Nexus 9k 9336C-FX2 running nx-os 9.3.5. Upon upgrade from nx-os 9.2.2; I immediately began getting messages about mac learning being disabled on the native vlan (which is distributed world-wide over thousands of switches) due to "to many mac moves". There isn't really any important traffic on this vlan; it basically serves as the "catch all" for any misconfigurations; since all active ports on all switches company wide should have a specifically assigned vlan id.
Since trying to debug *every* potential misconfigured port is basically impossible; I was wondering if there is a way to permanently disable mac address learning for a specific vlan globally on the switch. I understand it can be done at a specific interface level; and apparently for the switch as a whole. But since the switch itself can apparently disable at the vlan level; it seems logical that one could actually configure it to do so permanently via configuration options.
Of course, I realize that logic doesn't always apply; but in this case I'm hoping it does. Maybe it's just a case of not finding it; but searches and a lot of documentation reading so far hasn't helped. Does anyone know if this is possible?
Thanks.
