Service Egress QoS Policy Forwarding Class Commands
Independently the in or out profile status may be indicated via the setting of the DE bit setting if the de-mark
command is used.
In the PBB case, for a Backbone SAP (B-SAP) and for packets originated from a local I-VPLS/PBB-Epipe,
the command dictates the marking of the dot1p bits for both the BVID and ITAG.
The commands dot1p-inner and dot1p-outer take precedence over the dot1p command if both are
specified in the same policy.
The no form of the command sets the IEEE 802.1P or IEEE 802.1Q priority bits to 0.
Default 0
in-profile dot1p-value — Specifies the 802.1p value to set for in-profile frames in this forwarding class.
Values
out-profile dot1p-value — specifies the 802.1p value to set for out-profile frames in this forwarding class.
Values
de-mark-inner
Syntax [no] de-mark-inner [force de-value]
Context config>qos>sap-egress>fc
Description This command is used to explicitly define the marking of the DE bit in the inner VLAN tag for fc fc-name
on a qinq SAP according to the in and out of profile status of the packet.
If no de-value is present, the default values are used for the marking of the DE bit: for example, 0 for in-
profile packets, 1 for out-of-profile ones– see IEEE 802.1ad-2005 standard.
If the de-value is included in the command line then this value is used for all the inner tags of packets of this
forwarding class regardless of their in/out of profile status.
This command takes precedence over the de-mark command if both are specified in the same policy and
over the default action.
The configuration of qinq-mark-top-only under the SAP egress takes precedence over the use of the de-
mark-inner in the policy, i.e. the inner VLAN tag is not remarked when qinq-mark-top-only is configured
(the marking used for the inner VLAN tag is based on the current default which is governed by the marking
of the packet received at the ingress to the system).
If no de-mark commands are used, the DE bit is preserved if an ingress inner tag exists, or set to zero
otherwise.
This command is only supported on FP2 and higher based hardware, and is otherwise ignored.
