Hello,
I'm diving into switching details and saw the following:
# show controllers cpu-interface
ASIC Rxbiterr Rxunder Fwdctfix Txbuflos Rxbufloc Rxbufdrain
-------------------------------------------------------------------------
ASIC0 0 0 0 0 0 0
ASIC1 0 0 0 0 0 0
ASIC2 0 0 0 0 0 0
ASIC3 0 0 0 0 0 0
ASIC4 0 0 0 0 0 0
ASIC5 0 0 0 0 0 0
ASIC6 0 0 0 0 0 0
Above is an output of 4 switches in a stack:
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
1 28 WS-C3750G-24TS 12.2(46)SE C3750-IPSERVICES-M
* 2 28 WS-C3750G-24TS 12.2(46)SE C3750-IPSERVICES-M
3 28 WS-C3750G-24TS-1U 12.2(46)SE C3750-IPSERVICES-M
4 28 WS-C3750G-24TS-1U 12.2(46)SE C3750-IPSERVICES-M
When my math would be correct, I should see 4 switches with each 2 suppervisors: 4 * 2 = 8 ASIC's. But I only see 7 (0 t'm 6)
Where did my ASIC go?
I have to say that one ASIC doesn't have any sfp's inserted, so it's not in use probably, but is this the reason it's not showing up here?

What are you talking about ?
Each switch has 7 asic things o(f which one need not to care about), one switch at time is stack supervisor, that's it.

Hello p.bevilacqua,
When I read the following paper (page 49), I see 2 asic's for a 24 port 3750, and 3 for a 48 port:
