apply qosmark-mapping default
Provides access to default command mode for mapping internal PSC values to exit DSCP and EXP for this interface.
Syntax: apply qosmark-mapping default
no apply qosmark-mapping default
Description: When a packet enters an Avici router its DSCP or EXP values are mapped to IP or MPLS PSCs for internal treatment as the packet crosses the fabric. When the packet exits the router this internal mapping can be reversed such that PSC values are mapped to an exit DSCP or EXP value that is different from the entering value. You must enter a QoS mapping command mode in order to map PSC values to exiting DSCP or EXP values. QoS mapping can be configured globally or per interface using the apply command. Use of the apply command overrides any global default configuration for this interface.
Use the apply qosmark-mapping default command to enter the command mode for the mapping of PSC values to the DSCP or EXP value when exiting the router for this interface. When first entering this command mode, any changes made modify factory default settings for this interface.
Once in default Qosmark-mapping command mode, use the from psc to command to map IP and MPLS PSC values to exit DSCP and EXP values, respectively.
Once in the default Qosmark mapping command mode, you can disable exit-marking on any interface that uses default mappings by using the disable-marking command.
Use the no apply qosmark-mapping default command to reset any default mapping changes to the factory default values.
Use the qosmark-mapping default command in configuration command mode to set a default mapping globally for the router.
Factory Default: None.
Command Mode: Interface mode.
Example 1: The following example provides access to the command mode for configuring default PSC values to the DSCP or EXP value on the 1/1/1 interface:
router#config terminal
Enter configuration commands, one per line. End with CNTL/Z
router(config)#interface pos 1/1/1
router(config-if)#apply qosmark-mapping default
router(config-if)#
Example 2: The following command resets pos interface 1/1/1 PSC values to the DSCP or EXP value mappings to the factory default settings:
router#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface pos 1/1/1
router(config-if)#no apply qosmark-mapping default
router(config-if)#
