When you enable wred ecn, and the number of packets in the queue is between

the minimum threshold and the maximum threshold, one of the following three

scenarios can occur:

When you enable wred ecn, and the number of packets in the queue is above the

maximum threshold, packets are dropped based on the drop probability. This

behavior is the identical treatment a packet receives when WRED is enabled

without ECN configured on the router.

wred-profile

wred-profile

Create a WRED profile and name the profile.

wred-profile wred-profile-name

To remove an existing WRED profile, use the no wred-profile command.

wred-profile-

The five pre-defined WRED profiles. When you configure a new profile, the

minimum and maximum threshold defaults to predefined wred_ge_g values.

If green profile is applied, default yellow also take effect and vice-versa.

CONFIGURATION

This guide is platform-specific. For command information about other platforms,

refer to the relevant Dell Networking OS Command Line Reference Guide.

The following is a list of the Dell Networking OS version history for this command.

Quality of Service (QoS)

If the transmission endpoints are ECN-capable and traffic is congested, and the

WRED algorithm determines that the packet should have been dropped based

on the drop probability, the packet is transmitted and marked so the routers

know the system is congested and can slow transmission rates.

If neither endpoint is ECN-capable, the packet may be dropped based on the

WRED drop probability. This behavior is the identical treatment that a packet

receives when WRED is enabled without ECN configured on the router.

— creates a WRED profile and name that profile.

Enter your WRED profile name in character format (16

character maximum). Or use one of the pre-defined WRED

profile names. You can configure up to 26 WRED profiles

plus the five pre-defined profiles, for a total of 31 WRED

Pre-defined Profiles: wred_drop, wred-ge_y, wred_ge_g,

wred_teng_y, wred_teng_g.
