About Port Channel Modes

You can configure each SAN port channel with a channel group mode parameter to determine the port channel
protocol behavior for all member ports in this channel group. The possible values for a channel group mode
are as follows:
• On (default)—The member ports only operate as part of a SAN port channel or remain inactive. In this
• Active—The member ports initiate port channel protocol negotiation with the peer port(s) regardless of
The table below compares On and Active modes.

mode, the port channel protocol is not initiated. However, if a port channel protocol frame is received
from a peer port, the software indicates its nonnegotiable status. Port channels configured in the On
mode require you to explicitly enable and disable the port channel member ports at either end if you add
or remove ports from the port channel configuration. You must physically verify that the local and
remote ports are connected to each other.
the channel group mode of the peer port. If the peer port, while configured in a channel group, does not
support the port channel protocol, or responds with a nonnegotiable status, it will default to the On mode
behavior. The Active port channel mode allows automatic recovery without explicitly enabling and
disabling the port channel member ports at either end.
A F port channel is supported only in Active Mode.
