Service SAP QoS Policy Command Reference
Parameters dot1p-value — Specifies the 802.1p value to set for in-profile frames in this forwarding class.
in-profile dot1p-value — Specifies the 802.1p value to set for in-profile frames in this forwarding
out-profile dot1p-value — specifies the 802.1p value to set for out-profile frames in this
dot1p-outer
Syntax [no] dot1p-outer {dot1p-value | in-profile dot1p-value out-profile dot1p-value [exceed-
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 [exceed-profile dot1p-value] parameters
on the dot1p-outer command adds the capability to mark the in, out, and exceed 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, out, and exceed 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 out-profile keyword must be specified, however,
exceed-profile is optional. If the optional exceed-profile dot1p-value is not included, any exceed
profile traffic will be marked with the same dot1p value as configured for the out of profile traffic.
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,
out, or exceed profile status may be indicated via the setting of the DE bit setting if the de-mark(-
outer) command is used. The DE value used for exceed profile is the same as that used for out of
profile.
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.
