I agree. Connections should be going into to routers but not everyone does that. Single Mac protects everyones traffic. Gary Glissendorf | Network Architect gary.glissendorf@sdncommunications.com -----Original Message----- From: MICE Discuss <MICE-DISCUSS@LISTS.IPHOUSE.NET> On Behalf Of Jay Hanke Sent: Monday, October 31, 2022 8:27 AM To: MICE-DISCUSS@LISTS.IPHOUSE.NET Subject: [MICE-DISCUSS] Proposal: MICE Static MAC address Only I propose we change the MICE required port security settings to be hard filtered for a single static mac address per port. Over the years, we've had several incidents where floods have occurred prior to port being error-disabled during a looping event. -- Jay Hanke, President South Front Networks jayhanke@southfront.io Phone 612-204-0000 ***This message and any attachments are solely for the intended recipient.
