Enabling QoS Rate Adjustment
By default while rate limiting, policing, and shaping, Dell EMC Networking OS does not include the Preamble, SFD, or the IFG fields. These
fields are overhead; only the fields from MAC destination address to the CRC are used for forwarding and are included in these rate
metering calculations.
The Ethernet packet format consists of:
Preamble: 7 bytes Preamble
Start frame delimiter (SFD): 1 byte
Destination MAC address: 6 bytes
Source MAC address: 6 bytes
