Network IP Interface Forwarding Class-Based Redirection
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 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 if an instance of the named policer queue-group exists on the ingress FP the PW packet
is received on. The user can apply a QoS filter matching the dot1.p 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 the PW is redirected does not exist, the redirection command
is failed. In this case, the packet classification is performed according to default classification rule
or the QoS filters defined in the ingress context of the network QoS policy applied to the network
IP interface the PW packet is received on.
