Ingress Criteria Classification Directly to Policer
It is possible to classify traffic directly to a policer, independent of the policer/queue assigned to
the traffic's forwarding class. This is supported at SAP ingress when using one of the following
statements: ip-criteria, ipv6-critera or mac-criteria.
The standard mechanisms are still used to assign a forwarding class to the related traffic, and this
forwarding class continues to be used for QOS processing at egress.
This is supported on all FP2 and higher based line cards. The use of explicitly configured
broadcast, unknown, or multicast policers is not supported. QPPB processing takes precedence
over this feature.
This could be used, for example, when it is required that ingress OAM traffic is not subject to the
same QOS control as other customer traffic on a given SAP. The OAM traffic could be classified
based on its source MAC address (for example, with an OUI of 00-xx-yy as configured below) and
directed to policer 1 while the remainder of the customer's traffic is processed using ingress queue
1. This is shown in
The configuration would be as follows:
