Usage Information
You can pre-provision a port extender stack unit using the stack unit command
in the PE configuration mode and specify the stack-unit type. Only similar types of
stack units are provisioned under a single port extender. The maximum number of
stack units allowed for provisioning is 8. In a PE stack, by default, the stack unit with
the highest MAC address is elected master; the stack unit with the second highest
MAC address is elected standby. To change the default master and standby
assignment, you can assign stack-unitpriority value. If multiple units tie for the
highest priority, the unit with the highest MAC address is elected master.
In the following example, stack-unit 0 with priority 14 is the master and stack-unit
1 with priority 13 is the standby.
NOTE: You can configure a stack-unit priority only when the unit is online.
