Configuration procedure 
Before you make the configuration, make sure the devices can reach each other.

address.

NQA collaboration configuration example 
Network requirements 
As shown in  Figure 51, configure a static route to Device C on Device A, with Device B as the next hop. 
Associate the static route, track entr y, and NQA test group to verify whether static route is active in real 
time.

Configuration procedure 
1. Assign each interface an IP  address. (Details not shown.) 
2. On Device A, configure a unicast static route an d associate the static route with a track...

Verifying the configuration 
# On Device A, display information about all the track entries.

The output shows that the next hop 10.2.1.1 of the  static route is not reachable, and the status of 
the track entry is negative. Th e static route does not work.

sFlow operation 
sFlow operates in the following ways: 
1. Before enabling the sFlow function, configure the sFlow agent and sFlow collector on the device.  
2. With flow sampling enabled on an Ethernet  interface, the sFlow agent samples packets and 
encapsulates them into sFlow packe ts. For the configuration, see Configuring flow sampling. 
3. With counter sampling enabled on an Ethernet inte rface, the sFlow agent periodically collects the 
statistics of the interface and encapsulates the...

sFlow configuration example 
Network requirements 
As shown in Figure 53, Ho st A is connected with the server through the device (sFlow agent). 
Enable sFlow (including flow sampling and counter sampling) on GigabitEthernet 1/0/1 to monitor 
traffic on the port. The device sends sFlow packets through GigabitEthernet 1/0/3 to the sFlow collector, 
which analyzes the sFlow packets and displays results.
