ICX 7450 stack configuration overview

The following table provides an overview of ICX 7450 stacking capabilities. From FastIron release 08.0.30, 4 x 10-Gbps stacking is available from module 2 as an option.

Table 7 ICX 7450 traditional stacking capability
Stacking capability ICX 7450 Additional information
Topologies supported Ring and linear Refer to ICX 7450 stacking topologies.
Maximum stack size 12 (configured in a traditional stack) Traditional stacking and SPX configurations. Any combination of ICX 7450 devices may be stacked. When a stand-alone ICX 7450 is configured as a PE unit attached to an ICX 7750 control bridge in an 802.1br SPX configuration, scaling is increased. Refer to the Brocade FastIron Switch Port Extender Configuration Guide for more information.
Maximum stacking distance 100 meters, 300 meters, or 10 kilometers, depending on optic Refer to FastIron stacking distances and optics by device for more information.
Stacking ports

Two 40-Gbps ports in rear

or

4 X 10-Gbps ports as an option on front

NOTE
40-Gbps stacking and 4 X 10-Gbps stacking cannot be used simultaneously in the same stack.
Modules 3 and 4, one port each. Four 10-Gbps ports are available as an option when a 4X10GF module is installed in slot 2. Refer to ICX 7450 stacking topologies for module locations.
Default ports

Two ports: 1/3/1 and 1/4/1

NOTE
Default ports can be changed to 1/2/1 and 1/2/3 if a 4X10GF module is installed in slot 2. Use the default-ports command to change the default ports.
NOTE
Default ports are handled differently on PE units in an SPX configuration.
Refer to ICX 7450 stacking topologies for port locations. Refer to Configuring 10 Gbps stacking ports on the ICX 7450 for more information. Refer to Planning to build a stack with 802.1br switch port extender capability for more information about configuring ICX 7450 devices in an SPX configuration.
Reconfigurable ports Use the default-ports and stack-port commands to reconfigure ports. Stacking ports can be reconfigured as data ports. The default-ports command allows you to choose between two sets of stacking ports. The stack-port command allows you to use one or two ports of the chosen set. Refer to configuration examples and Traditional stack CLI commands .
Stack trunks

Two trunks are possible:

1/2/1 to 1/2/2 and 1/2/3 to 1/2/4

Supported on 10-Gbps ports only when a 4X10GF module is present in slot 2. Refer to Creating stack trunks on the ICX 7450 for more information.
Hitless switchover and hitless failover Supported Refer to Hitless stacking.
License requirements No license required for stack-port configuration Premium feature requires trust-based license. Refer to the Brocade FastIron Software Licensing Guide for information.
Configuration options Manual and automatic, including Secure-setup Refer to Traditional stack construction methods.
Access methods TFTP, SCP Software images, boot images, and signatures can be downloaded to a stack using TFTP and SCP. Refer to the Brocade FastIron Software Upgrade Guide for more information.
Traditional stacking CLI These commands are not available on the ICX 7450, except as noted:

default-ports, except when a 4X10GF module is present in slot 2

multi-stack-port, except when a 4X10GF module is present in slot 2

multi-stack-trunk, except when a 4X10GF module is present in slot 2

stack-trunk, except when a 4X10GF module is present in slot 2
