@Vincent-TP 

well, my setup is a er605, then the powered switch... on the powered switch is another switch, the oc200, 650 and 670  all using poe... 

 

looked again today, seems things on the other switch are complaining too, similar to what i posted... 

do i reboot the controller, the switches, everything ?? should i put my er605 back on an autoreboot schedule ? 

also lots of repetative dhcp, not sure if thats a cause or effect ?? 

 

 

 

 

The offline to online time seems consistent with a reboot. Look at power supply issues. Especially PoE power budget, like the total PoE power is at a marginal level, and when some extra CPU processing or whatever pushes it over the edge, everything gets dumped and recycled.

  @RF_Dude thanks 

Rebooted the switch and controller, seems to have fixed the problem. 

There was also a firmware for the switch, both powered and the non poe one, so I also updated both of those... 

The last switch reboot was close to a year ago, 

Power looks good, and well under the limit... Cpu and memory also looked OK... Didn't see any indication of rebooting, but I'll keep it in mind.. 

 

Thanks all, seems to be OK the last few days... 

Always stressful rebooting this stuff... Router takes forever... Oc200 takes like 5 minutes to gain access... After a few minutes I get anxious.. Lol. Use to quicker booting stuff..
