CHAPTER 66
Virtual Channel Commands
This chapter shows you how to use commands to configure virtual channels.
See Chapter 16 on page 119 for background information on virtual channels and
ATM QoS.
66.1 Virtual Channel Command Input Values
The following table describes the values required in Virtual Channel commands.
Other values are discussed with the corresponding commands.
Table 194 Virtual Channel Command Input Values
LABEL DESCRIPTION
cdvt Cell Delay Variation Tolerance (CDVT) is the accepted tolerance of the
difference between a cell’s transfer delay and the expected transfer
delay (measured in number of cells). Possible values are 0~255 or *
(means 0).
member-vci The VCI of the individual PVC that you are adding to a Permanent
Virtual Circuit (PVC). The subscriber’s device must create this PVC.
member-vpi The VPI of the individual PVC that you are adding to a PPVC. The
subscriber’s device must create this PVC.
pcr The Peak Cell Rate (150~300 000) is the maximum rate (measured in
cells per second) at which the sender can send cells.
portlist You can specify a single ADSL port <1>, all ADSL ports <*> or a list
of ADSL ports <1,3,5>. You can also include a range of ports
<1,5,6~10>.
priority The priority level (0~7) assigned to PVC traffic. 7 is the highest
priority.
vc|llc The type of encapsulation.
VC Mux is a type of encapsulation where, by prior agreement, each
protocol is assigned to a specific virtual circuit, for example, VC1
carries IP and VC2 carries IPX.
LLC is a type of encapsulation where one VC carries multiple protocols
with each packet header containing protocol identifying information.
vcprofile, ds-
vcprofile, us-
vcprofile
The name of the virtual channel profile (up to 31 ASCII characters).
You can assign profiles for downstream and upstream virtual
channels. You cannot change the DEFVAL or DEFVAL_VC profiles.
