If the channel group has more than 8 interfaces, the remaining interfaces are in hot standby for the port channel associated with this channel group on the M Series modules. Beginning with Cisco NX-OS Release 5.1, you can bundle up to 16 active links into a port channel on the F Series module. Note When you delete the port channel, the software automatically deletes the associated channel group. All member interfaces revert to their original configuration. You cannot disable LACP while any LACP configurations are present. Port-Channel Modes Individual interfaces in port channels are configured with channel modes. When you run static port channels with no aggregation protocol, the channel mode is always set to on. After you enable LACP globally on the device, you enable LACP for each channel by setting the channel mode for each interface to active or passive. You can configure either channel mode for individual links in the LACP channel group when you are adding the links to the channel group. Note You must enable LACP globally before you can configure an interface in either the active or passive channel mode. Table 6-1 describes the channel modes.

Configuring Port Channels
Information About Port Channels
Figure 6-2
Individual Links Combined into a Port Channel
With LACP, you can bundle up to 16 interfaces in a channel group. If the channel group has more than
8 interfaces, the remaining interfaces are in hot standby for the port channel associated with this channel
group on the M Series modules.
Beginning with Cisco NX-OS Release 5.1, you can bundle up to 16 active links into a port channel on
the F Series module.
Note
When you delete the port channel, the software automatically deletes the associated channel group. All
member interfaces revert to their original configuration.
You cannot disable LACP while any LACP configurations are present.
Port-Channel Modes
Individual interfaces in port channels are configured with channel modes. When you run static port
channels with no aggregation protocol, the channel mode is always set to
on
.
After you enable LACP globally on the device, you enable LACP for each channel by setting the channel
mode for each interface to
active
or
passive
. You can configure either channel mode for individual links
in the LACP channel group when you are adding the links to the channel group.
Note
You must enable LACP globally before you can configure an interface in either the
active
or
passive
channel mode.
Table 6-1
describes the channel modes.
