Connecting ICX 6450 and ICX 6430 devices in a stack
can be used for data or uplink 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-trunk command. For more information
about these commands, refer to “Configuring an ICX 6430 and ICX 6450 IronStack” on page 266.
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 10/100/100 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. By
default, without a license at bootup, 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, purchase the
ICX6450-2X10G-LIC-POD license. For more information about enabling ports 2 and 4 to 10-Gbps
port speed, refer to “Licensing for Ports on Demand” on page 208.
Connecting ICX 6430 devices in a stack
ICX 6430 devices have 24 or 48 10/100/100 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.
• You can connect one or both ports in a trunk. Connecting both ports in a trunk increases
stacking bandwidth and provides resiliency.
• You must enable stacking and connect cables properly for the stack to work. The active copper
cable lengths for 1-Gbps ports are 1 m (3.2 ft) and 5 m (16.4 ft). The copper cable lengths for
10-Gbps ports are 1 m (3.2 ft), 3 m (9.8 ft), and 5 m (16.4 ft).
• The default stacking ports are always ports 1 and 3. You can trunk (or un-trunk) ports 1 to 2
and or ports 3 to 4. One or both of the two sets of stacking ports can be trunked (or
un-trunked).
• When creating a trunk, the ports in the same column are always trunked. For ICX 6450
devices, all stack ports must be configured to 10-Gbps port speed to enable trunking. For ICX
6430 devices, all stack ports must be at 1-Gbps port speed to enable trunking.
