To configure the stack mode of all units in stack after reboot, use the set stack mode Privileged EXEC mode command.

Syntax

set stack mode {native| hybrid}

Parameters

• native - all units in stack are of the same type (network interfaces type is the same on all units).

• hybrid - units in stack contain units of different types (network interfaces type of different units may be different).

Default Configuration

native mode

Command Mode

Privileged EXEC mode

User Guidelines

• command is applied to all units in stack

• After prompting user, command will reload all devices in stack.

• Reseting stack/unit to factory default will return all units to native mode (the default)

• In case of changing mode from native to hybrid mode, the command will delete stack startup configuration as well, and may upgrade inactive image version on all units to active image version (if current inactive image does not support hybrid mode) . It is advisable to save device configuration to external server before changing modes.

To configure the unit type of a stack member , use the set stack unit-type Privileged EXEC mode command.

set stack unit-type unit unit-id network network-type uplink uplink-type

Parameters

• unit unit-id - Define the unit ID to apply setting. (Range: 1–4)

• network network-type - The type of network ports of the unit. Supported values are:

  • gi (for device for which all network ports types are Gigabitethernet)

  • tw (for device for which all network ports types are TwoPointFiveGigabitEthernet).

  • te (for device for which all network ports typs are Tengigabitethernet).

• uplink uplink-type - The type of uplink ports of the unit. Supported values are:

  • te (for device with Tengigabitethernet uplink ports)

  • none (for devices with no uplink ports)

Default Configuration

User defined type is not configured

Command Mode

Privileged EXEC mode

User Guidelines

Use the set stack unit-type command to define the type of "not-present" stack units (see below). The type of unit in stack defines the type of interface naming for this unit and determines which interface level commands can be applied.

If a unit is present or inserted in a stack, the unit type is automatically set by the software to the type of unit identified. If unit that was present is subsequently removed from stack the unit will become "not-present" but retain the existing unit type. If a unit is "not-present", and there is no previous type identified (unit did not exist previously in stack), its unit type is automatically set to the same unit type as the Active unit.

• if network port type is set to te, uplink port type must be set to none.

• if network port type is set to gi or tw , uplink port type must be set to te.

• If the command is applied to a unit which is present in stack, command will fail with the following error message: "Unit ID X is present in stack - cannot manually set unit type"

• The unit-type of each unit is saved across reboots and displayed as part of configuration file header in the following format: "unit-type unit X network  network-type uplink  uplink-type"

To place the user in the context of the specified stack unit or all stack units, use the stack unit Global Configuration command.

Syntax

stack unit {unit-id | all}

Parameters

• unit-id— Select a specific unit. All commands after this command refer to this unit. Unit must be member in the stack. (Range: 1–4).

• all—Select all the units in the stack.

Default Configuration

None

Command Mode

Global Configuration mode

To configure the ports and unit id after reboot, use the stack configuration command.

Syntax

stack configuration {[links ports-list] [unit-id {unit-id | auto}] }

no stack configuration

Parameters

• links— Select port list to be used as stack links after reload.

• ports-list - a list of one or more stack ports separated by comma, or a range of sequential ports marked by dash.

  no-links— set stack unit without stack links after reboot.

• unit-id— Select the unit id to be used after reload. (Range: 1–4). Use auto to enable stack auto numbering feature.

Command Mode

Global Configuration mode

Stack Unit mode.

User Guidelines

• Running the command in Global Configuration mode will configure the current stack Active unit.

• The no stack configuration is used to return the stack configuration to factory default after reload (use the reload command to reboot unit).

• Running the command in stack unit all context and configuration of the unit-id parameter not to auto generate an error (to avoid setting several units to the same Id).

• Optional parameters not provided in the command will not be changed.

To display the stack configuration (including configuration that is configured after reboot) parameters, use the show stack configuration EXEC mode command.
