Syntax:
port-classify class <port-list> <0-7>
dei <port-list> <0-1>
dpl <port-list> <0-3>
dscp <port-list> disable/ enable
map <port-list> <0-7> <0-1> <0-7> <0-3>
pcp <port-list> <0-7>
tag <port-list> disable/ enable
Parameter :
class: Configure the default QoS class
<port-list>: available value is from switch physic port density,
format: 1,3-5
<0-7>: QoS class for frames not classified in any other way.
There is a one to one mapping between QoS class, queue and priority. A
QoS class of 0 (zero) has the lowest priority
dei: Configure the default DEI for untagged frames
<port-list>: available value is from switch physic port density,
format: 1,3-5
<0-1>: Drop Eligible Indicator. It is a 1-bit field in the VLAN tag
dpl: Configure the default DP level
<port-list>: available value is from switch physic port density,
format: 1,3-5
<0-3>: DP level for frames not classified in any other way
dscp: Configure DSCP based classification mode
<port-list>: available value is from switch physic port density,
format: 1,3-5
disable: Disable DSCP based classification
enable: Enable DSCP based classification
map: Configure the port classification map. This map is used when
port classification tag is enabled, and the purpose is to translate the
Priority Code Point (PCP) and Drop Eligible Indicator (DEI) from a
tagged frame to QoS class and DP level
<port-list>: available value is from switch physic port density,
