Performing Software Configurations
Context
After you install a stack card and power on the switch, you can configure related software on the switch. Available configuration options include configuring a stack ID, and configuring a stack priority. By default, the stacking function is enabled on a switch, and you are advised to configure a stack ID and a stack priority to facilitate management. You can configure stack software on a switch that uses stack card stacking with stack ports fixed on the rear panel after the switch is powered on, without having to install stack cards on the switch.
Stack IDs identify member switches in a
stack. Each stack member switch has a unique stack ID. If a new member
switch has the same stack ID as an existing member switch, the master
switch assigns another stack ID to the new member switch. You can
also configure a stack ID for this member switch. To facilitate management
on switches, you are advised to plan and configure stack IDs for member
switches before setting up a stack. A member switch's stack ID affects
many configurations on the switch, for example, port numbers (physical
and logical ports) and port configurations. Pay attention to the following
points when configuring stack IDs for member switches:
- If you do not restart a switch after changing its stack ID, the new stack ID will not take effect. That is, the switch still uses the original stack ID, and all physical resources are identified by the original stack ID.
- If you save the current configuration and restart the switch after changing its stack ID, the new stack ID takes effect and all the physical resources are identified by the new stack ID. In the configuration file, only the global stack configuration and stack priority of the switch are still in effect. All the other configurations (such as port configuration) related to the original stack ID do not take effect and must be reconfigured.
Procedure
- Run the system-view command to enter the system view.
- (Optional) Run the stack slot slot-id renumber new-slot-id command to configure a stack ID for
the switch.
By default, the stack ID of a switch is 0.
The configuration takes effect after the switch is restarted.
- (Optional) Run the stack slot slot-id priority priority command to configure a stack priority
for the switch.
By default, the stack priority of a member switch is 100.
- (Optional) Run the display stack configuration [ slot slot-id ] command to check the stack configuration on a member switch.
