Robert's point about only being able to daisy chain up to 2 switches

No I said 3 (three) but I cannot find documentation to back up what I had
thought.
Our network has at least 10 switches all linked
together with redundant links.
I think the following is OK..........
P S----------------------------Switch2--------------------Switch3
R W---------------------------Switch4--------------------Switch5
I I----------------------------Switch6--------------------Switch7
M T---------------------------Switch8--------------------Switch9
A C---------------------------Switch10------------------Switch11
R H---------------------------Switch12------------------Switch13
Y
but not............
S-------Sw2------Sw3-----Sw5----Sw6------Sw7----Sw8------Sw9-----Sw10
W-----------Switch4

Happy to be corrected though as it could make life easier at times.
Where is Michael Moffat? (He works at Allied Tellyson)

I think you're confusing best practices with actually supported. Obviously the
available bandwidth plummets with each switch, but networking limits revolve
around cable, not equipment ( eg max cat 5 run = 100m - but you can run 200m if
there's a switch in the middle, etc ) to the best of my knowledge.

Yup.
The next limit after that comes from the infamous 543 rule.
You can have 5 segments of cable seperated by 4 pieces of equipment of
which ONLY 3 segments are allowed to have other devices (that is, other
than the interconnecting segment devices) on them.
The reason for all of this is, as Steve says, cable-related. The total
maximum length of cable must allow a packet to make a complete round
trip of the entire network within the lifetime of that packet else
network collisions can't be detected.
(Yup, even in the days of switches, we're still constrained by collisions).
Brat.
