Service Egress QoS Policy Forwarding Class Commands
dot1p-inner in the policy, that is, 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).
The no form of the command sets the inner IEEE 802.1P or IEEE 802.1Q priority bits to 0.
This command is supported on FP2 and higher based hardware, and is otherwise ignored.
Default
0
Parameters dot1p-inner dot1p-value — Specifies the 802.1p value to set for in-profile frames in this forwarding class.
Values
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
dot1p-outer
Syntax [no] dot1p-outer {dot1p-value | in-profile dot1p-value out-profile dot1p-value}
Context config>qos>sap-egress>fc
Description
This command explicitly defines the egress outer or single 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 outer or single IEEE 802.1Q or
IEEE 802.1P encapsulation on a qinq or a dot1p SAP, respectively, will use the explicitly defined dot1p-
value. If the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P encapsulated, this command
has no effect.
The optional in-profile | dot1p-value out-profile dot1p-value parameters on the dot1p-outer command adds
the capability to mark the in and out of profile status on an egress qinq or dot1p 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 a (single or outer) tag exists. If a new 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(-outer) 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 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 no form of the command sets the IEEE 802.1P or IEEE 802.1Q priority bits to 0.
This command is supported on FP2 and higher based hardware, and is otherwise ignored.
