Chapter 6 Configuring Port Channels Information About Port Channels Send document comments to [email protected] Figure 6-2 Individual Links Combined into a Port Channel Channel group 1 1/1 1/2 1/3 1/4 Switch A 1/5 1/6 1/7 1/8 Channel group 3 po1 po2 Port channel Hot standby Individual link Suspend X Channel group 2 2/1 2/ 2 2/ 3 2/4 Switch B 2/5 2/6 2/7 2/8 182839 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.
