Dell EMC SmartFabric OS10 User Guide Release 10.5.1

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.

OS10(config)# interface port-channel 10

Add port member — dynamic LACP

LACP enables ports to dynamically bundle as members of a port-channel. To configure a port for LACP operation, use the channel-group 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.

OS10(config)# interface port-channel 100
OS10(conf-if-po-100)# exit

OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# channel-group 100 mode active
