*The Commander’s Manager and Operator passwords propagate to the candidate when it joins the stack.

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 9-47.)

■No Manager password

■14 or fewer stack members at the moment
