ICX 6450 stacking ports and trunks
The ICX 6450 contains four SFP+ ports in slot 2 on the front panel that can be used as uplink (data)
ports or as stacking ports. The following figure shows the ports in slot 2; the top row consists of ports 1
and 3, and the bottom row consists of ports 2 and 4.
FIGURE 35 Stacking ports on the front panel of an ICX 6450 device
• 1- Console port
• 2- Slot 2 (SFP and SFP + uplink or stacking ports)
• 3- Out-of-band management port
• 4- Slot 1 (10/100/1000 Mbps ports)
Ports 1 and 3 are default stacking ports. Default stacking ports have the capability to accept special
stacking packets during a CLI-initiated command sequence of the Secure Setup utility. If ports 1 and 3
are not used as stacking ports, you can use them as data ports. Configuration is not required to use
them as data ports.
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.
