basinfo-insert

Function

The basinfo-insert cn-telecom command configures the device to insert the access-line-id information in the format defined by cn-telecom if the device does not trust the access-line-id information sent from the DHCP client.

The undo basinfo-insert cn-telecom command configures the device not to trust the access-line-id information sent from the DHCP client.

The basinfo-insert version2 command configures the device to insert the access-line-id information in the format defined by version2 if the device does not trust the access-line-id information sent from the DHCP client.

The undo basinfo-insert version2 command restores the default setting.

By default, the device does not trust the access-line-id information sent from a DHCP client or insert BAS information in the format defined by cn-telecom or version2 before the access-line-id information.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

After the basinfo-insert cn-telecom or basinfo-insert version2 command is configured, the device untrusts the access-line-id field or the PPPoE+ field contained in the DHCP sent by a client. Instead, the device creates an access-line-id field based on the physical location of the user that is determined through the user information such as the VLAN, and then inserts the access-line-id to the message before sending the message to the DHCP server, or RADIUS server.

If basinfo-insert cn-telecom is set, the device will insert the BAS information in the format defined by cn-telecom in one of the following formats:

BAS information in the format defined by cn-telecom + 0/0/0/0/0/0

Encapsulation format on a GE interface: <slot>/<subslot>/<port>/:<outer vlan>.<inner vlan>
Encapsulation format on a trunk interface: <slot>/<subslot>/<port>/:<outer vlan>.<inner vlan>
For example, eth 0/1/13:4096.4 0/0/0/0/0/0
If basinfo-insert version2 is set, the device will insert the BAS information in the format defined by version2 in one of the following formats:
Encapsulation format on a GE interface:<BNG-Hostname> eth <0>/<slot>/<subslot>/<port>:<outer vlan>.<inner vlan>
For example, huawei eth 0/0/1/1:50.60
Encapsulation format on a trunk interface:<BNG-Hostname> trunk <0>/<0>/<slot>/<trunkid>:<outer vlan>.<inner vlan>
For example, huawei trunk 0/0/2/11:200.100

Prerequisites

Before running this command, set the access type of the user by the access-type command.

Precautions

This command is supported only on the admin VS.

The basinfo-insert cn-telecom command is mutually exclusive with the following commands:

client-option82 basinfo-insert cn-telecom
access-line-id basinfo-insert cn-telecom
client-option82 version1
basinfo-insert version2

Example

# Configure the BAS interface GE 0/1/0 to untrust the DHCP access-line-id field reported by a client and insert the access-line-id information in the format defined by cn-telecom.
