Configuring Slot Numbers

When you configure a stack manually, each node in the stack must be assigned a unique slot number. You can assign the slot number only through configuration; the stack does not dynamically assign a slot number. The available slot numbers are 1 through 8. You can specify a slot number for each node manually, or you can have the system assign the slot numbers using a single command.

Note

Slot numbers take effect only after a restart. If you change a slot number, the unit continues to operate with the slot number it was last restarted with.

To manually add a slot number to a node, use the following command:
configure stacking node-address mac_address slot-number slot_number
where mac_address is the node's MAC address.
To configure the system to choose slot numbers for all nodes, enter the command:
configure stacking slot-number automatic

Automatic slot number assignment is performed in the order of appearance of the nodes in the show stacking display. In the case of a ring topology, the first node in the display is the intended master node into which you have logged in.
To view current slot number assignments, regardless of whether they were assigned manually or automatically, use either the show stacking or the show stacking configuration command.
You can find examples of these commands and their output in Verifying the Configuration.
Note
A node that boots in standalone mode does not use a slot number.
