EtherChannel MAC Address
All interfaces that are part of the channel group share the same MAC address. This feature makes the
EtherChannel transparent to network applications and users, because they only see the one logical
connection; they have no knowledge of the individual links.
The port-channel interface uses the lowest numbered channel group interface MAC address as the
port-channel MAC address. Alternatively you can manually configure a MAC address for the
port-channel interface. In multiple context mode, you can automatically assign unique MAC addresses
to interfaces, including an EtherChannel port interface. We recommend manually, or in multiple context
mode, automatically configuring a unique MAC address in case the group channel interface membership
changes. If you remove the interface that was providing the port-channel MAC address, then the
port-channel MAC address changes to the next lowest numbered interface, thus causing traffic
disruption.
