa dhexdhexaadka ah, shabakada kambaska, iyo codsiyada isku dhafka shabakadaha aagga magaalo-madaxda.
- 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 xeeladaha QOS ee badan. 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 balaadhinta: Taageer heerka IEEE 802.1d iyo IEEE 802.1w (Protocol-ka degdega ah ee geedaha) iyo IEEE 802.1s (Protocol Multiple Spanning Tree).
4. AUTO DOS: ka 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) Weerarka Blat: weeraryahanku wuxuu soo diraa baakado been abuur ah oo leh isla lambarka dekedda iyo lambarka goobta uu u socdo, nidaamka dhibbanuhu wuxuu isku dayaa inuu u soo diro macluumaadka jawaabta laftiisa, wuxuu keenaa shilalka nidaamka ama dib u bilaabo.
(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 aanu nidaamku uga jawaabin waraaqaha sharciga ah.
(5) SYN/SYN-ACK daad: ku daadiya nidaamka bartilmaameedka godka SYN ama baakidh SYN/ACK.
(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 kombayutarka bartilmaameedka ah inay buux dhaafaan, si kombiyuutarku u curyaamo.
5. Xakamaynta duufaanka: waxaa lagu dejin 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.Support shaqada muraayada dekedda, ururinta dekedda, xadka xawaaraha dekedda.
11. Taageer dekedda ku salaysan VLAN iyo IEEE802.1Q ku salaysan VLAN .
