dlcosmk

- Data Layer Class of Service Marker

Description

The dlcosmk 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 IEEE 801.D standard. This feature is only possible on a VLAN device.

The 3-bit user priority is part of the 802.1Q VLAN header tag that is part of the ethernet header (carrying the IP packet).

Statistics

The dlcosmk module exports the following statistics through kstat:
