Ingress packet classification

When a PW is redirected to use a policer queue-group, the classification of the packet for the purpose of FC and profile determination is performed according to the default classification rule or the QoS filters defined in the ingress context of the network QoS policy applied to the PW. This is true regardless of whether an instance of the named policer queue-group exists on the ingress FP that the PW packet is received on. The user can apply a QoS filter matching the dot1p in the VLAN tag corresponding to the Ethernet port encapsulation, the EXP in the outer label when the tunnel is an LSP, the DSCP in the IP header if the tunnel encapsulation is GRE, and the DSCP in the payload’s IP header if the user enabled the ler-use-dscp option and the PW terminates in IES or VPRN service (spoke-interface).

When the policer queue-group name to which PW is redirected does not exist, the redirection command fails. In this case, the packet classification is performed according to the default classification rule or the QoS filters defined in the ingress context of the network QoS policy applied to the network IP interface that the PW packet is received on.
