Question On 3750 Asics

tecra810076 · ‎10-17-2012

We have a stack of 3750 switches in a stack.

I am trying to understand the command show platform pm if-numbers

When do the command I get the follwing - I only grabbed two ports the rest are not shown

interface gid gpn lpn port slot unit slun port-type lpn-idb gpn-idb

Fa1/0/9 11 11 9 1/10 1 9 11 local Yes Yes

Fa2/0/9 65 65 9 1/10 2 9 11 remote No Yes

My question is if I understand what I read these ports are on asic 1 port 10.

Now I do the command

sh platform port-asic stats drop port 10 asic 1

I get the following output

My assumption is I am looking at the ASIC on switch 1. How do I look at the drops on switch 2?

Thanks

Hello Dave ,

you can try

show platform port-asic stats drop fastEthernet 2/0/10

or sh platform port-asic stats drop port 10 hopefully it will give you infromation for both Switches.

thanks

I believe that the output from "show platform pm if-numbers" aggregates output from each switch, but some other "show platform" commands must be run directly on the switch in question. Note that each switch in the stack still has it's own ASICs/ports (and the numbers are identical/reused). So in your output above your port Fa1/0/9 is on ASIC 1 of switch1, and your port Fa2/0/9 is on ASIC 1 of switch 2.

So if you want to see portspecific info for FA1/0/9, your command would work:

SWITCH# sh platform port-asic stats drop port 10 asic 1

Then to see the counters for Fa2/0/9, which is on switch 2, try this:

SWITCH# session 2

SWITCH-2# sh platform port-asic stats drop port 10 asic 1

Or this should work as well:

SWITCH# remote command 2 sh platform port-asic stats drop port 10 asic 1

I don't pretend to be a hardware guru, so take with a grain of salt!

cheers
