If the device does not have rack, frame, or subslot information, 0 is padded in the corresponding
field.
For ATM interfaces, all fields in the access-node-id string are filled with 0s except for the
ANI_XPI and ANI_XCI fields.

Identifier description of the access node, a string not
longer than 50 characters without spaces.
Frame number of the access node, in the range of 0 to 31.
Slot number of the access node, in the range of 0 to 127.
Subslot number of the access node, in the range of 0 to
31.
Port number of the access node, in the range of 0 to 255.
Optional.
This field is mainly used to carry CPE-side service
information, identifying the further service type
requirement. For example, use this field to identify specific
services in a multi-PVC scenario.
For ATM interfaces:
•
ANI_XPI is VPI in the range of 0 to 255.
•
ANI_XCI is VCI in the range of 0 to 65535.
For Ethernet interfaces or Ethernet trunk interfaces:
•
ANI_XPI is PVLAN in the range of 0 to 4095. This
field is set to 4096 if there is no PVLAN.
•
ANI_XCI is CVLAN in the range of 0 to 4095. This
field is set to 4096 if the user is not assigned to a
VLAN as in the situation where the end user device
is directly connected to a BRAS port.
Description
The subscriber interface is an ATM interface.
The slot number is 31, the BRAS subslot number is 31, the BRAS
port number is 7, the VPI is 255, and the VCI is 65535.
The subscriber interface is an Ethernet interface.
The slot number is 31, the subslot number is 31, the port number
is 7, the PVLAN is 1234, and the CVLAN is 2345.
If there is no PVLAN, 1234 will be replaced with 4096.
The subscriber interface is an Ethernet interface. The slot number
is 31, the subslot number is 31, the port number is 7, and the
VLAN ID is 2345.
The access node identifier of the DSLAM is guangzhou001, the
rack number is 1, the frame number is 31, the slot number is 63,
subslot number is 31, and the port number is 127.
The 0 and 0/0/0 strings indicate that BRAS does not have access
line information and will use the information received from the
access node.
After receiving access line information from the access node, the
BRAS transparently delivers the information or complements the
BRAS access link information as configured. For example, the
BRAS complements the access line information as eth
31/31/7:4096.1234 guangzhou001/0/31/63/31/127.
