Stacking configuration requirements
Before configuring the traditional stack using the CLI, physically connect the devices using stacking
cables. For information about configuring a stack, refer to the
FastIron Ethernet Switch Stacking
Configuration Guide
.
Traditional stack size
A traditional stack can contain a maximum of twelve ICX 7250 devices.
Stacking topologies for traditional stack
Both linear and ring topologies are supported in a traditional stack. In a linear stack topology there is a
connection between each switch that carries two-way communications across the stack. The physical
connection between the devices can use one port (stacked-port) or two ports (stacked-trunk) per trunk.
The stack uses a pair of ports (n, n+1, where n is odd and ranges from 1 through 7) even if there is
only one physical connection between the devices in a stack. The physical connections must be from
an odd-numbered port to an odd-numbered port or an even-numbered port to an even-numbered port.
The following section discusses examples of supported stacking topologies.
NOTE
The figures in the examples show a 24-port device. The 48-port devices show the same behavior for
stacking.
The following figure shows a linear stacking topology example.
