The management network is an Ethernet network to which the management port of each switch connects.
The primary management IP address is assigned to the master node. You can use a terminal emulation program and this IP address to connect to the master for configuration and management.
The alternate management IP addresses allow you to connect to individual nodes from your management network. During normal operation, you connect to the stack using the primary management IP address. However, if the stack is split, you can use the alternate management IP address to connect to the other half of the stack. For more information, see Configuring an Alternate IP Address and Gateway.
After you log in to a master or standby node through the management network, you can Telnet to any other node and control that node as if you were directly connected to it. For more information, see Logging Into a Node From Another Node.
