Overview of Configuring ANCP for QoS Adaptive Mode

QoS adaptive mode enables the system to shape VLAN and ATM VC downstream rates received from ANCP by dynamically creating QoS parameter instances associated with the ANCP (L2C) downstream application. The system can QoS adjust VLAN and ATM VC downstream rates received from ANCP when you enable QoS adaptive mode.

When QoS adaptive mode is enabled, ANCP dynamically creates QoS parameter instances associated with the QoS downstream rate application. ANCP also determines the value the system uses when recalculating the QoS shaping rate. The values of the parameter instances track the bandwidth of the local loop that is communicated by ANCP.

All QoS parameter instances associated with the neighbor can be removed from the topology discovery table. After clearing ANCP entries or neighbor sessions, the system recreates the QoS parameter instances when QoS adaptive mode is enabled and ANCP learns the rates again.

For more information about the QoS downstream rate application and QoS parameters, see QoS Downstream Rate Application Overview in JunosE Quality of Service Configuration Guide.
