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.
Remarking the inner DE bit is not supported based on the profile result of egress policing.
Value: 0 or 1
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, out, or exceed 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/exceed-profile packets– 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.
