Does the cascading rule apply to switches? Boe 03-27-06

Hello,

I remember with hubs you couldn't have more than a certain amount for a
network segment. I am curiuos -with switches, you can connect many directly
to one main switch (not daisy chaining) - is daisy chaining or direct to a
main switch better? Is there a cascade rule for switches?

Thanks

Direct is a LOT better from a troubleshooting perspective

> Is there a cascade rule for switches?
Generally know as each port on an Ethernet switch is its own collision
domain ( this is not true of a repeating hub)

The other consideration of course is spanning-tree network diameter in
terms of hops

Depends on the switch.. the newer models like 3560 and the 3750 allow
for stacking and if properly cabled if a switch in the stack goes down
the rest of the stack keeps running without a problem.

The 3750s are really nice because if you telnet into them and configure
them you see the entire port list of the stack vs the older stacks
where you had to hit each switch to configure them.

My comments were rin relation to Ethernet ports; not to internal switch
buses or the like.
