   Note

   If you opted to configure the Enterprise and Internet Access interfaces on the same port, complete this step and then continue to Step 2e (which describes how to configure your Management interface). If you opted to configure the Enterprise and Management interfaces on the same port, complete this step and then skip ahead to Step 2f (which describes how to configure your Internet Access interface). If you opted to configure the Enterprise, Management, and Internet Access interfaces on the same port, complete this step and then skip ahead to Step 2g.

   Table 10. Secondary node entries for the Intracluster interface

   LACP Mode slider	Select one of these 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. Important   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 Catalyst Center's implementation of NIC bonding, see NIC bonding overview.
