Online Help Version 25.7.0

Switch Engine 4000 Series hardware allows for the configuration of Universal Port Stacking Support Mode. When Stacking Support Mode is disabled, Universal Ports U1 and U2 will operate as non-stacking ports. Once stacking ports are no longer defined as stacking, then all ExtremeCloud IQ supported port configurations apply, including configuration by port type and configurations associated with ports such as Instant Port configurations.

Note

Changing the stacking support mode will require a reboot to be performed during configuration update.

To enable or disable Universal Port Stacking Support Mode:

Go to Configure > Network Policies, to edit or create a new policy.
Select Switch Template.
From the Details page, select Switching > Port/VLAN Configuration.
Select beside the Universal Ports.
Choose your Stacking Support Mode with the Toggle.
If the device is a Switch Engine 4120 series, additional channelization options appear. Select the Channelization options for both Universal Ports.

Note
The default value selected for the 4120 SKUs is 1x100G.
Select Apply.

Note
Universal Port Stacking Support Mode can also be configured at the device-level, within the Port / VLAN Configuration page. Device level configuration overrides the template configuration.
