Table 9-3. Stacking Configuration Guide
The easiest way to
automatically
create a stack is to:
1.
Configure a switch as a Commander.
2.
Configure IP addressing and a stack name on the Commander.
3.
Set the Commander’s
Auto Grab
parameter to
Yes
.
4.
Connect Candidate switches (in their factory default configuration) to
the network.
This approach automatically creates a stack of up to 16 switches (including
the Commander). However this replaces manual control with an automatic
process that may bring switches into the stack that you did not intend to
include. With the Commander’s
Auto Grab
parameter set to
Yes
,
any switch
conforming to all four of the following factors automatically becomes a stack
Member:
■
Default stacking configuration (
Stack State
set to
Candidate
, and
Auto Join
set to
Yes
)
■
Same subnet (broadcast domain) and default VLAN as the
Commander (If VLANs are used in the stack environment, see
“Stacking Operation with a Tagged VLAN” on page 9-44.)
■
No Manager password
■
14 or fewer stack members at the moment
