Cisco Nexus 5000 Series - Tracing Traffic Flow in a vPC Topology

channel-group (Ethernet)
To assign and configure a physical interface to an EtherChannel, use the channel-group command. To remove
the channel group configuration from the interface, use the no form of this command.
channel-group number [force] [mode {active| on| passive}]
no channel-group [ number ]
Syntax Description
Number of channel group. The number range is from
1 to 4096. Cisco NX-OS creates the EtherChannel
associated with this channel group if the EtherChannel
does not already exist.
number
(Optional) Specifies that the LAN port be forcefully
added to the channel group.
force
(Optional) Specifies the EtherChannel mode of the
interface.
mode
Specifies that when you enable the Link Aggregation
Control Protocol (LACP), this command enables
LACP on the specified interface. The interface is in
an active negotiating state, in which the port initiates
negotiations with other ports by sending LACP
packets.
active
This is the default channel mode. Specifies that all
EtherChannels that are not running LACP remain in
this mode. If you attempt to change the channel mode
to active or passive before enabling LACP, the switch
returns an error message.
After you enable LACP globally, by using the feature
lacp command, you enable LACP on each channel
by configuring the channel mode as either active or
passive. An interface in this mode does not initiate
or respond to LACP packets. When an LACP attempts
to negotiate with an interface in the on state, it does
not receive any LACP packets and becomes an
individual link with that interface; it does not join the
channel group.
The default mode is on.
