Where did my asic go?

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?

Re: Where did my asic go?

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.

Re: Where did my asic go?

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:

I want to know more about this missing piece to understand it completely.
