VLAN 1.

Usage Information
• To verify the currently congured mode on a Fabric Engine, enter the show operating mode command. If
a Fabric Engine is in Full Switch mode, you must manually provision a Fabric Expander using the unit-

trac, you must congure the virtual port on the Fabric Expander by entering the unit ID as the virtual-slot
number in the interface ethernet node/virtual-slot/port command.
