Other Port-based QoS settings are configured in port configuring mode under
prompt “(config-if)#”.
Entering “qos ?”, the following sub-commands will be shown.
(config)# qos ?
dscp DSCP Configuration
qcl QoS Control List Configuration
The first sub-command is for DSCP Configuration. The second sub-
command is for QCL(QoS Control List) Configuration.
Entering “qos dscp ?”, the following sub-commands will be shown.
(config)# qos dscp ?
classification-map Set DSCP ingress classification table
classification-mode Set DSCP ingress classification mode
egressremap Set DSCP egress remap table
map Set DSCP mapping table
translation Set global ingress DSCP translation table
trust Set w hether a specific DSCP value is trusted
qos dscp classification-map x y z
command is used to configure the
mapping of QoS class and Drop Precedence Level to in ternal DSCP value.
“
x
” is the QoS class with value 0~7. “
y
” is the Drop Precedence Level with
value 0~1. “
z
” is the dscp value 0~63.
Frames got a QoS class (either from port default or VLAN Tag or DSCP)
then it can map this QoS to internal DSCP. This internal DSCP then can
do another egress map to affect the DSCP value when the frame is sent
out. It could rewrite the egress DSCP value when Egress Rewrite is not
disable.
qos dscp classification-mode x
command is used to select the ingress
DSCP value f
or classification mode. “
x
” is the dscp value 0~63.
Select the DSCP value to enable its QoS Class to internal DSCP mapping
operation when Ingress Classify is “selected” in port “qos dscp
classification” command. And “
no qos dscp classification-mode x
” will
deselect the ingress DSCP value for classification mode.
qos dscp egressremap x y z
command is used to set DSCP egress
remap table. “
x
” is the dscp value 0~63. “
y
” is DPL(Drop Precedence
Level
) with value 0 or 1. “
z
” is the egress re-map dhcp value (0~63) for ths
DPL.
This command is used to set internal DSCP to egress DSCP value
remapping for DP level 0 or 1. It takes effect when port “qos dscp
egressremark” command is set.
qos dscp map x y z
command is used to set DSCP-Based QoS Ingress
Classifi
cation. “
x
” is the dscp value 0~63. “
y
” is the QoS class with
value 0~7. “
z
” is the Drop Precedence Level with value 0~1.
This command can configure the basic DSCP based QoS Ingress
