55.2 Virtual Channel Profile Commands

Use the following commands to configure virtual channel profiles.

vlan-id This is the VLAN Identifier (1 – 4094) added to routed Ethernet frames. Each

PVC must have a unique vlan-id since the IES-612-51 forwards traffic back to

the subscribers based on the VLAN ID.

vpi, vci The Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI) identify a

channel on this port.

Possible values for the VPI are 0~255. This PVC channel is for internal use. The

subscriber does not need to create this PVC.

Possible values for the VCI are 32~65535 if the VPI is 0. If the VPI is not 0,

possible values for the VCI are 1~65535. This PVC channel is for internal use.

The subscriber does not need to create this PVC.

Table 143 Virtual Channel Profile Commands

COMMAND DESCRIPTION P

adsl vcprofile show

[vcprofile]

Displays the settings of the specified virtual channel profile (or all of them if

you do not specify one).

L/L

adsl vcprofile set

<vc|llc><ubr|cbr><pcr>

<cdvt>

Creates a virtual channel profile.

ubr|cbr: Specify either a unspecified bit rate (UBR) or constant bit rate

(CBR).

H/H

adsl vcprofile set

<vc|llc><vbr(rt-

vbr)|nrt-vbr>

Creates a virtual channel profile. After you create a virtual channel profile,

you can assign it to any of the ADSL ports on any of the ADSL IES-612-51

in the IES-612-51.

vbr(rt-vbr)|nrt-vbr: The Real-Time Variable Bit Rate (RT-VBR) or

Non Real-Time (NRT-VBR) Variable Bit Rate ATM traffic class.

pcr: Peak Cell Rate (PCR) is the maximum rate (150 to 300000 cells per

second) at which the sender can send cells.

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. Enter from 0 to 255 or * (means 0).

scr: The Sustained Cell Rate (SCR) sets the average cell rate (long-term)

that can be transmitted (measured in cells per second). SCR applies to the

VBR traffic class.

bt: Burst Tolerance (BT) is the maximum number of cells that the port is

guaranteed to handle without any discards (number of cells). BT applies to

the VBR traffic class.

H/H

adsl vcprofile delete

You cannot delete a virtual channel profile that is assigned to any of the

ADSL ports. Assign a different profile to any ADSL ports that are using the

profile that you want to delete, and then you can delete the profile.
