Task Command Syntax Shut down both the first and second port mac station-move-violation shutdown-both to learn the MAC address. Command Mode INTERFACE To display a list of interfaces configured with MAC learning limit or station move violation actions, use the following command: Task Display a list of all of the interfaces configured with MAC learning limit or station move violation. Command Syntax show mac learning-limit violate-action Command Mode CONFIGURATION Recovering from Learning Limit and Station Move Violations After a learning-limit or station-move violation shuts down an interface, you must manually reset it. To do this, use the following commands: Task Command Syntax Reset interfaces in ERR_Disabled state caused by a learning limit violation or station move violation. mac learning-limit reset Reset interfaces in ERR_Disabled state caused mac learning-limit reset learn-limit-violation by a learning limit violation. [interface | all] Reset interfaces in ERR_Disabled state caused mac learning-limit reset station-move-violation by a station move violation. [interface | all] Command Mode CONFIGURATION CONFIGURATION CONFIGURATION Note: Alternatively, you can reset the interface by shutting it down using the shutdown command and then reenabling it using the command the no shutdown command. Network Interface Controller (NIC) Teaming NIC teaming is a feature that allows multiple network interface cards in a server to be represented by one MAC address and one IP address in order to provide transparent redundancy, balancing, and to fully utilize network adapter resources. Figure 17-1 shows a topology where two NICs have been teamed together. In this case, if the primary NIC fails, traffic switches to the secondary NIC, because they are represented by the same set of addresses. Layer 2 | 309
