Dedicated Port Stacking

This section describes the commands you use to configure dedicated port stacking.

stack

This command sets the mode to Stack Global Config.

• Format: stack
• Mode: Global Config

member

This command configures a switch. The <unit> is the switch identifier of the switch to be added/removed from the stack. The <switchindex> is the index into the database of the supported switch types, indicating the type of the switch being preconfigured. The switch index is a 32-bit integer. This command is executed on the Primary Management Unit.

• Format: member <unit> <switchindex>
• Mode: Stack Global Config

NOTE: Switch index can be obtained by executing the show supported switchtype command in User EXEC mode.

no member

This command removes a switch from the stack. The <unit> is the switch identifier of the switch to be removed from the stack. This command is executed on the Primary Management Unit.

• Format: no member <unit>
• Mode: Stack Global Config

switch priority

This command configures the ability of a switch to become the Primary Management Unit. The <unit> is the switch identifier. The <value>is the preference parameter that allows the user to specify, priority of one backup switch over another. The range for priority is 1 to 15. The switch with the highest priority value will be chosen to become the Primary Management Unit if the active Primary Management Unit fails. The switch priority defaults to the hardware management preference value 1. Switches that do not have the hardware capability to become the Primary Management Unit are not eligible for management.

• Default: enabled
• Format: switch <unit> priority <value>
• Mode: Global Config

switch renumber

This command changes the switch identifier for a switch in the stack. The <oldunit> is the current switch identifier on the switch whose identifier is to be changed. The <newunit> is the updated value of the switch identifier. Upon execution, the switch will be configured with the configuration information for the new switch, if any. The old switch configuration information will be retained, however the old switch will be operationally unplugged. This command is executed on the Primary Management Unit.

NOTE: If the management unit is renumbered, then the running configuration is no longer applied (i.e. the stack acts as if the configuration had been cleared).

• Format: switch oldunit renumber newunit
• Mode: Global Config

movemanagement

This command moves the Primary Management Unit functionality from one switch to another. The <fromunit>is the switch identifier on the current Primary Management Unit. The <tounit> is the switch identifier on the new Primary Management Unit. Upon execution, the entire stack (including all interfaces in the stack) is unconfigured and reconfigured with the configuration on the new Primary Management Unit. After the reload is complete, all stack management capability must be performed on the new Primary Management Unit. To preserve the current configuration across a stack move, execute the copy system:running-config nvram:startup-config (in Privileged EXEC) command before performing the stack move. A stack move causes all routes and layer 2 addresses to be lost. This command is executed on the Primary Management Unit. The system prompts you to confirm the management move.

• Format: movemanagement <fromunit> <tounit>
• Mode: Stack Global Config

standby

Use this command to configure a unit as a Standby Management Unit (STBY).

NOTE: The Standby Management Unit cannot be the current Management Unit. The Standby unit should be a management-capable unit.

• Format: standby unit number
• Mode: Stack Global Config
• Standby Management Unit: Number Indicates the unit number which is to be the Standby Management Unit. unit number must be a valid unit number.

no standby

The no form of this command allows the application to run the auto Standby Management Unit logic.

• Format: no standby
• Mode: Stack Global Config

slot

This command configures a slot in the system. The <unit/slot> is the slot identifier of the slot. The <cardindex> is the index into the database of the supported card types, indicating the type of the card being preconfigured in the specified slot. The card index is a 32-bit integer. If a card is currently present in the slot that is unconfigured, the configured information will be deleted and the slot will be re-configured with default information for the card.

• Format: slot <unit/slot> <cardindex>
• Mode: Global Config

NOTE: Card index can be obtained by executing show supported cardtype command in User EXEC mode.

no slot

This command removes configured information from an existing slot in the system.

• Format: no slot <unit/slot> <cardindex>
• Mode: Global Config

NOTE: Card index can be obtained by executing show supported cardtype command in User EXEC mode.

set slot disable

This command configures the administrative mode of the slot(s). If you specify [all], the command is applied to all slots, otherwise the command is applied to the slot identified by <unit/slot>.

If a card or other module is present in the slot, this administrative mode will effectively be applied to the contents of the slot. If the slot is empty, this administrative mode will be applied to any module that is inserted into the slot. If a card is disabled, all the ports on the device are operationally disabled and shown as "unplugged" on management screens.

• Format: set slot disable [<unit/slot>] | all]
• Mode: Global Config

no set slot disable

This command unconfigures the administrative mode of the slot(s). If you specify all, the command removes the configuration from all slots, otherwise the configuration is removed from the slot identified by <unit/slot>.

If a card or other module is present in the slot, this administrative mode removes the configuration from the contents of the slot. If the slot is empty, this administrative mode removes the configuration from any module inserted into the slot. If a card is disabled, all the ports on the device are operationally disabled and shown as "unplugged" on management screens.

• Format: no set slot disable [<unit/slot>] | all]
• Mode: Global Config

set slot power

This command configures the power mode of the slot(s) and allows power to be supplied to a card located in the slot. If you specify all, the command is applied to all slots, otherwise the command is applied to the slot identified by <unit/slot>.

Use this command when installing or removing cards. If a card or other module is present in this slot, the power mode is applied to the contents of the slot. If the slot is empty, the power mode is applied to any card inserted into the slot.

• Format: set slot power [<unit/slot>] | all]
• Mode: Global Config

no set slot power

This command unconfigures the power mode of the slot(s) and prohibits power from being supplied to a card located in the slot. If you specify all, the command prohibits power to all slots, otherwise the command prohibits power to the slot identified by <unit/slot>.

Use this command when installing or removing cards. If a card or other module is present in this slot, power is prohibited to the contents of the slot. If the slot is empty, power is prohibited to any card inserted into the slot.

• Format: no set slot power [<unit/slot>] | all]
• Mode: Global Config

reload (Stack)

This command resets the entire stack or the identified <unit>. The <unit> is the switch identifier. The system prompts you to confirm that you want to reset the switch.

• Format: reload [<unit>]
• Mode: Global Config
