Could someone confirm the larger scope of this? Our remote switch indeed has static mac ACLs. Unsure how others work. If the goal here is to keep a static mac list on all access ports AND remote switch ports (so my list must be replicated to the core switch)? If so, lets be sure to consider operational issues. I'm unsure how mac ACLs work on arista, but is there a risk to block all mac addresses while the changes is being made if done incorrectly? (think the classic IOS 'switchport trunk allowed vlan 123..')? If this is being done by humans, hoping the procedure is documented and repeatable (a copy paste to do it). Or better yet, but our machine overlords (via NAPALM?) Cheers, -- Chris Wopat Network Engineer, WiscNet wopat@wiscnet.net 608-210-3965
