Honoring the Incoming DEI Value

To honor the incoming DEI value, you must explicitly map the DEI bit to a Dell Networking OS drop precedence.

Precedence can have one of three colors.

Precedence	Description
Green	High-priority packets that are the least preferred to be dropped.
Yellow	Lower-priority packets that are treated as best-effort.
Red	Lowest-priority packets that are always dropped (regardless of congestion status).

Honor the incoming DEI value by mapping it to the Dell Networking OS drop precedence. INTERFACE mode dei honor {0 | 1} {green | red | yellow} You may enter the command once for 0 and once for 1. Packets with an unmapped DEI value are colored green.

Example of Viewing DEI-Honoring Configuration

To display the DEI-honoring configuration, use the show interface dei-honor [interface slot/port | linecard number port-set number] in EXEC Privilege mode.
