semicolon are two zre_lists separated by an equal sign. The first is the list of virtual port
names, the second is the physical port names. The assignment is done in order, and there must be
an equal number of ports in each list. Wild cards may be used in the zre_lists. See below.
Stack port association syntax for a base switch:
stack0: zre0..11 = zre0..11;
stack1: zre12..23 = zre0..11;
The first statement above configures the first switch silicon chip, represented by stack0, to have
no translation between its physical port numbering and its virtual port numbering.
NOTE: The statement must be made even if the mapping is one to one.
The second statement above configures the second switch silicon chip to have its physical ports 0
through 11 map to virtual ports 12 through 23. The mapping is done in a linear fashion. zre0
maps to zre12. zre1 maps to zre1 and so on.
Stack Configuration Statements
After stack creation and port association, the configuration of the stack must be defined. The
stack configuration provides the network map of how inter-switch fabric communication is
performed. It specifies which physical port or should be used to communicate with a different
group of stacked ports. The syntax is as follows:
stack<N>: stack<M> = zre<n>;
The above syntax indicates that stack N should use zre n to access stack M. The zre value n is
a physical port number as seen by Stack N. It is not a virtual port number as mapped by a port
association command. Multiple configuration statements for Stack N can be used to indicate how
to get to other stacks.
NOTE: stack<M> can be a list of comma delimited or range of stacks as described below
in the section on wild cards.
Stack port association example for a base switch:
stack0: stack1 = zre12;
stack1: stack0 = zre12;
The above example indicates that stack0 is connected to stack1 through the port 12 and stack1 is
connected to stack0 through port 12. Zre12 on the base switch switch fabric chips is the HIGIG
port and are directly connected between the two devices.
