ICX 7550 Stack Configuration Overview

The following table provides an overview of ICX 7550 stacking capabilities.

ICX 7550 Stacking Capability

Stacking Capability ICX 7550 Additional Information
Topologies supported Ring and linear Refer to ICX 7550 stacking topologies for more information.
Maximum stack size 12 Stacking only.
Maximum stacking distance

40 kilometers

Refer to FastIron stacking distances and optics by device for more information.
ICX 7550 model combinations Allowed (all models)  
Stacking ports

100 Gbps or

2 X 40 Gbps

Stacking port speeds are auto-detect.

Not all models support 100-Gbps stacking.

Refer to ICX 7550 Stacking Configuration Notes.

Valid-stack-port sets

(x/2/1, x/2/2, 1)

Note: The third number in the set is the maximum number of ports in a stacking trunk. The number "1" indicates a single stack-port only.

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

Refer to ICX 7550 Stacking Topologies for port locations.

Reconfigurable ports Use the stack-port and stack-trunk commands to reconfigure ports. Stacking port speeds are auto-detect and cannot be configured.
Trunks

Stacking trunks are not supported in ICX 7550 stacks, with the exception of two-unit linear-topology trunks.

Refer to "Linear-topology trunks" in this table.
Linear-topology trunks The following maximum linear-topology trunks are supported in an ICX 7550 two-unit stack:

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

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 No license required for stack-port configuration. No license required for Premium features. For more information on ICX 7550 license options, refer to the RUCKUS FastIron Software Licensing Guide.
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 applications. Refer to the RUCKUS FastIron Software Upgrade Guide for more information.
Stacking commands All stacking commands are supported on ICX 7550 devices unless otherwise stated on the command reference page.
