Honoring the Incoming DEI Value
To honor the incoming DEI value, you must explicitly map the DEI bit to an Dell Networking OS drop
precedence; precedence can have one of three colors:
Marking Egress Packets with a DEI Value
On egress, you can set the DEI value according to a different mapping than ingress (see Honoring the
Incoming DEI Value).
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).
Task Command Syntax Command Mode
Honor the incoming DEI value by mapping it to an
Dell Networking OS drop precedence. You may
enter the command once for 0 and once for 1.
Packets with an unmapped DEI value are colored
green.
