For additional information about configuring MAC limit for an interface on a device thatĭoes not support Enhanced Layer 2 Software (ELS), see Configuring MAC Limiting (non-ELS). MAC limit for an interface on a device that supports ELS, see Configuring MAC Limiting (ELS). For additional information about configuring That the interface be shut down or temporarily disabled. Incoming packets be ignored, dropped, or logged when the limit is exceeded. When you are configuring the maximum MAC limit for an interface, you can choose theĪction that occurs on incoming packets when the MAC limit is exceeded. Interface on the basis of its membership within a VLAN (VLAN membership MAC limit). Of dynamic MAC addresses that can be learned on a single interface, all interfaces, or a specific MAC limiting is configured on Layer 2 interfaces. If an allowed MAC setting conflicts with aĭynamic MAC setting, the allowed MAC setting takes precedence.
The address is not registered outside the VLAN. An allowed MAC address is bound to a VLAN so that
Any MAC address that is not in the list of configured addresses is not learned,Īnd the switch logs an appropriate message. Specifying allowed MAC addresses-You configure the allowed MAC addressesįor an interface. Static MAC addresses do not count toward the limit you specify for dynamic MAC addresses. Of a MAC spoofing attack or a loop in the network. Lead to exhaustion of the switch’s processing resources. Because theĮthernet switching table must be updated for each MAC address move, frequent move events can Updated to reflect the association of the MAC address with the new interface. Learned by the switch, but on a different interface. Move occurs when the switch receives a packet with a source MAC address that has already been The number of MAC address moves that are allowed in a VLAN within one second. MAC move limiting provides additional security by controlling The switch then reverts to flooding the previously-learned MACĪddresses, which can impact performance and introduce security vulnerabilities. Flooding occurs when the number of new MAC addresses thatĪre learned causes the Ethernet switching table to overflow, and previously learned MAC addressesĪre flushed from the table. The switch from flooding of the Ethernet switching table (also known as the MAC forwarding Limiting the number of MAC addresses protects Of MAC addresses that can be learned within a VLAN. MAC limiting enhances port security by limiting the number
