Kindly suggest me a stable IOS version ?
Here's a handy hint regarding which IOS to choose from:
1. Gold Star - It is just an "indication". It doesn't mean it's stable.
2. Release Date - Don't pick a version if the Release Date is >6 months old. Bugs, vulnerabilities, exploits, etc. Not worth it.
3. Version "number" - Remember what I said about the last character to the IOS version? If it doesn't have a number at the end, avoid that version like a plague.
4. High Numbers - Again, look at the last bit of the IOS version. Does it have a number? If it does, what is this number? Consider something that have a high number at the end. It means that this version has been "improved". Look for the latest version of the train. Examples like 15.2(1)SY7 or 15.1(2)SY12.
5. Rebuilds - AVOID! There are versions that are called "rebuilds". It can be easily identified by the small letter in IOS versions, example like 15.2(1)SY0a or 15.1(2)SY4a.
Once you've "picked" the candidate IOS, it is very important to read the Release Notes. Release Notes not only will have a list of OPEN &/or Fixed bugs but it will have important information about the IOS, such as what platforms are supported, whether or not ROMmon upgrade is required/mandatory/recommended, quirks in IOS upgrades, etc.
Hope this helps.
