In this stack, the only SNs in use are 0 and 1,
so you can use any SN number from 2 through
15 for new Members. (The SN of "0" is always
reserved for the stack Commander.)

Using the Commander's CLI To Manually Add a Candidate to the
Stack. To manually add a candidate, you will use:
■ A switch number (SN) to assign to the new member. Member SNs range
from 1 to 15. To see which SNs are already assigned to Members, use show
stack view. You can use any SN not included in the listing. (SNs are
viewable only on a Commander switch.)
The MAC address of the discovered Candidate you are adding to the stack.
■
To see this data, use the show stack candidates listing .
For example:
To display all discovered Candidates with their MAC addresses, execute show
stack candidates from the Commander's CLI. For example, to list the discov­
ered candidates for the above Commander:
Knowing the available switch numbers (SNs) and Candidate MAC addresses,
you can proceed to manually assign a Candidate to be a Member of the stack:
Syntax:
stack member < switch-number > mac-address < mac-addr >
[ password < password-str > ]
Stack Management for the Series 3400cl and 6400cl Switches
Note: When manually adding a switch, you must assign an SN.
However, if the Commander automatically adds a new Member,
it assigns an SN from the available pool of unused SNs.
