Use 15.0(2)SE12 and 15.2(2)E6.
For goodness sake, DON'T "upgrade" the IOS by copying the BIN file across. Read the Release Notes and use the "archive download-sw" automated command. Your job will depend on it!

Hi

We have the following switch also kindly suggest the IOS version.IOS version 15.0(2)SE12  is not avilable in oftware download.Kindly suggest alternate IOS version.I would like to know that, is this issue coming due to IOS poblem or something else.

What I will do for this model ? Shall I use 15.0(2)SE12?

Is it happening due to IOS bug?

I've already provided the response to this question. I shan't repeat.

Hi Leo

 

You are right it should not repeat.

I have read some document where it is telling that Due to IOS bug it may happens.Here is my confusion .I am trying to understand that, for me is it happening due to wrong process of IOS upgrade.

Request you please correct my understanding
