show stacking configuration

show stacking configuration

Description

Shows how the nodes are configured in a stack topology. The configured values shown are the ones actually stored in the remote nodes at the time you issue this command.

Syntax Description

This command has no arguments or variables.

Default

N/A.

Usage Guidelines

Some stacking parameters do not take effect until the next restart, the configured values and the values currently being used are both shown. Specifically, this applies to the slot number, whether or not stacking is enabled, the master-capable configuration, the license level restriction, and the stack MAC configuration.

The only parameters that take effect without a reboot are the node priority and the alternate management IP subnetwork and gateway.

The Stack MAC in use line can display the following values:
  • If the command is executed on the master node:
    • none if there is no stack MAC configured.

    • The stack MAC configured on the master node.

  • If the command is executed on a non-master node:
    • unknown. The stack MAC address is only known by the executing master node. In this case, the M and m flags are not set. The i flag is set if there is a stack MAC configured locally.

Identified with the asterisk, the current node is the one on which the show stacking configuration command is executed.

A node identified with the ? character indicates that timely attempts to fetch the configuration information from the node have failed. There are two possible reasons for this display:
  • Communications with the node have been lost, in which case the node will probably be removed from the stack topology shortly.

  • The node is too busy to respond in time.

A row that displays the ? indicator shows the last values that were received from the node. If no values were ever received, all configured values show as not configured (-) or none. The node MAC address and the slot number that is currently in use are still displayed.

Example

The following example:

Slot-1 Stack.2 # show stacking configuration
