Add port member When you add a port interface to a port-channel: • The port-channel configuration and administrative status are applied to member interfaces. • A port-channel operates in either L2 (default) or L3 mode. To place a port-channel in L2 mode, use the switchport mode command. To place a port-channel in L3 mode and remove L2 configuration before you configure an IP address, use the no switchport command. • All interfaces should have the same speed (recommended). Port-channels can contain a mix of 10G and 40G Ethernet interfaces, but interfaces that are not the same speed as the first channel member in the port-channel are automatically disabled. • An interface should not contain any non-default L2/L3 configuration settings - only the description and shutdown or no shutdowncommands are supported. You cannot add an IP address or a static MAC address to a member interface. • You cannot enable flow control on a port-channel interface - flow control is supported on physical interfaces that are port-channel members. • Port-channels support LACP (802.3ad). LACP identifies similarly configured links and dynamically groups ports into a logical channel. LACP activates the maximum number of compatible ports that the switch supports in a port-channel. If you globally disable spanning-tree operation, L2 interfaces that are LACP-enabled port-channel members may flap due to packet loops. Add port member - static LAG A static port-channel (LAG) contains member interfaces that you manually assign using the channel-group command.

To configure a port for LACP operation, use the channelgroup mode command. Active and passive modes allow LACP to negotiate between ports to determine if they can form a port -channel based on their configuration settings.
