stacking vs trunking

[farish]

سلام
لطفا براي من فرق stacking port و uplink و trunk رو توضيح بدين و همينطور محدوديتها رو ، مثلا طول كابل stack چقدر ميتونه باشه ، آيا من ميتونم سوييچهايي رو كه در دو طبقه مختلف هستند stack كنم؟ و اصلا مزاياي هر كدوم چيه؟
سپاس

عنوان ویرایش شد(بنظر من stacking Vs uplink مقایسه اشتباهی هست)

برای stack باید توی یه rack باشند و در ضمن باید stackable هم باشن
این عکس ها کاملا گویاست









ولی شما میتونید در طبقات مختلف trunk راه بندازید و سوییچ ها رو بهم وصل کنید..توضیحات تئوری بیشتر یه سرچ توی گوگل هزاران مطلب میده بهتون
uplink هم پورتی هست که switchها رو بهم وصل میکنیم

uplink port A port on a network hub or switch that is used to connect to other hubs and switches rather than an end station

What is the Uplink port on a router, hub, or switch for ?


An uplink port on a hub/switch/router (or any other network device) is simply an Ethernet port where the Receive (Rx) and the Transmit (Tx) signals are swapped by crossing the Transmit and Receive twisted-pair wires

This lets the Transmit signal (and twisted-pair) on one device correctly connect to the Receive connection on the other device and vice-versa, allowing for stacking similar devices, or simply expanding the number of ports

The Uplink feature is often implemented by a shared port, meaning one port with two different jacks (usually next to each other). Note that you should never plug something into both the normal and shared uplink port at the same time in such devices ! Some newer devices implement "auto MDI/MDI-X", a feature that automatically figures out how to connect with whatever is plugged into it

An uplink port is essentially a substitute for a crossover cable, it has the same functionality


---------------------
When your connecting a hub to a hub or a switch to a switch - you don't have to use crossover cables if the hub or switch has an UPLINK port. Simplify things by choosing devices that have UPLINK ports

When your connecting a hub to a hub or a switch to a switch using an uplink port, connect one end of a straight through cable to an UPLINK port and the other end of the cable to a standard port. Remember - you are essentially swapping the TX and RX pairs on ONE end of the cable only. This is why you connect one end of the cable to an uplink port and the other end to a standard port
