The stack also assigns a Stack Member-ID number to each member. This
number provides a unique reference number for switches within the stack;
it plays no part in selecting the stack master. The Stack Member-ID is the
entity used as the first digit of the three component port identifier numbers.
For example, port number 2.0.14 has the Stack Member-ID of 2.
Note
This last point is an important one to remember when using
configuration scripts. You should ensure that you modify your
configuration scripts to match any changes you have made to the
Stack Member-ID assignments.
Note
The ability to independently set both a stack member’s priority and
its ID means that the stack master does not need to have an ID of 1;
although configuration is simplified by arranging for ID 1 to be the
device with the lowest priority value - and thereby forcing it to be the
stack master. If you create a stack using new switches, the following
(simplified) process should ensure that the master member has an
ID of 1.
New switches are shipped with a Stack Member-ID of 1 and a
priority of 128. If four such switches are created as a stack, the
switch with the lowest MAC address will be selected to be the stack
master (because all priority settings are 128). The remaining three
stack member devices will then reboot and automatically be
assigned IDs values of between 2 and 4. The stack master does not
reboot and retains its Stack Member-ID of 1.
You can change the Stack Member-ID by using the stack renumber
command.
Common Stack Configuration
Once the switches have configured themselves into a VCS stack, they all
share the same configuration information and startup scripts.
Stack Management VLAN
Managing the stack is the same as managing an individual switch. You
can connect to the asynchronous console port of any stack member, or
you can set an IP address on a network VLAN (for example, VLAN1) and
use SSH or Telnet for remote access.
As the switches form themselves into a stack, each switch creates a
common stack management VLAN and a management IP address. Both
the VLAN ID and the IP address are internal entities that are used between
