To release the "bad addresses", log into your DHCP server, find the DHCP subnet in question, select all of the "BAD_ADDRESS" entries and delete them. The access-points should immediately reacquire an IP address and rejoin the controller.
I'm seeing this very similar error on one of our stack of four 3850-48F-L's running IOS-XE 16.3.7, up time is just over 42 weeks. CPU does not seem to spike and it averages around 15-20%. Switch functionality does not seem to be impacted. Example of ...
I am seeing this error excactly every thirty (30) minutes on my 6509-E running IOS 12.2(33)SXI10, so it is not fixed according to the bug reference. Active switch supervisor up time is 4 years, 33 weeks, secondary supervisor up time is 1 year, 38 wee...
We are seeing this message appear about every 2-3 seconds on IOS-XE 03.07.03E. Removing and adding the "snmp-server" commands did not stop these messages from occurring.
@takhzar no change on this issue; I have not tried swapping out any suspect stack cables, and this switch is still operational on IOS 16.3.7 after 1 year, 7 weeks; no user impact, CPU averages 12-15% and no incrementing "changes to link" counters eit...
We have confirmed this bug is affecting us on our 3850-48's with Denali 16.3.5b. The bug has a doomsday timer of around 43 weeks and 4 days, which then causes the active/master switch to lock up. The switch stack sees it as "removed" and must be manu...
om, thanks for the tip, I will try this. I never noticed the date stamp on the stack cables before. An interesting side note is that running the command "show switch stack-ports summary" shows no incrementing changes to link. The cryptic error messag...
My reboot did NOT resolve this error, which continued about once a minute as soon as the switch had fully rebooted. No IOS upgrade was performed either, still running Denali 16.3.5.b.
