Pwhe Without Qos Policy - Cisco ASR 9000 Series Configuration Manual

Configuring Modular QoS Service Packet Classification
Note
• The supported policy combinations on PWHE main and subinterfaces for LC in the co-existence queuing
mode are:
Note
• The supported policy combination on PWHE main and subinterfaces for LC in the co-existence
non-queuing mode is:
Note
When PWHE interface is created, and no PWHE QoS policy is applied on it, PWHE traffic will pass

through the member interface default queues.

PWHE without QoS policy

The following two cases represent the default behavior of the PWHE interfaces:
• PWHE ingress to core facing egress (access to core) - DSCP/ precedence value from customer IP packet
is copied to EXP of all imposed labels (VPN and transport)in the core-facing direction.
• PWHE egress (core to access) - DSCP/precedence value from customer IP packet is copied to EXP of
all imposed labels (VC and transport) in the access-facing direction.
In ingress direction, policies with priority but no queuing actions in the policy-map will
use the member port default queues. In egress direction, priority is treated as queuing
action so dedicated queue is created for it.
• PWHE aggregate shaper policy on the PWHE main interface. Non-queuing policies on subinterfaces
with or without SPI.
• PWHE aggregate shaper policy on the PWHE main interface. Up to 2 level queuing policies on
subinterfaces with or without SPI.
In the ingress direction, the PWHE subinterface polices with priority but no queuing
action in the policy-map will use the queues created for the PWHE main interface. In
the egress direction, priority is treated as queuing action so dedicated queues will be
created for the subinterface. If the PWHE main interface does not have queuing policy,
its subinterface with non-queuing policies will use the pindown interface default queues.
• PWHE aggregate shaper on the PWHE main interface. Non-queuing policies on subinterfaces.
In ingress and egress direction, the PWHE subinterface policies with priority but no
queuing action in the policy-map will use the queues created for the PWHE main
interface. If the PWHE main interface does not have queuing policy, its subinterface
policies with priority but no queuing action will use the pin-down interface default
queues.
