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

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.

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. On Mon, Sep 21, 2020 at 12:24 PM Doug McIntyre <merlyn@iphouse.net> wrote:

Thanks Doug, I will try to track down what the deal is. -----Original Message----- From: MICE Discuss <MICE-DISCUSS@LISTS.IPHOUSE.NET> On Behalf Of Doug McIntyre Sent: Monday, September 21, 2020 12:25 PM To: MICE-DISCUSS@LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] MICE port down On Mon, Sep 21, 2020 at 12:21:35PM -0500, Todd Mueller wrote:
