This is an example of a 3-level output policy. You can attach this policy only to physical ports and not
to EFP service instances.

This is an example of a 2-level output policy. You can attach this policy to physical ports or to EFP
service instances.

Default MPLS and EoMPLS QoS Configuration
QoS is disabled. Packets are not modified, and the CoS, DSCP, and IP precedence values in the packet
are not changed. Traffic is switched in pass-through mode (packets are switched without any rewrites
and classified as best effort without any policing).
The default behavior for VLAN and port-based EoMPLS packets is to use a value of 0 in the EXP bits
of the virtual-connection and tunnel labels. The default behavior for L3VPN MPLS packets is to relay
the IP Precedence bits into the EXP bits of the virtual-connection and tunnel labels. You can change the
default behavior for VLAN- or port-based EoMPLS by applying a hierarchical QoS policy.
