   Table 10. Secondary Node Entries for the Intracluster Interface

   LACP Mode slider	Choose one of the following NIC bonding modes for the Intracluster interface: Active-Backup mode: This mode provides fault tolerance by aggregating two Ethernet interfaces into a single logical channel. When the interface that's currently active goes down, the other interface takes its place and becomes active. LACP mode: This mode aggregates two Ethernet interfaces that share the same speed and duplex settings into a single logical channel. This provides load balancing and higher bandwidth. Note   If you want to enable LACP mode on your appliance's Intracluster interface, do so now. You won't be able to after you complete this wizard. For more information about Cisco DNA Center's implementation of NIC bonding, see NIC Bonding Overview.
