7210 SAS D, E, K OS Quality of Service Guide Page 357
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 —
Specifies the DEI value to use for this forwarding class.
Values 0 or 1
dot1p
Syntax [no] dot1p dot1p-value
Context config>qos>access-egress>fc
config> qos> network> egress> fc
Description
Platforms Supported: 7210 SAS-D.
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.
DEI marking can 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
to indicate in-profile/green packet and 1 to indicate out-of-profile/yellow packet. If the ‘force de-
value’ parameter is specified then the DEI bit is set to specified value for all packets.
If the no form of the command is executed then software will use the dot1p-in-profile and dot1p-
out-profile if configured, else it will use default values.
NOTE: The following rules are applied by software to determine the Dot1p values to when both
dot1p command and dot1p-in-profile and dot1p-out-profile command is specified:
1. If de-mark is not configured, then dot1p [in|out]-profile values are considered. Even if ‘dot1p
<val>’ is configured it is ignored and if ‘dot1p [in|out]-profile’ value is not configured then
default values are considered for that FC.
2. If de-mark is configured and if ‘dot1p’ value is configured then it is considered. Else if ‘dot1p
[in|out]-profile’ value is configured it is considered. In this case ‘dot1p <val>’ has the prece-
dence over ‘dot1p [in|out]-profile’.
Default no dot1p
Parameters dot1p-value —
Specifies the 802.1p value to set for in-profile frames in this forwarding class.
Values 0 — 7
