ports. By default, ICX 6430 and ICX 6450 devices are not configured for trunked stacking. You can
dynamically configure or remove a stacking trunk port configuration using the stack-trunk command or
the multi-stack-trunk command. For more information about these commands, refer to
Configuring an
ICX 6430 and ICX 6450 traditional stack on page 43.
ICX 6450 and ICX 6430 devices support hitless stacking switchover and failover. The secure-setup
utility is supported for ICX 6450 and ICX 6430 devices.
ICX 6430 device supports up to four units in a stack.ICX 6450 device supports up to eight units in a
stack. You cannot mix and match stacking units between ICX 6430 and ICX 6450 devices.
Connecting ICX 6450 devices in a stack
ICX 6450 devices have 24 or 48 10/100/1000 Mbps data ports and 4 ports with 1-Gbps or 10-Gbps SFP
+ fiber uplink and stacking ports. The top row consists of ports 1 and 3, and the bottom row consists of
ports 2 and 4. By default, ports 1 and 3 are 10-Gbps stacking ports and do not have license based
restrictions. However, without a license, ports 2 and 4 boot-up in an error disabled state. To enable
ports 2 and 4 in 10-Gbps port speed, you must purchase the ICX6450-2X10G-LIC-POD license.
ICX 6450 devices are available with 4 1/10-Gbps optical (dual mode) ports. If you want to use more
than two 1-Gbps ports on the 6450 with the optical ports, you must enable the 10-Gbps ports as 1-Gbps
ports for uplinks.
For more information about enabling ports 2 and 4 to 10-Gbps port speed, refer to "Licensing for Ports
on Demand" section in the FastIron Ethernet Switch Administration Guide.
Configuring a 10-Gbps port for a 1-Gbps uplink
If you want to use more than two 1-Gbps ports on an ICX 6450 device with 4 1/10-Gbps optical (dual
mode) ports, you must enable the 10-Gbps ports as 1-Gbps ports for uplinks.
Perform this task to configure a 10-Gbps port for a 1-Gbps uplink on an ICX 6450 device equipped with
4 1/10-Gbps optical (dual mode) ports.

Connecting ICX 6430 devices in a stack
ICX 6430 devices have 24 or 48 10/100/1000 Mbps data ports and 4 1-Gbps SFP fiber uplink and
stacking ports. The default stacking ports are 1 and 3. The 4 1-Gbps ports are not eligible for an
upgrade to 10-Gbps port speed. Trunk stacking configuration is supported for ICX 6430 devices. LAG
configuration is supported for stacking or uplink ports when a pair of 1-Gbps ports are aggregated.
Trunking configuration considerations for ICX 6430 and ICX 6450
devices
The ICX 6430 and ICX 6450 stacking ports are grouped into two trunks. Follow these guidelines for
connecting and configuring the stacking ports:
NOTE
After enabling the ICX 6430 and ICX 6450 trunked stacking ports, it is recommended that you enter the
write memory command to save your configuration.
