ANCP commands
This feature is available only when the system operates in standard mode. For more information about the system operating modes, see device management in Fundamentals Configuration Guide.
aging-time
Use aging-time to configure the aging time for DSL entries.
Use undo aging-time to restore the default.
Syntax
aging-time value
undo aging-time
Default
The aging time for DSL entries is 150 seconds.
Views
ANCP neighbor view
Predefined user roles
network-admin
Parameters
value: Configures the aging time, in the range of 0 to 65535 seconds. If you set the value to 0, the system deletes a DSL entry once the DSL goes down.
Usage guidelines
|
|
IMPORTANT: If an ANCP neighbor needs to reboot the DSL after receiving a service profile, the DSL entry aging time configured for the neighbor must be long enough for the neighbor to complete the reboot. |
The ANCP server records DSL information in DSL entries. If a user on a DSL goes offline, the server will remove the corresponding DSL entry when its aging timer expires.
Examples
# Configure the DSL entry aging time as 100 seconds for ANCP neighbor test1.
<Sysname> system-view
[sysname] ancp neighbor test1
[sysname-ancp-neighbor-test1] aging-time 100
ancp access-loop-configure
Use ancp access-loop-configure to assign a service profile to a DSL from the ANCP server.
Syntax
ancp access-loop-configure circuit-id circuit-id service-profile profile-name [ timeout time-value ]
Views
System view
Predefined user roles
network-admin
Parameters
circuit-id circuit-id: Specifies a DSL ID, a case-sensitive string of 1 to 63 characters. You can use display ancp access-loop to view the ID of a DSL.
service-profile profile-name: Specifies a service profile by its name, a case-sensitive string of 1 to 64 characters.
timeout time-value: Configures the timeout timer for the client to respond, in the range of 0 to 60 seconds. The default timeout timer is 5 seconds. If you set the timer to 0, the server does not wait for the client to respond.
Usage guidelines
This command assigns a service profile to a DSL from the server. The service profile must already exist on the client.
Examples
# Assign service profile text-profile to DSL Dslam1/1:100 and set the timeout timer to 0.
<Sysname> system-view
[Sysname] ancp access-loop-configure circuit-id Dslam1/1:100 service-profile text-profile timeout 0
# Assign service profile text-profile to DSL Dslam1/1:100 and use the default timeout timer. (The DSL does not exist.)

ancp session interval
Use ancp session interval to configure the adjacency timer for sending SYN packets.
Use undo ancp session interval to restore the default.
Syntax
ancp session interval interval
undo ancp session interval
Default
The adjacency timer is 25 seconds.
Views
System view
Predefined user roles
network-admin
Parameters
interval: Configures the adjacency timer, in the range of 1 to 25 seconds.
Usage guidelines
The ANCP server and the ANCP client exchange SYN packets to negotiate adjacency timers. The two ends use the longer adjacency timer to send SYNACK and ACK packets.
If you modify the adjacency timer after an ANCP adjacency is established, the change does not take effect immediately. The change takes effect after the ANCP adjacency is disconnected and adjacency timers are negotiated again.
Examples
# Configure the adjacency timer as 15 seconds.
<Sysname> system-view
[sysname] ancp session interval 15
ancp session retransmit
Use ancp session retransmit to configure the maximum number of retransmission attempts for SYN and SYNACK packets.
Use undo ancp session retransmit to restore the default.
Syntax
ancp session retransmit retransmit-value
undo ancp session retransmit
Default
The maximum number of retransmission attempts for SYN and SYNACK packets is 10.
Views
System view
Predefined user roles
network-admin
Parameters
retransmit-value: Configures the maximum number of retransmission attempts, in the range of 3 to 255.
Usage guidelines
The ANCP server retransmits a SYN or SYNACK message if it does not receive the message from the client before the adjacency timer expires. If the client does not respond after the retransmission attempts reach the maximum, the server closes the TCP connection.
Examples
# Configure a maximum of 100 retransmission attempts.
<Sysname> system-view
[sysname] ancp session retransmit 100
ancp source-interface
Use ancp source-interface to configure a global source interface.
Use undo ancp source-interface to restore the default.
Syntax
ancp source-interface loopback interface-number
undo ancp source-interface
Default
No global source interface is configured.
Views
System view
Predefined user roles
network-admin
Parameters
loopback interface-number: Specifies a loopback interface as the global source interface.
Usage guidelines
You must configure one global source interface for all adjacencies or one neighbor-specific source interface for each adjacency. The global source interface applies to all adjacencies. The ANCP server prefers the neighbor-specific source interface over the global source interface when it communicates with the specified neighbor.
The ANCP server uses one of the following addresses as the source IP address for TCP packets sent to an ANCP neighbor:
· The primary IPv4 address of the source interface.
· The first IPv6 global unicast address of the source interface.
If you delete the global source interface, the device closes the TCP port 6068 for neighbors without a neighbor-specific source interface. If you change the global source interface, the device uses the IP address of the new source interface. The delete or change operation does not affect existing ANCP adjacencies.
Examples
# Configure loopback 100 as the global source interface.
<Sysname> system-view
[sysname] ancp source-interface loopback 100

Parameters
peer-id: Specifies an ANCP neighbor ID, in the format of H-H-H. The ID is the MAC address of a client.
Usage guidelines
The ANCP server uses ANCP neighbor IDs to identify ANCP clients. If the MAC address of a client does not match any ANCP neighbor ID, the server closes the TCP connection to the client.
A neighbor ID uniquely identifies an ANCP neighbor. If you remove a neighbor ID, the server closes the TCP connection to the corresponding neighbor.
Examples
