Example: Configuring Virtual LAN Queuing and Shaping in PTX Series Packet Transport Routers
You can enable virtual LAN (VLAN) queuing on 100-Gigabit Ethernet interfaces on PTX Series Packet Transport Routers and specify a traffic-shaping rate for each VLAN.
Requirements
This example uses the following hardware and software components:
Junos OS Release 13.2 or later.
One PTX5000 router.
Overview
This example shows how to configure 10 VLANs, enable class-of-service (CoS) queuing, and specify a traffic-shaping rate for each VLAN. The total traffic-shaping rate for all VLANs cannot exceed 100 Gbps.
Configuration
CLI Quick Configuration
To configure VLAN queuing and traffic shaping on the PTX5000 router, copy the following commands and paste them into the terminal window of the router:
[edit] set interfaces et-5/0/0 vlan-tagging set interfaces et-5/0/0 per-unit-scheduler set interfaces et-5/0/0 unit 0 vlan-id 0 set interfaces et-5/0/0 unit 1 vlan-id 1 set interfaces et-5/0/0 unit 2 vlan-id 2 set interfaces et-5/0/0 unit 3 vlan-id 3 set interfaces et-5/0/0 unit 4 vlan-id 4 set interfaces et-5/0/0 unit 5 vlan-id 5 set interfaces et-5/0/0 unit 6 vlan-id 6 set interfaces et-5/0/0 unit 7 vlan-id 7 set interfaces et–5/0/0 unit 8 vlan-id 8 set interfaces et-5/0/0 unit 9 vlan-id 9 set class-of-service interfaces et-5/0/0 unit 0 shaping-rate 5g set class-of-service interfaces et-5/0/0 unit 1 shaping-rate 10g set class-of-service interfaces et-5/0/0 unit 2 shaping-rate 20g set class-of-service interfaces et-5/0/0 unit 3 shaping-rate 5g set class-of-service interfaces et-5/0/0 unit 4 shaping-rate 10g set class-of-service interfaces et-5/0/0 unit 5 shaping-rate 10g set class-of-service interfaces et-5/0/0 unit 6 shaping-rate 5g set class-of-service interfaces et-5/0/0 unit 7 shaping-rate 5g set class-of-service interfaces et-5/0/0 unit 8 shaping-rate 10g set class-of-service interfaces et-5/0/0 unit 9 shaping-rate 20g
Procedure
Step-by-Step Procedure
To configure the PTX5000 router:
Enable the reception and transmission of 8021.q VLAN-tagged frames on the interface:
[edit interfaces] user@host# set et-5/0/0 vlan-tagging
Specify a VLAN identifier for each logical interface:
[edit interfaces] user@host# set et-5/0/0 unit 0 vlan-id 0 user@host# set et-5/0/0 unit 1 vlan-id 1 user@host# set et-5/0/0 unit 2 vlan-id 2 user@host# set et-5/0/0 unit 3 vlan-id 3 user@host# set et-5/0/0 unit 4 vlan-id 4 user@host# set et–5/0/0 unit 5 vlan-id 5 user@host# set et-5/0/0 unit 6 vlan-id 6 user@host# set et-5/0/0 unit 7 vlan-id 7 user@host# set et-5/0/0 unit 8 vlan-id 8 user@host# set et-5/0/0 unit 9 vlan-id 9
Configure per-VLAN traffic shaping by specifying the amount of bandwidth to be allocated to each logical interface:
[edit class-of-service interfaces] user@host# set et-5/0/0 unit 0 shaping-rate 5g user@host# set et-5/0/0 unit 1 shaping-rate 10g user@host# set et-5/0/0 unit 2 shaping-rate 20g user@host# set et-5/0/0 unit 3 shaping-rate 5g user@host# set et-5/0/0 unit 4 shaping-rate 10g user@host# set et-5/0/0 unit 5 shaping-rate 10g user@host# set et-5/0/0 unit 6 shaping-rate 5 g user@host# set et-5/0/0 unit 7 shaping-rate 5g user@host# set et-5/0/0 unit 8 shaping-rate 10g user@host# set et-5/0/0 unit 0 shaping-rate 20g

Confirm your results by entering the show interfaces and show class-of-service commands:
user@host# show interfaces
