FIGURE 41 Stacking ports
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
Brocade FastIron Stacking Configuration Guide .
Traditional stack size
A traditional stack can contain a maximum of twelve ICX 7250 devices.
Stacking topologies for a 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.
NOTE
The examples in the following figures show a 24-port device. The 48-port devices show the same behavior for stacking.
The following figure shows a linear stacking topology example.
∙
For the first device in the stack, ports (1/2/1, 1/2/2) are being used as stacked ports.
