Configuring Stacking Management
The Stacking Page allows network managers to either reset the entire stack or a specific device. Device
configuration changes that are not saved before the device is reset are not saved. If the Stacking Master is reset,
the entire stack is reset. In addition, Unit IDs can be changed on the Stacking Page.
When configuring QoS for stacking, note that stacking only uses three queues.
To configure stack control:
1. Click Mgmt. Protocols > Stacking. The Stacking Page opens:
Figure 163:Stacking Page
The Stacking Page contains the following stack configuration fields:
• Force Master — The unit is forced to be master of the stack. Note that only Unit 1 or Unit 2 can be the stack
master. Select None for the system to decide which of the two master-enabled units is the master in the
stack.
• Unit No. — Indicates the Unit ID assigned to the unit in the current stacking configuration.
• Unit No. After Reset — Indicates the Unit ID to be reassigned to the unit in the stacking configuration after
reset.
2. Select the master election method, type of ports to be used in stacking,
3. Map/assign the unit numbers.
4. Click Apply. A confirmation message displays. The stacking settings are saved and the device configuration
is updated.
5. Click Refresh. The stacking configuration is applied.
6. Click Save Config on the menu to save the changes permanently.
If a different Unit ID is selected, the device must be reset for the configuration changes to be applied.
