de-mark
Syntax [no] de-mark [force de-value]
Context config>qos>sap-egress>fc
Description
This command is used to explicitly define the marking of the DE bit for fc fc-name according to the in and
out of profile status of the packet (fc-name may be used to identify the dot1p-value).
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.
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.
If this command is not used, the DE bit should be preserved if an ingress TAG exist or set to zero otherwise.
If the de-value is specifically mentioned in the command line it means this value is to be used for all the
packets of this forwarding class regardless of their in/out of profile status.
The commands de-mark-inner and de-mark-outer take precedence over the de-mark command if both
are specified in the same policy.
Values
dot1p
Syntax [no] dot1p {dot1p-value | in-profile dot1p-value out-profile dot1p-value}
Context config>qos>sap-egress>fc fc-name
Description
This command explicitly defines the egress IEEE 802.1P (dot1p) bits marking for fc-name. When the
marking is set, all packets of fc-name that have either an IEEE 802.1Q or IEEE 802.1P encapsulation use the
explicitly defined dot1p-value. If the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P
encapsulated, the dot1p command has no effect.
The optional in-profile | dot1p-value out-profile dot1p-value structure added to the existing dot1p
command will add the capability to mark on an egress SAP the in and out of profile status via a certain dot1p
combination, similarly with the DE options.
The command with the additional structure 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 newly added structure must be specified.
When these commands are used the DE Bit or the equivalent field is left unchanged by the egress processing
if a tag exists. If a new tag is added, the related DE bit is set to 0.
When the previous command (dot1p dot1p-value) is used without the new structure, it means that the dot1p-
value is used for the entire forwarding class, same as before. The two versions of the command are mutually
exclusive.
