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.
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.
