Modes

A LAG includes three configuration modes — on, active, and passive.

On
Sets the Channeling mode to Static. The interface acts as a member of the static LAG.
Active
Sets the interface in the Active Negotiating state. LACP runs on any link configured in this mode. A port in Active mode automatically initiates negotiations with other ports by using LACP packets. A port in Active mode can set up a port-channel (LAG) with another port in Active mode or Passive mode.
Passive
Sets the interface in an Inactive Negotiating state, but LACP runs on the link. A port in Passive mode also responds to negotiation requests (from ports in Active mode). Ports in Passive mode respond to LACP packets. A port in Passive mode cannot set up a LAG with another port in Passive mode.
  • There is no dual-membership in static and dynamic LAGs:
    • If a physical interface is a part of a static LAG, the channel-group id mode active command is rejected on that interface.
    • 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 difference 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 specified LAG, including a dynamically created LAG. The interfaces restore and are ready for configuration.
  • A maximum of 128 port-channels with up to 16 members per channel are allowed.
