QoS DSCP Map
Description:
Set or show DSCP mapping table.
This table is used to map QoS class and DP level based on DSCP value.
DSCP value used to map QoS class and DPL is either translated DSCP value or
incoming frame DSCP value.
Syntax:
QoS DSCP Map [<dscp_list>] [<class>] [<dpl>]
Parameters:
<dscp_list>
: DSCP (0-63, BE, CS1-CS7, EF or AF11-AF43) list or 'all'
(default: Show DSCP ingress map table i.e. DSCP->(class, DPL))
<class>
: QoS class (0-7)
<dpl>
: Drop Precedence Level (0-1)
QoS DSCP Translation
Description:
Set or show global ingress DSCP translation table.
If port DSCP translation is enabled, translation table is used to translate incoming
frames DSCP value and translated value is used to map QoS class and DP level.
Syntax:
QoS DSCP Translation [<dscp_list>] [<trans_dscp>]
Parameters:
<dscp_list>
: DSCP (0-63, BE, CS1-CS7, EF or AF11-AF43) list or 'all'
(default: Show DSCP translation table)
<trans_dscp>
: Translated DSCP: 0-63, BE, CS1-CS7, EF or AF11-AF43
QoS DSCP Trust
Description:
Set or show trusted DSCP value which is used for QoS classification.
The DSCP value to be checked for trust is either translated value ifDSCP
translation is enabled for the ingress port or incoming frame DSCPvalue if
translation is disabled for the port. Trusted DSCP value is onlyused for QoS
classification.
Syntax:
QoS DSCP Trust [<dscp_list>] [enable|disable]
Parameters:
<dscp_list>
: DSCP (0-63, BE, CS1-CS7, EF or AF11-AF43) list or 'all'
enable
: Set DSCP as trusted DSCP
disable
: Set DSCP as un-trusted DSCP
(default: Show DSCP Trust status)
