Description
Configure a private IP address pool for the stack.
The master switch of a stack must be configured with a private IP address pool to
ensure that it can automatically allocate an available IP address to a member switch
when the device joints the stack.
IMPORTANT:
When you configure a private IP address pool for a stack, the number of IP addresses
in the address pool needs to be equal to or greater than the number of switches to be
added to the stack. Otherwise, some switches may not be able to join the stack
automatically for lack of private IP addresses.
