Summit switches exchange information using EDP across Virtual Chassis links. The 
information exchanged allows the switches to automatically join VLANs. A VLAN is 
automatically joined between Summit switches that are members of the same Virtual 
Chassis stack if the VLAN name and configured 802.1Q tag values are identical.
The VLAN default is joined by all Summit switches that are connected to a 
Summit Virtual Chassis stack. This is because the VLAN name default exists on 
all Summits, and the explicit 802.1Q tag value is 1 on each switch.
