  4. Verify System and Stack-Port Status
  5. Reset a Switch Removed from Stack to Default

 

Important Points to Remember

 

  • S55 can have up to 8 units in a stack
  • The S55 and S60 systems DO NOT SUPPORT mixed stacking.  Stack only S55 systems together.
  • The S55 only has 12g stacking option.  24g ports or cables are not available.

 

Needed Hardware

 

Stacking Modules
 

- not interchangeable

- Types

12 Gigabit  - 2 port

 

Cables

- bi-directional

- length

4 meters

60 centimeters

Creating a Stack

 

Command

Purpose

FTOS# show version

Verify that each unit has the same FTOS version prior to stacking them together.

FTOS# stack-unit renumber

Pre-configure unit numbers for each unit so that the stacking is deterministic upon boot up. (Optional)

FTOS(config)# stack-unit priority

Configure the switch priority for each unit to make management unit selection deterministic.  Highest number represents the higher priority.  (Optional)

Connect the units using stacking cables and modules

Power the stack one unit at a time.  Start with the management unit, then the standby, followed by each of the members in order of their assigned stack number (or the position in the stack you want each unit to take).  Allow each unit to completely boot, and verify that the unit is detected by the stack manager, and then power on the next unit.

FTOS# show system brief

Verifies the stack status of the units.

 

 

NOTE:  A reload of all switch units is needed for stack unit renumbering. Newly installed stack modules are not recognized by the switch until the switch is reloaded.

 

Verify System and Stack-Port Status

Reset a Switch Removed from Stack to Default

 

The running-configuration and startup-configuration are synchronized on all stack units. A stack member that is disconnected from the stack maintain this configuration.

To remove a stack member from the stack, disconnect the stacking cables from the unit. You may do this at any time, whether the unit is powered or unpowered, online or offline.

The stack continues to use the primary switch chassis MAC address even after a failover. The MAC address is not refreshed until the stack is reloaded and a different unit becomes the stack manager.

 

 

NOTE:  If the removed management unit is brought up as a standalone unit or as part of a different stack, there is a possibility of MAC address collisions until the original stack is reloaded.

  

NOTE:  If you remove a unit in the middle of the stack, the stack will be split into multiple parts, and each will form a new stack according to the stacking algorithm.

 

 

Command

Purpose

FTOS# reset stack-unit 0-11

Reload a stack-unit.

FTOS# reset-self

Reload a member unit, from the unit itself.

FTOS# reset stack-unit 0-11 hard

Reset a stack-unit when the unit is in a problem state.
