Have a requirement to disable a separate port if the primary port ( connected to a firewall ) goes down.
I have a scenario where ih have two links to the internet from two separate X480 switches, I need to advise the ISP that the primary Firewall is down ( firewall not connected directly to the ISP ) the way I am thinking of doing this is some sort of a ACL where if the X480 A sees its FW connection go down , the ACL will run and disable the BGP configure link ( port ) to the ISP , with this link down , the ISP will start directing traffic to my secondary X480 , the ACL should work also when the FW connection is returned , and the primary link to the ISP can then return to operation
