Displaying a DSCP Color Policy Conguration
To display the DSCP color policy conguration for one or all interfaces, use the show qos dscp-color-policy {summary
[interface] | detail {interface}} command in EXEC mode.
summary: Displays summary information about a color policy on one or more interfaces.
detail: Displays detailed color policy information on an interface
interface
: Enter the name of the interface that has the color policy congured.

Enabling QoS Rate Adjustment
By default, while rate limiting, policing, and shaping, the system does not include the Preamble, SFD, or the IFG elds. These elds are
overhead; only the elds 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
• Ethernet Type/Length: 2 bytes
• Payload: (variable)
• Cyclic redundancy check (CRC): 4 bytes
• Inter-frame gap (IFG): (variable)
You can optionally include overhead elds in rate metering calculations by enabling QoS rate adjustment.
QoS rate adjustment is disabled by default, and no qos-rate-adjust is listed in the running-conguration
