de-mark-outer
Syntax [no] de-mark-outer [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 outer or single VLAN tag on a
qinq or dot1q SAP, respectively, 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 outer or single tags of
packets of this forwarding class regardless of their in/out of profile status.
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 DE bit for both the BVID and ITAG.
This command takes precedence over the de-mark command if both are specified in the same policy and
over the default action.
If no de-mark commands are used, the DE bit is preserved if an ingress outer or single tag exists, or set to
zero otherwise.
This command is supported on FP2 and higher based hardware, and is otherwise ignored.
Values
dot1p-inner
Syntax [no] dot1p-inner {dot1p-value | in-profile dot1p-value out-profile dot1p-value}
Context config>qos>sap-egress>fc
Description This command explicitly defines the egress inner VLAN tag IEEE 802.1P (dot1p) bits marking for fc-name.
When the marking is set, all packets of fc-name that have either an inner IEEE 802.1Q or IEEE 802.1P
encapsulation on a qinq SAP will use the explicitly defined dot1p-value. If the egress packets for fc-name
are not IEEE 802.1Q or IEEE 802.1P qinq encapsulated, this command has no effect.
The optional in-profile | dot1p-value out-profile dot1p-value parameters on the dot1p-inner command
adds the capability to mark the in and out of profile status on an egress qinq SAP. The command with the
additional parameters may be used on the SAP when the internal in and out of profile status needs to be
communicated to an access network/customer device that does not support the DE bit. Once the in-profile
keyword is added, then the rest of the structure must be specified.
When these commands are used, the DE Bit or the equivalent field is left unchanged by the egress
processing if an inner tag exists. If a new inner tag is added, the related DE bit is set to 0. The in or out
profile status may be indicated via the setting of the DE bit setting if the de-mark(-inner) command is used.
The two versions of the command (with and without parameters) are mutually exclusive.
This command takes precedence over the dot1p command if both are specified in the same policy and over
the default action where the marking is taken from packet received at ingress.
The configuration of qinq-mark-top-only under the SAP egress takes precedence over the use of the
