.SH NAME
dlcosmk \- Data Layer Class of Service Marker
.SH DESCRIPTION
.sp
.LP
The \fBdlcosmk\fR marker is an action module that is executed as a result of
classifying or metering packets. It marks the packet with a user priority
defined by the\fI IEEE 801.D\fR standard. This feature is only possible on a
\fBVLAN\fR device.
.sp
.LP
The 3-bit user priority is part of the \fI802.1Q\fR \fBVLAN\fR header tag that
is part of the ethernet header (carrying the IP packet).
