Apply a QoS policy globally 
You can apply a QoS policy globally to mirror the traffic in a specified direction on all ports.  
To apply a QoS policy globally: 
 
Step Command 
1.   Enter system view. 
system-view 
2.  Apply a QoS policy globally.  qos apply policy
 policy-name  global { inbound  | 
outbound  } 
 
For more information about the  qos apply policy command, see ACL and QoS Command Reference .

erent departments of a company use IP addresses on different subnets. The marketing and 
technology departments use the IP addresses on subnets 192.168.1.0/24 and 192.168.2.0/24 
respectively. The working hour of the company is from 8:00 to 18:00 on weekdays.

Configuring NQA 
Overview 
Network Quality Analyzer (NQA) can perform various types of tests and collect network performance 
and service quality parameters such as delay jitter,  time for establishing a TCP connection, time for 
establishing an FTP connecti on, and file transfer rate. 
With the NQA test results, you can diagnose an d locate network faults, be aware of network 
performance in time and take proper actions to correct any problems.

•  The application module takes actions when the tracked object changes its state. 
The following describes how a static ro ute is monitored through collaboration. 
1. NQA monitors the reachability to 192.168.0.88. 
2. When 192.168.0.88 becomes unreachable, NQA notifies the track module of the change. 
3. The track module notifies the state change to the static routing module  
4. The static routing module sets the static route as invalid. 
For more information about collaboration and the track...

The counting for the average or accumulate thresh old type is performed per test, but the counting 
for the consecutive type is perfor med after the test group starts. 
•   Triggered actions 
The following actions may be triggered: 
{  none —NQA only records events for terminal display; it does not send trap information to the 
network management server. NQA DNS tests do not support the action of sending trap 
messages. The action to be triggered in DNS tests can only be the default one,  none.

NQA client and server 
A device with NQA test groups configured is an NQA client, and the NQA client initiates NQA tests. An 
NQA server makes responses to probe packets destined to the specified destination address and port 
number.  
Figure 39  Relationship between the NQA client and NQA server 
 
 
Not all test types require the NQA server. Only the TCP, UDP echo, UDP jitter, or voice test requires both 
the NQA client and server, as shown in  Figure 39.
