Choosing an IOS

I am new to Cisco and a bit confused by IOS version selection. Does it make the most sense to upgrade to the most recent and stable IOS for a particular device? How about IPBASE vs. IPSERVICES vs. xxxx?

Re: Choosing an IOS

Recent does not always equate with Stable.

Code choices should generally be driven by your business requirements & the tolerance for uptime in your particular environment (to evaluate your level of freedom, consider how resilient your network is in the first place -- e.g. does maintenance on a node take your network out of service or not?).

- feature sets, check CCO there are a few good powerpoints on how the feature licensing is broken down. License for what you need. If a train of code does not have features in it you don't need to begin with, then you don't have to deal with bugs about them.

- "latest/greatest" is sometimes a pitfall. Use Cisco's SafeHarbour testing validations as a guideline.

- avail yourself of published Release Notes and bug-scrub any release you are considering using the BugTool before you roll it out into production usage.

- if you are under any audit requirements to address security defects in xxx period of time, evaluate risk depending on your situation

- follow your change & release management processes (or develop them if you do not have them)

- TEST TEST TEST then VERIFY VERIFY VERIFY

Good luck!
