![]() ![]() The VLAN assignment for a port is triggered only when the source MAC address of its receiving packet exactly matches the MAC address in a MAC-to-VLAN entry. Interface interface-type interface-numberĮnable dynamic MAC-based VLAN assignment.īy default, dynamic MAC-based VLAN assignment is disabled. Mac-vlan mac-address mac-address vlan vlan-id īy default, no MAC-to-VLAN entries exist. They can have a negative impact on each other. As a result, the port will not be dynamically assigned to the target VLAN.Īs a best practice, do not configure both dynamic MAC-based VLAN assignment and automatic voice VLAN assignment mode on a port. The port drops the received packets instead of delivering them to the CPU. In PVST mode, if the target VLAN of a port is not permitted on the port, the port is placed in blocked state. As a result, the port will not be dynamically assigned to the target VLAN.Īs a best practice, do not use dynamic MAC-based VLAN assignment with PVST. In MSTP mode, if a port is blocked in the MSTI of its target VLAN, the port drops the received packets instead of delivering them to the CPU. When dynamic MAC-based VLAN assignment is enabled on a port, the configuration of disabling of MAC address learning does not take effect.Īs a best practice, do not use dynamic MAC-based VLAN assignment with MSTP. If you configure both static and dynamic MAC-based VLAN assignments on a port, dynamic MAC-based VLAN assignment takes effect.Īs a best practice to ensure correct operation of 802.1X and MAC authentication, do not use dynamic MAC-based VLAN assignment with 802.1X or MAC authentication.
