how to analyze the output of "sh ver" on a stack switch?

Mohit Chauhan · ‎11-03-2011

Hi Friends,

Sometimes basic things make you go round and round. I am trying to understand the total memory, its current available free space and and the same for the flash memory.

Now i had taken "sh ver" & "sh flash" output and was trying to add the memory figures together to reach to a conclusion that the stack has total of say "x" of flash memory and "y" amount of memory.

Below is the output taken for an example:

Hi Mohit,

The stack will show you for the details like show version and show flash for all switches like switch and switch 02 like that...

So what you have the above information from show version and show flash you can get to analyze the details.

Please rate the helpfull posts.

Hi Naidu

Would be great help if you could explain that using my example that i had pasted. thats the reason i had mentioned the complete output so that we can make concept more clearer.

cheers!

Sometimes basic things make you go round and round. I am trying to understand the total memory, its current available free space and and the same for the flash memory.

You have two switches in a stack. So to check what available flash memory you have per switch do the following:

1. "sh switch status" - This will tell you which switch is stack member number 1, 2, and so on;

2. "dir flash1:" or "dir flash2:" (and so on) - You get the message.

Hi Mohit,

It seems you have two switches in one stack.
You have following IOS version 12.2(55)SE1
In the first switch you have total 15998976 bytes memory and free 3016704 bytes
In second switch you have total 27998208 bytes and free 14903808 bytes.

And as leo said, you can use that show commands to get the info.
