I have four WISM's in two 6509 chassis running 220.127.116.11 and am going to do an upgrade on them in the next couple of days. I know there are several versions that are not the best at keeping the WISM's up, and I wanted to know what version some of you are running successfully. The issues I have with the current code is the enability to keep them running for more than 30 days at a time. Just about every thirty days one of the four will go down, even though the core says its still up.
Thanks for anything you can lend.
