Example: Configuring CoS Queuing for GRE or IP-IP Tunnels
This example shows how to configure CoS queuing for GRE or IP-IP tunnels.
CoS queuing is not supported on GRE tunnels in chassis clusters.
Requirements
Before you begin:
Establish a main office and a branch office connected by a VPN using GRE or IP-IP tunneled interfaces.
Configure forwarding classes and schedulers. See Example: Assigning Forwarding Classes to Output Queues and Example: Configuring Class-of-Service Schedulers on a Security Device.
Configure a scheduler map and apply the scheduler map to the tunnel interface. See Example: Configuring and Applying Scheduler Maps.
Configure classifiers and apply them to the tunnel interface. See Example: Configuring Behavior Aggregate Classifiers.
Create rewrite rules and apply them to the tunnel interface. See Example: Configuring and Applying Rewrite Rules on a Security Device.
Overview
In this example, you enable tunnel queuing, define the GRE tunnel interface as gr-0/0/0, (Alternatively, you could define the IP-IP tunnel interface as ip-0/0/0.) and set the per unit scheduler. You then set the GRE tunnel’s line rate as 100 Mbps by using the shaper definition.
In Figure 1, Router A has
a GRE tunnel established with Router B through interface ge-1/0/0. Router A also has an IP-IP tunnel established with Router C through
interface ge-1/0/1. Router A is configured so that tunnel-queuing
is enabled. Router B and Router C do not have tunnel-queuing configured.

Configuration
Procedure
CLI Quick Configuration
To quickly configure this example, copy the
following commands, paste them into a text file, remove any line breaks,
change any details necessary to match your network configuration,
copy and paste the commands into the CLI at the [edit] hierarchy
level, and then enter commit from the configuration mode.
set chassis fpc 0 pic 0 tunnel-queuing set interfaces gr-0/0/0 unit 0 set interfaces gr-0/0/0 per-unit-scheduler set class-of-services interfaces gr-0/0/0 unit 0 shaping-rate 100m
Step-by-Step Procedure
To configure CoS queuing for GRE tunnels:
Enable tunnel queuing on the device.
[edit] user@host# set chassis fpc 0 pic 0 tunnel-queuing
Define the GRE tunnel interface.
[edit] user@host# set interfaces gr-0/0/0 unit 0
Define the per-unit scheduler for the GRE tunnel interface.
[edit] user@host# set interfaces gr-0/0/0 per-unit-scheduler
Define the GRE tunnel’s line rate by using the shaper definition.
[edit] user@host# set class-of-services interfaces gr-0/0/0 unit 0 shaping-rate 100m
Results
From configuration mode, confirm your configuration
by entering the show class-of-service interfaces gr-0/0/0, show interfaces gr-0/0/0 , and show chassis commands. If the output does not display the intended configuration,
repeat the configuration instructions in this example to correct it.
[edit]
user@host# show class-of-service interfaces gr-0/0/0
unit 0 {
shaping-rate 100m;
}
[edit]
user@host# show interfaces gr-0/0/0
per-unit-scheduler;
unit 0;
[edit]
user@host# show chassis
fpc 0 {
pic 0 {
tunnel-queuing;
}
}
If you are done configuring the device, enter commit from configuration mode.
Verification
Confirm that the configuration is working properly.

Purpose
Verify that the device is configured properly for tunnel configuration.
Action
From configuration mode, enter the show interfaces
queue gr-0/0/0.0 command.
If you enter gr-0/0/0.0 only, queue information
for all tunnels is displayed. If you enter gr-0/0/0.0,
queue information for the specific tunnel is displayed.

Verifying a CoS Queuing for IP-IP Tunnel Configuration
Purpose
Verify that the device is configured properly for tunnel configuration.
Action
From configuration mode, enter the show interfaces
queue ip-0/0/0.0 command.
If you enter ip-0/0/0.0 only, queue information
for all tunnels is displayed. If you enter ip-0/0/0.0,
queue information for the specific tunnel is displayed.
