Source VLAN type:
Dest VLAN type:
VLAN (Source)
The VLAN number to assign to the source port. You can allow the system to assign a VLAN for you by selecting the Auto-assign VLAN checkbox. You may alternatively request a specific VLAN number (i.e. 3000) or provide a range in which one may be chosen (i.e. 3000-4000)
VLAN (Dest)
The VLAN number to assign to the destination port. If the Same VLAN on source and destination box is selected then this will be given the same limits as the VLAN (Source) field. If a different VLAN is selected then VLAN translation will occur between the source and destination.
Source VLAN type
If 'Tagged' is chosen then only data marked with the source VLAN number in the 802.1Q headers will be able to use the circuit. If 'Untagged' then all unmarked packets will be allowed. If 'Untagged' is chosen then no other circuits can be built on the source port until the reservation ends.
Dest VLAN type
The same as Source VLAN type except applied to the destination port.
