Stacking Configuration Requirements; Stacking Cables - Brocade Communications Systems ICX 6430 Hardware Installation Manual

All four ports in slot 2 can be used as stacking ports.
The stacking ports can be grouped into two trunks. Ports 1 and 2 can form a trunk; ports 3 and 4 can
form another trunk. By default, ICX 6450 devices are not configured for trunking.
On the ICX 6450, ports 1 and 3 are 10 Gbps ports. Without a license at bootup, ICX 6450 ports 2 and 4
come up in 10 Gbps port speed in an error disabled state. To enable ports 2 and 4 to 10 Gbps port
speed, you must purchase the ICX6450-2X10G-LIC-POD license. For more information about enabling
ports 2 and 4 to 10 Gbps port speed, refer to the FastIron Ethernet Switch Administration Guide.
Trunking requirements
• You can connect one or both ports in a trunk. Connecting both ports in a trunk increases stacking
bandwidth and provides resiliency.
• If you connect both ports in a trunk, both ports must connect to both ports of one trunk on another
device.
• When configuring a trunk, the ports in the same column are always trunked (port 1 to port 2, port 3
to port 4). One or both of the two sets of stacking ports can be trunked (or untrunked).
• For ICX 6450 devices, all stacking ports must be configured to 10 Gbps port speed to enable
trunking.
NOTE
If you use the Secure Setup utility to set up a mixed stack, the stacking units (ICX 6610 devices and
ICX 6450 devices) are automatically trunked.

Stacking configuration requirements

All configuration methods
Before configuring the mixed stack, physically connect the devices using stacking cables.
Secure Setup utility
To use the 10 Gbps SFP+ ports on the front panel of ICX 6610 devices to connect ICX 6610 devices to
ICX 6450 devices in a mixed stack, configure the SFP+ ports on the ICX 6610 devices to 10 Gbps using
the speed command.
Automatic and manual configuration methods
To connect an ICX 6610 device in the backbone to an ICX 6450 device (peripheral unit), configure the
peri-port command or peri-trunk command on the ICX 6610 device
For information about configuring a stack, see the FastIron Ethernet Switch Stacking Configuration
Guide.
