Configuring traffic filtering
You can filter in or filter out traffic of a class by associating the class with a traffic filtering action. For
example, you can filter packets sourced from an IP address according to network status.
Configuration procedure
To configure traffic filtering:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create a traffic class and
enter traffic class view.
traffic classifier
classifier-name
[
operator
{
and
|
or
} ]
By default, no traffic classes
exist.
3.
Configure a match
criterion.
if-match match-criteria
By default, no match criterion
is configured.
4.
Return to system view.
quit
N/A
5.
Create a traffic behavior
and enter traffic behavior
view.
traffic behavior behavior-name
By default, no traffic behaviors
exist.
6.
Configure the traffic
filtering action.
filter
{
deny
|
permit
}
By default, no traffic filtering
action is configured.
7.
Return to system view.
quit
N/A
8.
Create a QoS policy and
enter QoS policy view.
qos policy
policy-name
By default, no QoS policies
exist.
9.
Associate the traffic class
with the traffic behavior in
the QoS policy.
classifier
classifier-name
behavior
behavior-name
[
insert-before
before-classifier-name
]
By default, a traffic class is not
associated with a traffic
behavior.
10.
Return to system view.
quit
N/A
11.
Apply the QoS policy.
•
Applying the QoS policy to an
interface
•
Applying the QoS policy to VLANs
•
Applying the QoS policy globally
•
Applying the QoS policy to a control
plane
•
Applying the QoS policy to a user
profile
Choose one of the application
destinations as needed.
By default, no QoS policy is
applied.
12.
(Optional.) Display the
traffic filtering
configuration.
display traffic behavior user-defined
[
behavior-name
]
Available in any view.
Configuration example
Network requirements
As shown in
, configure traffic filtering on Ten-GigabitEthernet 1/0/1 to deny the incoming
packets with a source port number other than 21.
