FC mapping based on EXP bits

Use the lsp-exp command to set the sap-ingress qos policy on Ethernet L2 SAPs to perform FC mapping based on EXP bits.

The lsp-exp option causes the forwarding class and drop priority of incoming traffic to be determined by the mapping result of the EXP bits in the top label.

The following example displays FC mapping based on EXP bits:

*A:Dut-T>config>qos>sap-ingress# info

            queue 1 create
            exit
            queue 2 create
            exit
            queue 3 create
            exit
            queue 11 multipoint create
            exit
            fc "af" create
                queue 2
            exit
            fc "be" create
                queue 1
            exit
            fc "ef" create
                queue 3
            exit
            lsp-exp 0 fc "be" priority low
            lsp-exp 1 fc "af" priority high
