Netgear M4100-D12G-POE+ (GSM5212P) - ProSAFE Gigabit L2+ Managed Switch ソフトウェアガイド

If you specify the interface, the command also displays the following information.

This command displays the global WRED settings for each CoS queue. If you specify the 
slot/port, the command displays the WRED settings for each CoS queue on the specified 
interface. 

This section describes the commands you use to configure QOS Differentiated Services 
(DiffServ).

You configure DiffServ in several stages by specifying three DiffServ components:

Class

a. Creating and deleting classes.

b.  Defining match criteria for a class. 

Interface

The slot/port of the interface. If displaying the global configuration, this output line is 
replaced with a Global Config indication.

Interface 
Shaping Rate

The maximum transmission bandwidth limit for the interface as a whole. It is independent 
of any per-queue maximum bandwidth value(s) in effect for the interface. This is a 
configured value.

Format

show interfaces random-detect [<slot/port>]

Mode

Privileged EXEC

Queue ID

An interface supports n queues numbered 0 to (n-1). The specific n value is 

platform-dependent.

WRED Minimum 
Threshold

The configured minimum threshold the queue depth (as a percentage) where WRED 
starts marking and dropping traffic.

WRED Maximum 
Threshold

The configured maximum threshold is the queue depth (as a percentage) above which 
WRED marks / drops all traffic.

WRED Drop 
Probability

The configured percentage probability that WRED will mark/drop a packet, when the 
queue depth is at the maximum threshold. (The drop probability increases linearly from 0 
just before the minimum threshold, to this value at the maximum threshold, then goes to 
100% for larger queue depths).
