This command specifies which Dot1Q tag position Dot1P bits in a QinQ encapsulated packet should

be used to evaluate Dot1P QoS classification.

The match-qinq-dot1p command allows the top or bottom PBits to be used when evaluating the

applied sap-ingress QoS policy's Dot1P entries. The top and bottom keywords specify which

position should be evaluated for QinQ encapsulated packets.

The mandatory de keyword is added to the above command line to specify on a per SAP basis the

source for the DE bit. The de keyword is effective if there is an explicit command in the sap ingress

policy that specifies the use of DE bit for QoS Classification – for example, de-1-out-profile.

Otherwise the rules for the matching of dot1p bits will apply the same way for the DE bit whenever

the usage is activated explicitly. The text will be updated to include also the DE bit in the header of

the tables next to the dot1p bits.

The no form of this command reverts the dot1p and de bits matching to the default tag

By default, the bottom most service delineating Dot1Q tags Dot1P bits are used. The following

defines the default behavior for Dot1P evaluation when the match-qinq-dot1p command is not

no match-qinq-dot1p (no filtering based on p-bits)

top or bottom must be specified to override the default QinQ dot1p behavior
