Static Dynamic Port-channels are statically configured. Port-channels are dynamically configured using Link Aggregation Control Protocol (LACP). Member ports of a LAG are added and programmed into the hardware based on the port ID, instead of the order the ports come up. Load balancing yields predictable results across resets and reloads. Create port-channel You can create a maximum of 128 port-channels, with up to 32 port members per group. Configure a port-channel similarly to a physical interface, enable or configure protocols, or ACLs to a port channel. After you enable the port-channel, place it in L2 or L3 mode. To place the port-channel in L2 mode or configure an IP address to place the port-channel in L3 mode, use the switchport command. • Create a port-channel in CONFIGURATION mode. interface port-channel id-number Create port-channel OS10(config)# interface port-channel 10 Add port member When you add an interface to a port-channel: • The administrative status applies to the port-channel. • The port-channel configuration is applied to the 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 must have the same speed. • An interface must not contain non-default L2/L3 configuration settings. Only the description and shutdown or no shutdowncommands are supported. You cannot add an IP address or 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 802.3ad LACP. 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 a 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 mode on command.

To configure a port for LACP operation, use the channelgroup mode {active|passive} 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.
