ICX 7250 stack configuration overview
The following table provides an overview of ICX 7250 stacking capabilities.
Stacking capability | ICX 7250 | Additional information |
---|---|---|
Topologies supported | Ring and linear | Refer to ICX 7250 stacking topologies. |
Maximum stack size | 12 | Traditional stacking only. Any combination of stackable ICX 7250 devices may be stacked. |
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 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. |
Default ports |
Two ports: 1/2/1 and 1/2/3 NOTE Default stacking ports can be changed to 1/2/5 and 1/2/7. Use the
default-ports
command to change the default ports.
|
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. Use the default-ports command to move stacking ports. 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. Refer to Traditional stack CLI commands . |
Stack trunks | Supported | Refer to ICX 7250 trunk configuration. |
Hitless switchover and hitless failover | Supported | Refer to Hitless stacking. |
License requirements | A POD 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 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 | All stacking CLI is available on the ICX 7250 unless otherwise noted on the command reference page. | Refer to Traditional stack CLI commands . |
