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. (Optional) |
Connect the units using stacking cables and modules |
|
FTOS# show system brief |
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. |
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.
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. |
