Dell SmartFabric OS10 User Guide Release 10.5.3

A port-channel includes three configuration modes—on, active, and passive.

On

Sets Channeling mode to Static. The interface acts as a member of the static port-channel.

Active

Sets the interface in the Active Negotiating state. LACP runs on any link that is 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 with another port in Active mode or Passive mode.

Passive

Sets the interface in the 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 port-channel with another port in Passive mode.

• There is no dual-membership in static and dynamic port-channels:
  • If a physical interface is a part of a static port-channel, the channel-group id mode {active | passive} command is rejected on that interface.
  • If a physical interface is a part of a dynamic port-channel, the channel-group id command is rejected on that interface.
• You cannot add static and dynamic members to the same port-channel.
• There is a difference between the shutdown and no interface port-channel commands:
  • The shutdown command on port-channel xyz disables the port-channel and retains the user commands.
  • The no interface port-channel channel-number command deletes the specified port-channel, including a dynamically created port-channel. The interfaces restore and are ready for configuration.
• A maximum of 128 port channels with up to 32 members per port channel are allowed.
