Service Ingress QoS Policy Forwarding Class Commands
VPRN). When the policy is applied to a Layer 2 SAP (i.e., Epipe or VPLS), the remarking definitions are
silently ignored.
In the case where the policy is applied to a Layer 3 SAP, the in-profile remarking definition will be applied
to packets that have been classified to the forwarding class or sub-class. It is possible for a packet to match a
classification command that maps the packet to a particular forwarding class or sub-class only to have a
more explicit (higher priority match) override the association. Only the highest priority match forwarding
class or sub-class association will drive the in-profile marking.
The in-remark command is only applicable to ingress IP routed packets that are considered in-profile. The
profile of a SAP ingress packet is affected by either the explicit in-profile/out-of-profile definitions or the
ingress policing function applied to the packet. The following table shows the effect of the in-remark
command on received SAP ingress packets. Within the in-profile IP packet's ToS field, either the six DSCP
bits or the three precedence bits are remarked.
Non-Routed, Policed In-Profile
Non-Routed, Policed Out-of-Profile
Non-Routed, Explicit In-Profile
Non-Routed, Explicit Out-of-Profile
IP Routed, Policed In-Profile
IP Routed, Policed Out-of-Profile
IP Routed, Explicit In-Profile
IP Routed, Explicit Out-of-Profile
The no form of the command disables ingress remarking of in-profile packets classified to the forwarding
class or sub-class.
Parameters dscp dscp-name — This parameter is one of two mutually exclusive settings that are applicable to the in-
remark command. The in-remark command can be configured to either remark the DiffServ Code Point
(DSCP) six bit value or the three Precedence bits. The dscp parameter specifies that the matching
packets DSCP bits should be overridden with the value represented by dscp-name.
32 characters, maximum,
represented by dscp-name. It must be one of the predefined DSCP names defined on the system.
