Command History
Usage Guidelines The on Keyword
When you use the on keyword, a usable EtherChannel exists only when a port group in on mode is
connected to another port group in the on mode.
You can change the mode for an interface only if it is the only interface that is designated to the specified
channel group.
The on keyword forces the bundling of the interface on the channel without any negotiation.
With the on mode, a usable EtherChannel exists only when a port group in on mode is connected to
another port group in on mode.
If you enter the channel-group command on an interface that is added to a channel with a different
protocol than the protocol you are entering, the command is rejected.
If the interface belongs to a channel, the no form of this command is rejected.
All ports in the same channel group must use the same protocol; you cannot run two protocols on one
channel group.
number Integer that identifies the channel-group. Valid values are from 1 to 256; the
maximum number of integers that can be used is 64.
For Fast EtherChannel groups, the number is an integer from 1 to 4. This
number is the one previously assigned to the port-channel interface.
mode Specifies the EtherChannel mode of the interface.
active Enables Link Aggregation Control Protocol (LACP) unconditionally.
on Enables EtherChannel only.
passive Enables LACP only when an LACP device is detected. This is the default
state.
Release Modification
