ICX 7850 Stack Configuration Overview
ICX 7850 Stacking Capability
| Stacking Capability | ICX 7850 | Additional Information |
|---|---|---|
| Topologies supported | Ring and linear | Refer to ICX 7850 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 7850 model combinations | Allowed (all models) | ICX 7850-48F, ICX 7850-48FS, and ICX 7850-32Q models can be combined in the same stack. |
| Stacking ports | 8 X 100 Gbps or 8 X 40 Gbps ICX 7850-32Q: ports 1/3/1 to 1/3/8 ICX 7850-48FS/48F: ports 1/2/1 to 1/2/8 |
Stacking port speeds are auto-detect. |
| Valid-stack-port sets | ICX 7850-32Q: (x/3/1, x/3/5, 4) ICX 7850-48FS/48F: (x/2/1, x/2/5, 4)
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 7850 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 | The following maximum stacking trunk configurations are supported: ICX 7850-32Q: stack-trunk 1/3/1 to 1/3/4 or stack-trunk 1/3/5 to 1/3/8 ICX 7850-48FS/48F: stack-trunk 1/2/1 to 1/2/4 or 1/2/5 to 1/2/8 |
See also "Linear-topology trunks" in this table. |
| Linear-topology trunks | The following maximum linear-topology trunks are supported:
ICX 7850-32Q: stack-trunk x/3/1 to x/3/8 ICX 7850-48FS/48F: stack-trunk x/2/1 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 | No license required for
stack-port configuration. No license required for Premium features.
|
For more information on ICX 7850 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 CLI is supported on ICX 7850 devices unless otherwise stated on the command reference page. |
