This could be blocked by implementing blocking of unknown unicast as shown above.
However traffic will be flooded to all ports in the VLAN. If it does, the packet will be dropped without any log entry or notificationĪlso consider what will happen if you're going to use Shutdown as your Violation Mode, and a new VM is spun up accidentally on this host. So yes, MAC address learning can be disabled even if port-security is used. If a secure MAC address is secured on a port, that MAC address is not allowed to enter on any other port. Live-migration and failover clustering are out of the question.That's the MAC addresses of the vNICs of the parent partition (host) and every child partition (guest) on every external vSwitch You must account for every MAC address on this host.That's a significant amount of overhead if you're going to do that for all hosts. You must manually track them and make sure they don't conflict with each other or get assigned more than once. The MAC address table is a way to map each port to a MAC address. Each host connecting to a switch port will have its MAC address entered into the switch’s MAC address table. To delete all the sticky addresses on an interface or a VLAN, use the no switchport port-security sticky interface interface-id command. Whether 1 Gbps or 10 Gbps Ethernet ports, MAC address learning is performed the same way. To delete a sticky secure MAC addresses from the address table, use the no switchport port-security sticky mac-address macaddress command. You must use Static MACs on all vSwitches on the Hyper-V host. We don’t think much about connecting our hosts to a Cisco switch.
