configure stacking node-address

configure stacking node-address node_address slot-number slot_number


Configures a slot number on one or all nodes in the stack topology.

Syntax Description


Specifies the MAC address of a node in the stack. To view the MAC addresses for all nodes in a stack, enter the show stacking command.


Specifies a number between 1 and 8 that is to be assigned as the slot number of the target node.


The default slot-number for a node in stacking mode is 1.

Usage Guidelines

The configuration is stored on the affected node(s) immediately but does not take effect until the next reboot of the node(s). The configuration applies only when the node is running in stacking mode. To see the configured and active slot numbers of all nodes, use the show stacking configuration command.

If a node-address and a slot number are specified, then the node is configured with the specified slot number. There is no check for a duplicate slot number at this time; the number is simply assigned as requested.

To see the resulting slot number assignment, run the show stacking configuration command.



Failure to configure a node does not prevent configuration of the slot numbers on the other nodes, and does not affect the slot number assigned to each node.

When this command is executed successfully, the following message appears:

This command will take effect at the next reboot of the specified node(s).


To configure slot number 4 for the node with MAC address 00:04:96:26:6b:ed:

configure stacking node-address 00:04:96:26:6b:ed slot-number 4
