Default Configuration
WRED queue management policy is disabled by default. Tail-drop queue
management policy is enabled by default. The threshold for invoking tail-
drop behavior when WRED is disabled is approximately 1/2 of the remaining
free packet buffer in the switch.
Command Mode
Interface Configuration (physical or port-channel) mode, Interface Range
mode, or Global Configuration mode
User Guidelines
When used on a port-channel, this command will override the settings on the
individual interfaces that are part of the port channel. Removing an interface
from the port channel restores the individual interface settings.
This command can be used in Interface Range mode.
Use the
cos-queue min-bandwidth
scheduler bandwidth percentage guarantee for the CoS queues.
Use the
show interfaces random-detect
configuration, including ECN configuration.
Use the

other than default green color.
The drop probability scale supports values in the range 0-10% and the discrete
values 25%, 50%, 75%, and 100%. Other values are truncated to the next lower
value by the hardware.
N1500 Series Switches
N1500 Series switches support a simple RED capability. The N1500 Series
switch does not support configuration of the maximum threshold nor can the
threshold or drop probability be configured for non-TCP traffic. Only the
minimum threshold (min-thresh) and drop probability (drop-prob-scale) may
be configured for the TCP colors green/yellow/red. The maximum threshold
may not be configured nor can the threshold or drop probability be
configured for non-TCP traffic. ECN capability is supported.
