RUCKUS ICX switches support stacking over both copper and fiber connections, allowing for flexible deployment across various distances:

Copper Stacking Cables:

Maximum Distance:

Up to 5 meters using active direct-attach copper (DAC) cables.

Use Case:

Suitable for stacking switches within the same rack or in close proximity.

Fiber-Optic Stacking Cables:

Maximum Distance:

Up to 40 kilometers using appropriate optical transceivers and single-mode fiber.

Use Case:

Ideal for stacking switches located in different buildings or across a campus environment.

References:

For detailed information on stacking distances and supported optics, refer to the FastIron stacking distances and optics guide: FastIron stacking distances and optics by device

By utilizing fiber-optic connections with appropriate transceivers, ICX switches can be stacked over substantial distances, providing flexibility in network design and deployment.

Power over Ethernet (PoE) allows ICX switches to deliver electrical power to connected devices over standard Ethernet cables. The amount of power provided is determined by the PoE class assigned to the port. To supply a maximum of 15.4W to a connected device, the port should be configured to PoE Class 3.

PoE Power Classes:

Class 0: 0.44W to 12.95W

Class 1: 0.44W to 3.84W

Class 2: 3.84W to 6.49W

Class 3: 6.49W to 15.4W

Class 4: 15.4W to 30W (PoE+)

Configuration Steps:

Access the Switch's CLI:

Connect to the switch via console or SSH to access the Command Line Interface (CLI).

Enter Global Configuration Mode:

enable

configure terminal

Navigate to the Specific Interface:

Replace 1/1/1 with the appropriate interface identifier.

interface ethernet 1/1/1

Set the PoE Power Class:

Configure the port to provide power corresponding to Class 3.

inline power power-by-class 3

Exit Configuration Mode and Save Changes:

end

write memory

Verification:

Check PoE Status:

To verify the PoE status and power allocation on the configured port, use:

show inline power

This command displays the current PoE status, power consumption, and class information for each port.

Considerations:

Device Compatibility:

Ensure that the connected device is compatible with PoE Class 3 and does not require more than 15.4W.

Power Budget:

Monitor the switch's total PoE power budget to prevent over-subscription when multiple devices are connected.

When a high CPU utilization alert is triggered on a RUCKUS ICX switch, it's essential to identify the processes consuming excessive CPU resources. The show cpu tasks command provides detailed information about active processes and their CPU usage.

Command Usage:

show cpu tasks

Output Example:

Task Name CPU Time (ms) Invocations Avg Time (us)

------------------ -------------- ------------ -------------

TaskA 5000 1000 5000

TaskB 3000 1500 2000

In this output:

Task Name lists the names of active processes.

CPU Time (ms) indicates the total CPU time consumed by each process in milliseconds.

Invocations shows how many times each process has been called.

Avg Time (us) represents the average time per invocation in microseconds.

By analyzing this data, administrators can pinpoint processes that are utilizing disproportionate CPU resources, facilitating targeted troubleshooting and optimization.
