This command is required only if an 802.1p priority is not already assigned to the specified

codepoint in the DSCP Policy table.

Valid values for a DSCP codepoint are as follows:

• A binary value for the six-bit codepoint from 000000 to 111111.

• A decimal value from 0 (low priority) to 63 (high priority) that corresponds to a binary

DSCP bit set

• An ASCII standard (hexadecimal) name for a binary DSCP bit set

When the switch applies the specified DSCP policy to a packet, the priority determines

the packet's queue in the outbound port to which it is sent. If the packet leaves the switch

on a tagged port, it carries the 802.1p priority with it to the next downstream device.

For IP packets, the DSCP will be replaced by the codepoint specified in this command.

Default: No-override for most codepoints.
