Configuring nesting
Nesting adds a VLAN tag to the matching packets to allow the VLAN-tagged packets to pass through
the corresponding VLAN. For example, you can add an outer VLAN tag to packets from a customer
network to a service provider network. This allows the packets to pass through the service provider
network by carrying a VLAN tag assigned by the service provider.
Configuration procedure
To configure nesting:
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
class exists.
3. Configure match criteria.
if-match
match-criteria
By default, no match
criterion is configured for
a traffic class.
For more information
about the match criteria,
see the
if-match
command in ACL and
QoS Command
Reference.
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
behavior exists.
6. Configure a VLAN tag
adding action.
nest top-most vlan
vlan-id
By default, no VLAN tag
adding action is
configured for a traffic
behavior.
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
policy exists.
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, no
class-behavior
association is configured
for a QoS policy.
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 a VLAN
• Applying the QoS policy globally
C
hoose one of the
application destinations
as needed.
By default, a QoS policy
is not applied.
