| Apr 27, 2015 at 11:30 | comment | added | Baldrick | It could be a rubbish "security through obscurity" technique, trying to force the SVI to have a MAC address of all zeros which is invalid so no one can communicate with the VLAN 1 instance. I'm not well exerpainced with Nexus switches, do they have a vlan 1 interface that can't be deleted like traditional IOS switches? | |
| Mar 19, 2015 at 2:21 | comment | added | Todd Wilcox | It could be an attempt to disable vlan 1 by someone who mistakenly thought that was a good thing to do on a cisco switch. | |

| Mar 31, 2014 at 12:58 | comment | added | Ben Mason | Is there a Cisco ACE on the subnet? How about a Layer 3 card? We ran into an issue on a Nexus 7k where there was strange interaction between vPC, ACE and pinging SVIs that required statically setting the SVI MAC Address | |

| Mar 7, 2014 at 22:25 | comment | added | belacqua | @Fizzle That is the case -- there are other people with access, and I suspect this was manually put in to address ... something. Initially I discovered this as I was auditing configs and sync between 5Ks. | |
| Mar 7, 2014 at 8:09 | comment | added | Ryan Foley | Are you the only technician that has access to this switch? I'm wondering if someone manually put this in there. If that is a possibility, I may be able to give you additional insight. | |
