ef
Assigns the Expedited Forwarding PHB which has a corresponding DSCP value of 23.
dscp_num
Specifies a specific DSCP value as an integer from 0 through 31.
Usage
The differentiated services (DS) field of a packet contains six bits (0-5) that represent the differentiated
service code point (DSCP) value.
Five of the bits (1-5) represent the DSCP. Therefore, up to 32 (25) DSCPs can be assigned to the various
priorities. By default, they're all assigned to the lowest priority (best-effort).
For additional information on the NPU QoS functionality, refer to the System Administration Guide.
