Outgoing Traffic

Outgoing traffic is queued according to traffic class/color combinations. The applied combination can be the same as was set on the ingress line module, or it can be reset on the egress line module by egress IP policy.

Figure 62 illustrates how the initial value of the EXP bits is set for the first label pushed. Figure 63 illustrates how the EXP bits can be changed for all labels, including the first label, by attached policies or per-VR EXP rules. The following section describes in detail how the EXP bits value is set for outgoing traffic.
