[Sysname-behavior-count] quit
[Sysname] qos policy count
[Sysname-qospolicy-count] classifier count behavior count
b. Apply the QoS policy to interfaces on devices along the forwarding path. In this example,
apply the QoS policy to the incoming traffic on GigabitEthernet 1/0/1 on Device B and
GigabitEthernet 2/0/1 on Device C.
The following shows the application on Device B:
[Sysname-qospolicy-count] quit
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] qos apply policy count inbound
3. After the time range, execute the display qos policy interface command to display traffic statistics
on the interfaces:
On GigabitEthernet 1/0/1 of Device B:
[Sysname-GigabitEthernet1/0/1] display qos policy interface gigabitethernet 1/0/1
Interface: GigabitEthernet1/0/1
Direction: Inbound
Direction: Inbound
Policy: count
Classifier: count
Operator: AND
Rule(s) : If-match ACL 3000
Behavior: count
Accounting Enable:
251 (Packets)
The output shows that a total of 251 packets match ACL 3000.
On GigabitEthernet 2/0/1 of Device C:
[Sysname-GigabitEthernet2/0/1] display qos policy interface gigabitethernet 2/0/1
Interface:GigabitEthernet2/0/1
Direction: Inbound
Direction: Inbound
Policy: count
Classifier: count
Operator: AND
Rule(s) : If-match ACL 3000
Behavior: count
Accounting Enable:
50 (Packets)
The output shows that a total of 50 packets match ACL 3000.
4. Compare the traffic statistics on the two interfaces. Packet loss or forwarding fault exists between
Device B and Device C.
