Task
Shut down both the first and second port
to learn the MAC address.
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.
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
Reset interfaces in ERR_Disabled state caused
by a learning limit violation or station move
violation.
Reset interfaces in ERR_Disabled state caused
by a learning limit violation.
Reset interfaces in ERR_Disabled state caused
by a station move violation.
Note: Alternatively, you can reset the interface by shutting it down using the
reenabling it using the command the
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.
