Usage Information
If the average queue size is more than the maximum threshold of WRED, the packet is dropped. If the average
queue size is between the minimum and maximum threshold values, the decision to drop or queue the packet is
taken based on the packet drop probability. The probability that a packet is dropped depends on the minimum
threshold, maximum threshold, and mark probability denominator.
Example
Dell(conf-qos-policy-out) # wred weight 5
wred-profile
Create a WRED profile and name the profile.
Syntax
wred-profile
wred-profile-name
To remove an existing WRED profile, use the
no wred-profile
command.
Parameters
wred-profile-name
Enter your WRED profile name in character format (32 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 profiles.
Pre-defined Profiles: wred_drop, wred-ge_y, wred_ge_g, wred_teng_y, wred_teng_g.
