Abahlinzeki Abaphezulu Bekesi Lokushintsha Kwenethiwekhi Ikhamera Ye-Ip Enkambini ye-Cctv - 24+4 Ukuphatha I-Gigabit Switch JHA-S2404MG-28BC - JHA

24+4 Ukuphatha Gigabit Shintsha I-JHA-S2404MG-28BC

♦PumkhiqizoTHEukubuka konke

I-24+4 Management Gigabit Switch iyiswishi evamile engavimbeli. Ihlinzeka ngamachweba angu-24*10/100/1000Base-T, amachweba we-SFP angu-4*1000M; Umthamo wokushintsha we-56Gbps, ukusebenza kokudlulisa okungu-41.644Mpps, amandla okuxhumana aguquguqukayo aqinisekisa ukuzinza kwenethiwekhi kanye nebhalansi yesixhumanisi somthwalo. okunikeza umkhawulokudonsa owanele wokuhlanganisa idatha kanye nokushintshisana kwedatha.Futhi ukuze baphendule ngokuguquguqukayo ezidingweni zenethiwekhi, abasebenzisi bangakhetha izimbobo ze-Gigabit ezifanele ngokwezidingo zabo; Ifanele amabhizinisi amancane naphakathi nendawo, inethiwekhi yekhampasi, amakhefi e-inthanethi kanye nokusetshenziswa kwe-MAN.

♦ UmkhiqizoKeyFizidlakudla

1 . Ukusebenza okuphezulu

 (1）Kuumthamo wendiza engu-56Gbps, ukusebenza okuphezulu kakhulu (1U TOR) kulo mkhakha;

 (2）humzila we-ardware, izinga lokudlulisa iphakethe le-wire speed layer 2 switching lifinyelele ku-41.644Mpps;

 (3）ikwazi ukuthunyelwa ku-Metropolitan Area Network,futhi unikeze ubuchwepheshe obungamakhilomitha amaningi wokugcina;

 (4）I-ethernet / IEEE802.3 usayizi wephakethe (amabhayithi angu-64 ukuya ku-1522 bytes)

 (5）amaphakethe e-jumbo afika ku-9216 bytes

2 . Iphephile futhi Inokwethenjelwa

(1）provide DOS, DDOS, spoofing nokuvikela igciwane

(2）sukwesekwa kwe-IEEE802.1x, ukunikeza ukuqinisekiswa komsebenzisi okusekelwe ethekwini, isihlangu senethiwekhi, ukulawula ukuphepha, nobuchwepheshe bokulawula inqubomgomo

(3）rbeka inani eliphakeme labasingathi abaxhumeke nembobo, isixhumi esibonakalayo se-Ethernet esibopha kaningi , ukwandisa umkhawulokudonsa kanye nokungafuneki kwesistimu

(4）pI-ACL enamandla, isekela ukuhlunga kwedatha ye-L2-L4

(5）inqubomgomoUhlu lokulawula kanye nokulawulwa kokugeleza

3 . Ukulungisa Kalula

(1）sekela ukucushwa kwembobo eguquguqukayo

(2）ekwazi ukuphathwa ngeIwebhu, SNMP,njll

(3）sthuthukisa iphrothokholi ye-XModem, sebenzisa i-TFTP/ZMODEM ukuze uthuthukise isofthiwe futhi uthuthukise i-BootRom

4 . Ukugeleza Okunamandla Nokuphathwa Kokusakaza

(1) thola futhi ulawule ngokuzenzakalelayo isiphepho sokusakaza, sekela ukutholwa kwamaphakethe e-IGMP, unciphise ngempumelelo ukugcwala kwamaphakethe okusakaza.

(2）ssekela imodi egcwele ye-duplex kanye nokulawula ukugeleza kwemodi ephindwe kabili
(3）sisixhumanisi esibonakalayo se-Ethernet esithatha u-1M njengobude besinyathelo sokukhawulela izinga
