Add port member
When you add a port interface to a port-channel:
• The port-channel conguration 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 conguration before you congure 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 rst channel member in the port-channel are automatically disabled.
• An interface should not contain any non-default L2/L3 conguration 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 ow control on a port-channel interface — ow control is supported on physical interfaces that are port-channel
members.
• Port-channels support LACP (802.3ad). LACP identies similarly congured 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 ap 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.
OS10(config)# interface port-channel 10

%log-notice:IFM_ASTATE_UP: Interface admin state up.:port-channel10

OS10(conf-if-po-10)# exit
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# channel-group 10

%log-notice:IFM_OSTATE_UP: Interface operational state is up.:port-channel10
Add port member — dynamic LACP
LACP enables ports to be dynamically bundled as members of a port-channel. To congure a port for LACP operation, use the channel-
group mode command. Active and passive modes allow LACP to negotiate between ports to determine if they can form a port -channel
based on their conguration settings.
OS10(config)# interface port-channel 100
OS10(conf-if-po-10)# exit
OS10(config)# interface ethernet 1/1/2
OS10(conf-if-eth1/1/2)# channel-group 100 mode active
Minimum links
Congure minimum links in a port-channel (LAG) that must be in oper up status to consider the port-channel to be in oper up status.
• Enter the number of links in a LAG that must be in oper up status in PORT-CHANNEL mode (1 to 32, default 1).
