HP 2150 uptime bug

Ddido — Fri, 21 Sep 2007 09:52:55 GMT

It seems that HP 2510-24 are affected by an uptime bug: they came up on August 2 2007, and today 21 September 2007 their uptime reset, 49 days after. Anyway, there wasn't no problem with network at all.

All switches are using latest software Q.11.02.

Best regards,

You aren't imagining things, I just noticed the same on my 2510-24. It is also running Q.11.02

However I should note that the latest is Q.11.04. It's not listed on the web site, but is on the FTP server:

ftp://ftp.hp.com/pub/networking/software/2510-Software-Q1104.zip

Unfortunately it will take 49 days to see if Q.11.04 fixes this "problem" - in all honesty this is cosmetic and not worth losing sleep over once you realize your switch didn't decide to spontaneously reboot.

Sounds like sysUpTime is polling a millisecond counter instead of a centisecond counter. It should usually wrap at 497 days.
