• after - Schedule reloading after certain time period
• at - Schedule reloading at an exact later time
• cancel - Cancel scheduled reload
• unit-id - Stack members to reload. The unit-list variable can be a combination, such as 2,4-6,8.
Tokens must be separated by a comma and there is no space.
Stack units can be reloaded only if they are not the active master. To reload the active master, use the
stack switch-over command. When hitless failover is enabled, reloading the active master happens
automatically.
When switchover occurs, the old mater unit can be reloaded using the reload unit command.
Controlling stack topology
Because Stackable devices allow you to use one of the two ports intended for stacking as a regular
data port, you can control the size of your stack. The following example shows a stack where the
existing ring topology is changed so that only one unit in the upstream direction is connected through a
stacking port, which limits the size of the stack to two units.

Managing traditional stack partitioning
When a unit in a traditional stack with a linear topology fails, the traditional stack divides (partitions)
into two or more separate stacks that all have the same configuration. This may cause an IP address
conflict in the network. If you want to keep the stacks separate, you will need to change the IP address
of each new stack.
