Re: Tap and Hub

["Crook, Parker" <Parker_Crook () reyrey com>]

Typically speaking, vendors referring to hubs these days are referring to switches.  Just to double check and make sure 
I hadn't missed the last few years, I asked one of our CCNPs and he gave me a funny look when I asked him about gigabit 
hubs... so yeah, hubs only do 10 mb half-duplex.  Actually, here I started to brainstorm what a gigabit hub's traffic 
would look like and, wow, talk about collision city...

Anyways, yeah, go look at gigabit taps.  A tap is going to copy at line-speed, any traffic going through it to the 
tapped ports and you won't have to worry about numerous issues such as collisions and exceeding the bandwidth of the 
device.

Subject: [Snort-users] Tap and Hub

Hi,

What is the difference between a network hub and a network tap?
Maybe a stupid question, but is there a "gigabit hub" on the market or for
gigabit should I look for a tap?
(span port is not possible in my case...)
Thanks for the info.
