calling-number-avp

Function

The calling-number-avp command encapsulates the AVP22 attribute into an ICRQ message sent by an LAC in a new format. The new formats are described in Usage Guidelines.

The undo calling-number-avp command restores the default format for encapsulating the AVP22 attribute.

By default, the encapsulation format of the AVP22 attribute is as follows:

MAC address Interface type (eth|trunk) Slot number/Subcard number/Port number: Outer VLAN.Inner VLAN Option 82

For example: xxxx-xxxx-xxxx eth 0/1/1:10.20 huawei

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

When the device functions as an LAC and a non-Huawei device functions as an LNS, you need to encapsulate the AVP22 attribute in a new format to meet interconnection requirements.

If users access the network from an Eth-Trunk interface whose member interfaces are located on different boards, the calling-number-avp format version1 command must be configured to encapsulate AVP22 attribute in a new format because the slot IDs with which users get online may be changed.

After the radius-server calling-station-id include llid user-type { ppp | lns } * command is run in the RADIUS server group view, a user needs to send two authentication requests to the RADIUS server group. To enable an LAC to encapsulate LLID information into the AVP22 attribute in an ICRQ message to be sent to an LNS when the LAC receives the second authentication request from a user, run the calling-number-avp format llidcommand on the LAC. The LNS then encapsulates LLID information into the Calling-Station-Id attribute of a RADIUS packet to be sent to the RADIUS server.

To encapsulate the calling-station-id delivered by the RADIUS server on the LAC side into the AVP22 attribute, run the calling-number-avp format radius-force command. The configuration allows the calling-station-id to be sent to the LNS side through the AVP22 attribute.

If the trunk ID, VLAN ID, system name, and user MAC address need to be carried in the AVP22 attribute of the packets to be sent to the LNS, run the calling-number-avp?format?version3 command to specify the content to be encapsulated into the AVP22 attribute.

Prerequisites

The l2tp calling-number-avp enable command has been run to configure L2TP packets to carry the AVP22 attribute.

The radius-server calling-station-id include llid user-type { ppp | lns } * command has been run in the RADIUS server group view. If the radius-server calling-station-id include llid user-type { ppp | lns } * command has not been run in the RADIUS server group view, the AVP22 attribute is generated in the default format.

Configuration Impact

After this command is run, the AVP22 attribute is encapsulated in the following format into an ICRQ packet to be sent by the LAC:

Encapsulation format: System name#Slot/Subslot/Port#Pvlan:Cvlan

Pvlan is an outer VLAN and Cvlan is an inner VLAN.

If the length of the Calling-Number attribute received by the LNS exceeds 253 characters, the first 253 characters are used.

After the calling-number-avp format include command is run, the AVP22 attribute in ICRQ packets sent by the LAC will contain user-specified contents. If sysname is specified but the system name is longer than 30 characters, only the first 30 characters are included in the AVP22 attribute.If a user goes online with a single VLAN tag or a user goes online without a VLAN tag, if the encapsulation format is configured to include Pvlan or Cvlan, the VLAN carried in the ICRQ message is 0.

After you run the calling-number-avp format version1 include option82 command, the Option 82 information that begins with the number sign (#) is added to the end of the original encapsulation format. (The information carried in the Option 82 field is subject to the configuration of the option82-relay-mode include command.)

After the calling-number-avp format radius-force command is run, the LAC encapsulates the RADIUS-delivered Calling-Station-Id into the AVP22 attribute of an ICRQ message to be sent to the LNS.

After the calling-number-avp format version3 command is run, the information to be encapsulated into the AVP22 attribute of the ICRQ packet sent by the LAC is in the following format:

Encapsulation format:

In case of trunk: lag-Trunkid:Pvlan.Cvlan#SystemName###pppoe mac-address#

In case of not trunk: eth Slot/Subslot/Port:Pvlan.Cvlan#SystemName###pppoe mac-address#

Pvlan specifies the outer VLAN ID, and Cvlan specifies the inner VLAN ID. In case of a single-tagged VLAN, the value of Pvlan is vlanid and the value of Cvlan is 0. If no VLAN is specified, the values of Pvlan and Cvlan are both 0.

In LTS scenarios:

The slot information is from the tunnel board where the LTS user resides.
subslot and port are the information about the source tunnel interface bound to lns-group.
- If the source tunnel interface is a GE interface, the subslot and port values of the GE interface are used.
- If the source tunnel interface is a loopback interface, the subslot and port values are the invalid values 255 and 65535, respectively.
- If the source tunnel interface is a trunk interface, trunkid in lag-trunkid is the trunk ID of the trunk interface.
Both the inner and outer VLAN IDs are invalid values.
Sysname specifies the system name of the lts device.
mac specifies the virtual MAC address of the LNS user and consists of the tunnel-id and session-id of the LNS user. The first two bits of mac are both 0s, the middle two bits are tunneled, and the last two bits are sessionid.

By default, the AVP 22 attribute is encapsulated in the following formats:

In double-tagged VLAN scenarios: MAC address interface type (eth|trunk) slot ID/subcard ID/port number: outer VLAN. Inner VLAN option82

In single-tagged VLAN scenarios: MAC address interface (eth|trunk) slot ID/subcard ID/port number: 4096.single-tagged VLAN option82

In no VLAN scenarios: MAC address without a VLAN interface type (eth|trunk) slot ID/subcard ID/port number: 4096.4096 option82
