Select the check box to use VLAN multiplexing to allow multiple separate
protocols to use the same PVC. Selecting this enables IEEE 802.1q. Separate
VLANs can be used to give different priorities to the traffic from different ports.

Service Category
Select UBR (unspecified bit rate) for applications that are non-time sensitive,
such as e-mail. Use it with PCR if you want to specify a maximum rate at which
the sender can send cells.

Peak Cell Rate
The Peak Cell Rate (PCR) is the maximum rate at which the sender can send
cells. PCR applies with all of the ATM traffic classes. Type a number of (ATM)
cells per second (1~255000).

Rate
The Sustained Cell Rate (SCR) sets the average cell rate (long-term) that can
be transmitted. Type the SCR, which must be less than the PCR. SCR applies
with the VBR traffic classes. Type a number of (ATM) cells per second. The
SCR must be less than the PCR.
