Configuring QoS for Tunnel-Server Ports for L2TP LNS Sessions

You can configure QoS for a tunnel-service port that can be used as a dynamic interface associated with an L2TP LNS session.

Before you configure QoS for a tunnel-server port:

• Configure the dedicated or shared tunnel-server port.

  See JunosE Physical Layer Configuration Guide.

  Note: Dedicated and shared tunnel-server ports on the ES2 10G ADV LM do not support QoS profiles on server-port interfaces and IP floating interfaces (IP interfaces that stack over MPLS stacked tunnels). However, you can configure QoS profiles for dedicated and shared tunnel-server ports on ES2 10G ADV LMs on interfaces other than server-port interfaces (such as ATM or Ethernet). On ES2 10G ADV LMs, you can also configure QoS profiles for dedicated and shared tunnel-server ports for L2TP LNS sessions only on interface types other than the server-port interface.

• Configure the traffic classes.

  See Configuring Traffic Classes That Define Service Levels.

• Configure the queuing hierarchy.

  See Configuring Queue Profiles to Manage Buffers and Thresholds.

• Configure the scheduler hierarchy and shaping with scheduler profiles.

  See Configuring a Scheduler Hierarchy.

To configure QoS for the tunnel-server port:

1. Create the QoS profile.
   host1(config)#qos-profile lns-tsport
2. Configure group nodes for the tunnel-server ports.
   host1(config-qos-profile)#ip queue traffic-class best-effort scheduler-profile business-data queue-profile data host1(config-qos-profile)#ip queue traffic-class video scheduler-profile video queue-profile video host1(config-qos-profile)#ip queue traffic-class voice scheduler-profile voice queue-profile voice host1(config-qos-profile)#server-port group video host1(config-qos-profile)#server-port group data host1(config-qos-profile)#server-port group voice scheduler-profile strict-priority
3. Create and attach the QoS port-type profile for server ports.
   host1(config)#qos-port-type-profile server-port qos-profile lns-tsport
