Displaying General or Detailed Information about Stack Members
You can display information about any member in
a stack by entering show commands from the active controller console port. If you enter
show commands
from a unit that is not the active controller, the information may not be displayed
correctly.
The
show stack command displays general information about a stack, for all members, for a specified
member, or for all members with additional detail.
The following output covers the entire stack and includes role history for each unit, beginning with the initial role the unit held.
