ICX 7250 Stack Configuration Overview

The following table provides an overview of ICX 7250 stacking capabilities.

ICX 7250 Stacking Capability

Stacking Capability ICX 7250 Additional Information
Topologies supported Ring and linear Refer to ICX 7250 stacking topologies.
Maximum stack size 12 units Stacking and SPX configurations. Any combination of ICX 7250 devices may be stacked. When a stand-alone ICX 7250 is configured as a PE unit attached to a control bridge in an 802.1br SPX configuration, scaling is increased. Refer to the RUCKUS FastIron Campus Fabric Configuration Guide for more information.
Maximum stacking distance 10 Kilometers Refer to FastIron stacking distances and optics by device for more information.
Stacking ports Four 10-Gbps stacking ports (from eight available ports) on fixed module on front panel Module 2 on the front panel contains four stacking ports and four uplink ports, which can be used as alternative ports for stacking. Refer to ICX 7250 stacking topologies for module and port locations.
Valid-stack-port sets

Factory set (x/2/1, x/2/3, 2) or (x/2/5, x/2/7, 2)

Note: The third number in each set is the maximum number of ports in a stacking trunk.

Refer to the definition of valid-stack-port set in Stacking terminology and Valid-stack-port sets for more information.

Refer to ICX 7250 stacking topologies for port locations.

Reconfigurable ports Supported

Use the stack-port command to reconfigure one stack port as a data uplink port.

Once licensed, stacking ports come up as 10-Gbps ports automatically.

You can manually reconfigure 1-Gbps ports to 10-Gbps ports when licensed using the speed-duplex command.

Stack trunks

stack-trunk 1/2/1 to 1/2/2

stack-trunk 1/2/3 to 1/2/4

stack-trunk 1/2/5 to 1/26

stack-trunk 1/2/7 to 1/2/8

Refer to ICX 7250 trunk configuration.
Linear-topology trunks stack-trunk x/2/1 to x/2/4 or stack-trunk x/2/5 to x/2/8

Refer to Support for two-unit stack linear-topology trunks for more information.

Hitless switchover and hitless failover Supported Refer to Hitless stacking.
License requirements A license is required for 10-Gbps ports. (Trunks cannot be formed with the pre-installed two-port license.) The pre-installed license is for two 10-Gbps ports (supports stacking ports 1/2/1 and 1/2/3). Licenses are available for eight 10-Gbps ports. Refer to the RUCKUS FastIron Software Licensing Guide for information.
Configuration options Manual and automatic, including stack interactive-setup and stack zero-touch provisioning Refer to 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 RUCKUS FastIron Software Upgrade Guide for more information.
Stacking commands All stacking CLI is available on ICX 7250 devices unless otherwise noted on the command reference page.

  2. ICX 7250 Stacking Configuration Notes
  3. Reconfiguring ICX 7250 1-Gbps Ports as 10-Gbps Ports
    A port previously configured as a 1-Gbps port must be reconfigured to operate at 10 Gbps. Stacking on the ICX 7250 is only available on 10-Gbps ports in module 2.

  5. Displaying basic information for an ICX 7250 stack
  6. Displaying detailed information for an ICX 7250 stack
    Use the show stack detail command to display information on all units in the stack, including their role, MAC address, priority, status, and stack connections.
