Reference Guide
• If a physical interface is a part of a dynamic LAG, the channel-group id command is rejected on that interface.
• You cannot add static and dynamic members to the same LAG.
• There is a dierence between the shutdown and no interface port-channel commands:
• The shutdown command on LAG xyz disables the LAG and retains the user commands.
• The no interface port-channel channel-number command deletes the specied LAG, including a dynamically created
LAG. The interfaces restore and are ready for conguration.
• A maximum of 128 port-channels with up to 16 members per channel are allowed.
Conguration
LACP is enabled globally by default. You can congure aggregated ports with compatible active and passive LACP modes to automatically
link them.
1 Congure the system priority in CONFIGURATION mode (1 to 65535; the higher the number, the lower the priority; default 32768).
lacp system-priority priority-value
2 Congure the LACP port priority in INTERFACE mode (1 to 65535; the higher the number, the lower the priority; default 32768).
lacp port-priority priority-value
3 Congure the LACP rate in INTERFACE mode (default normal).
lacp rate [fast | normal]
4 Save the conguration.

Interfaces
Create a LAG and then add LAG member interfaces. By default, all interfaces are in no shutdown and switchport modes.
1 Create a LAG in CONFIGURATION mode.
interface port-channel port-channel number
2 Enter INTERFACE mode.
