Add Requirements to How to Use Link Aggregation Control Protocol (LACP) with Cluster Interconnects in Administering an Oracle Solaris Cluster 4.4 Configuration (33099699)

For global zones and zone clusters, the link aggregation that you create in Step 2 requires two links.
For a zone cluster's interconnect, you must create a virtual NIC that uses the link aggregation and the virtual LAN ID (VID) and you must specify the resulting virtual NIC.

Add the following command after the dladm show-phys command in Step 2:
```
# dladm create-vnic -l aggr2 -v 2853 zc_aggr2_vnic1
```
For global zones and zone clusters, you only need to create a single interconnect by configuring either a VLAN for global zones or a virtual NIC for the zone cluster. A second aggregation, VLAN/VNIC, is not required because the single interconnect uses the underlying aggregation for redundancy.
