heh... I just did this last weekend at a local high school i volunteer at sometimes, and I've been doing this a while. The hubs were old and didn't have any error detection/avoidance circuitry, so it took me a minute to figure out what had happened... While we're on the topic of physical ethernet design, don't forget the 5/4/3 rule for 10Mbps. Also, IIRC, the 100Mbps spec requires not more than 2 >100m segments between layer 3 devices. Anyone remember the details? -sd Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=58837&t=58783 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
