Discovery of Newly Installed Switches
To join a cluster, the new, out-of-the-box switch must be connected to the cluster through one of its access ports. An
access port (AP) carries the traffic of and belongs to only one VLAN. By default, the new switch and its access ports are
assigned to VLAN 1.
When the new switch joins a cluster, its default VLAN changes to the VLAN of the immediately upstream neighbor. The
new switch also configures its access port to belong to the VLAN of the immediately upstream neighbor.
