Table 76: Default Forwarding Classes - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

NOTE: On IQ2 and IQ2-E interfaces and MX Series interfaces, when a VLAN tag is
pushed, the inner VLAN IEEE 802.1p bits are copied to the IEEE bits of the VLAN or
VLANs being pushed. If the original packet is untagged, the IEEE bits of the VLAN or
VLANs being pushed are set to 0.
Specifying an Output Priority Map
An output priority map identifies egress traffic with specified queue classification
and packet loss priority (PLP), and classifies that traffic as premium.
If you include a premium-priority policer, you can specify an output priority map by
including the
ethernet-policer-profile output-priority-map]
You can define a forwarding class, or you can use a predefined forwarding class.
Table 76 on page 789 shows the predefined forwarding classes and their associated
queue assignments.

Table 76: Default Forwarding Classes

For more information about CoS forwarding classes, see the JUNOS Class of Service
Configuration Guide. For a configuration example, see "Example: Configuring Gigabit
Ethernet Policers" on page 792.
Applying a Policer
On all MX Series Router interfaces, Gigabit Ethernet IQ, IQ2, and IQ2-E PICs, and
Gigabit Ethernet PICs with SFPs (except the 10-port Gigabit Ethernet PIC and the
built-in Gigabit Ethernet port on the M7i router), you can apply input and output
policers that define rate limits for premium and aggregate traffic received on the
