Cloud Stacking Mode Select

In Nebula 18.00, we've introduced enhancements to the switch stacking capabilities, specifically focusing on the XGS 2220. This article will guide you through the new features related to stacking mode selection and provide important operational details.

Overview of Stacking Modes

We support two primary types of stacking modes for switches:

• Two-Port Stacking: Utilizes one stacking port as active and the other as backup. This mode is more basic and aggregate multiple stacking ports for higher transmission speed.
• Four-Port Stacking: Allows two ports to be active with link aggregation, providing higher slot-to-slot throughput, while the other two ports are in backup status.

Stacking Mode Selection

Supported Models and Firmware

The new stacking mode selection feature is available on:

• XGS 2220: Requires firmware version 4.80 patch 4 or later.
• Future Models: Support will depend on future firmware updates.

Selecting Stacking Mode

Users can choose between two-port and four-port stacking modes based on their network requirements:

• Two-Port Stacking Mode: Ideal if you need the last two fiber ports for additional switching capacity.
• Four-Port Stacking Mode: Optimal for maximizing slot-to-slot throughput.

Steps to Select Stacking Mode

1. Navigate to Stacking Management: Access this through the device configuration under the "Switches" section.
2. Create a New Stack: Start the stacking setup wizard.
3. Select Stacking Mode: During the "Add Slot" step, choose between two-port or four-port stacking if using an XGS 2220 switch with the appropriate firmware.

Default Settings

• Default Mode for XGS 2220: Two-port stacking.
• Switch to Four-Port Stacking: Ensure you manually select this mode to maximize throughput.

Operational Considerations

Switching Between Stacking Modes

If you need to change the stacking mode from four-port to two-port or vice versa, the following steps are required:

• Remove Stacking Profile: This action will reset all devices in the stack to standalone cloud management mode.
• Reconfigure Settings: Returning to standalone mode resets all cloud settings to default, requiring a full reconfiguration of the stack and switch settings.

Important Reminders

• Reconfiguration Required: Switching stacking modes necessitates a complete reconfiguration of all network settings.
• Plan Ahead: Ensure that the selected stacking mode aligns with long-term network needs to avoid frequent reconfigurations.

Changing Modes Example

• Scenario: A user needs to switch from four-port to two-port stacking to free up ports for other connections.
• Process: Remove the existing stacking configuration, reset devices to standalone mode, and reconfigure the stack with the new mode.

Conclusion

The stacking mode selection feature in Nebula 18.00 for XGS 2220 and future models provides greater flexibility and control over network configurations. Ensure you understand the implications of switching modes and plan your network setup accordingly to minimize disruptions.
