Number of switches - 100BaseT

Ethernet timings dictate a maximum (and minimum) cable separation between
nodes. This is also reflected in the number of switches (or hubs) permitted
between nodes. I can find details defining this for 10BaseT networks but
not for 100BaseT. Can anybody help with details of maximum number of
switches?

Apologies if this is not the right newsgroup for this.

TIA

I don't think there's a maximum number of switches, since they're
store-and-forward. My recollection is that the limit on hubs is
five levels. Frankly, I try to keep switches within that limit,
too, since you're going to have some latency associated with each,
which can affect performance. Besides, 5 levels allows a LOT of
devices (enough to overflow the tables in the switches, which is
another issue, BTW).

But I could be wrong -- I haven't studied it closely.
