Dotaz: dvouportová , čtyřportová síťová karta

[mrak-o-plash]

Hezký den,

chtěl bych se zeptat, jelikož nemám zkušenost, možná trochu trivální dotaz - jak fungují dualportové / čtyřportové síťové karty ? Uvidím v systému (Linux) kartu jako 2 / 4 síťové karty ? Takže budu moci každé nastavit vlastní IP adresu, zkrátka jakobych v systému měl více síťových karet ?

Díky.

Ano, budete mít dvě/čtyři nezávislé síťové karty se stejným ovladačem a různými MAC adresami (většinou hned po sobě).

Nevim jak jsou na tom viceportove karty od Intelu, ale starsi 4-portove 100Mbps PCI karty byly casto resene tak, ze na nich byl PCI bridge a pak ctyri nezavisle sitovkove chipy, takze elektronicky to byly v podstate 4 nezavisle sitovky za jednim PCI bridgem.

Zajimave, jednu takovou mam v praci v pc a vazne to tak je, Tohle je 4portova Intel sitovka do PCI-X v kratkem PCI slotu:
