Does all switch..

[ikendo]

Hi guys,

Does all switches brake up collision domain?. I know all cisco does,but what about those Netgear,Linksys,etc?.

And what about broadcast domain?, cisco router brake up B.D right?. So what about those Netgear,Linksys,etc router?

thanks

Yes, a switch is a switch, no matter what vendor. As for Broadcast. They're segmented by layer 3 devices...

Thanks for clearing it up. So the router goes, it only broadcast in each segment?.

oh i forgot to ask one more question. Now say if i have a 12 ports switch. If I use one switch,a hub and i use an cross cable to uplink to my hub. Will the hub has its on collision domain?. Will the hub have less contension?.

Adding a hub does not create another collision domain because a hub does not filter traffic. It does eliminate the dedicated bandwidth that a switch provides because a hub divides the bandwidth with all attached users/devices.

All hubs do is to take whatever comes in on one port, duplicate it, and send it out every other port. They are kind of like repeaters in that sense. Therefore, a hub IS a collision domain and a broadcast domain-- ANYTHING that comes in, goes out everywhere. However, if you plug your hub into one port of the switch, and something else into the other switch ports, the devices on the hub will collide with each other, but not with anything else on the switch.
One other thing: you can use a switch to breakup broadcast domains as well. That is what VLANs are all about. But that takes special configuration, a router to route between the VLANS...... All kinds of fun stuff.

Yeah VLAN part its eazy, i can do that on my 1912-EN switch. But my LAN is way too small for vlan, i have only like 23 machine inculded 3 servers. So vlan no needed.
Anyway thanks for replying..
