All Ethernet ports—other than those used by A-Link networks and the private network on a dual-node ztC Edge system—are considered business-network ports. Guest operating systems use business-network ports to connect to your network.

One business network is the management network, and each PM has a single management network that is referred to as ibiz0 and uses the network labeled P1. The management network accesses the ztC Edge Console and handles miscellaneous management tasks and the quorum server. These management tasks include:

• Sending call-home messages and e-alerts

• Checking the status of licenses

• Each PM's communication with the ztC Edge Console
• Failover function of priv0 (for systems with dual nodes)

• Communication between the two nodes (for systems with dual nodes)

• Communication with the quorum server (if one exists)

You set up the management network when you deploy the system. You can also set up business networks for any business-network ports that are physically connected during deployment. To connect a second business network after the deployment is complete, see Connecting a Second Business Network.
