Disable remarking the CLP bit of ATM
packets.
This behavior applies only in the outbound direction of interfaces and ATM PVCs.
XVIII. Configuring/disabling policy embedding
After defining a class using the traffic classifier command, you can have it perform the
associated behavior defined in its policy and in addition, use a child policy to further
classify the class, having it perform the behavior defined in the child policy. You can
thus implement policy embedding. To understand how policy embedding works, refer to
the section 3.8.5 "Integrated QoS Policy Embedding and LR Configuration Example".
Perform the following configuration in traffic behavior view.
Table 3-51 Configure/disable policy embedding
Associate a child policy to the behavior
Disable policy embedding
When embedding a child policy in a policy, note that:
Policy embedding is two-tier only.
If both of them are configured with the remark behavior, only the remark setting in
the child policy is executed. If both of them are configured with CAR or GTS, the
two CAR or GTS settings are executed, but the one in the child policy is executed
first. If both of them are configured with queuing (LR is mandatory for the policy in
this case), the packets that conform to the LR setting are enqueued according to
the policy and the nonconforming packets are enqueued according to the child
policy.
Make sure that LR is applied to the class associated with the parent policy before
embedding a child policy configured with the queue ef, queue af, or queue wfq
behavior.
Policy embedding can be applied to physical interfaces, subinterfaces, FR PVCs,
and ATM PVCs.
Policy embedding can be applied in both inbound and outbound directions of an
interface or PVC. However, you cannot configure the child policy with LR, CBQ,
GTS, FR DE remark, or CLP remark in the inbound direction, or configure FR DE
remark or ATM CLP remark in the outbound direction. In addition, for the child
policy, 802.1p remark is valid only on Ethernet interfaces (excluding virtual
Ethernet interfaces) and CBQ is valid on the interfaces except for ATM physical
