Ports in a stack must be reserved to be one of the following port types:
• Network Ports—Also known as uplink ports. These are ports that are
connected to the network.
• Stack Ports—Ports that connect two units in a stack. Stack ports are used
to transfer data and protocol packets among the units.
You must indicate to the system (reserve) which ports you plan to use as stack
ports (in the System Mode and Stack Management page). All ports that are not
reserved to be stack ports, are considered to be network ports.
Stack Port Link Aggregation
When two neighboring units are connected, the ports connecting them are
automatically assigned to a stack LAG. This feature enables increasing the stack
bandwidth of the stack port beyond that of a single port.
