Re: MICE port down

by Jay Hanke

If it happens again, you should be able to disable the port on your side and then re-enable it after a minute and the error state should clear.

Yes, it was a MAC address security violation. I assume it'll be fine to post it, so you can find what one is causing you grief.

MICE port down

by Todd Mueller

Could someone please check the MICE port for Velocity Telephone, I saw it go down about 15 minutes ago. I suspect it shut down because there was more than 1 MAC address coming in. I noticed the MAC address for a layer 2 interface from one of our switches showing up in the corresponding VLAN momentarily for some reason, but it is gone now. Thanks! Todd

Well, iOS 14 didn't drop at noon central, 1:00 pm eastern, as expected, maybe in the next hour and 10 minutes, at least according to an update on the following site; https://www.macrumors.com/2020/09/16/when-download-ios-14-ipados-14-time-zo… On Wed, Sep 16, 2020 at 11:05 AM David Farmer <farmer(a)umn.edu> wrote: > > > On Wed, Sep 16, 2020 at 10:39 AM Jay Hanke <jayhanke(a)southfront.io> wrote: > >> On Wed, Sep 16, 2020 at 10:01 AM David Farmer >> <0000000e7948cb21-dmarc-request(a)lists.iphouse.net> wrote: >> > >> > As I'm sure most of you are aware, but just in case anyone misses it; >> > >> > Apple is expected to release iOS 14, iPadOS 14, watchOS 14, and tvOS >> 14, today at approximately noon central time.

These have been big historical bumps. It'll be interesting to see how the traffic pattern changes with more people working from home. IIRC the big bump was in the evening the last couple of updates. -- Jay Hanke, President South Front Networks jayhanke(a)southfront.io Phone 612-204-0000
