Remark Policy Forwarding Class Commands
de-mark
Syntax
[no] de-mark [force de-value]
Context
config>qos> remark-policy> fc
config> qos> access-egress> fc
config> qos> network> 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, 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.
Parameters
de-value —
Values
dot1p
Syntax
[no] dot1p dot1p-value
Context
config>qos>access-egress>fc
config> qos> network> egress> fc
config> qos> remark> fc>
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.
If DEI marking must be enabled using the de-mark command along with this command for the
command to take effect. When de-mark command is configured along with this command, then
the DEI bit is marked in the packet to indicate the profile of the packet. The DEI bit is marked to 0
