or in the Tunnel/VC label column differentiates the behavior when qos exp encode policy is ON
(default) or OFF.

or in the Outgoing packet Outer VLAN column differentiates the behavior when qos pcp encode
policy is ON (default) or OFF.

Example 1: CoS behavior for dual-tagged to dual-tagged VLL endpoints

Table

84

shows a detailed example of the CoS behavior in a dual-tagged to dual-tagged VLL

endpoint configuration. The table shows the difference in behavior for VLL tagged mode (described
in

Table

82

) versus VLL raw mode (described in

Table

83

).
