NETGEAR Understanding Traffic Shaping Switch Features in Managed Networking

NETGEAR 7000 Series Managed Switch Administration Guide Version 7.2

Example #5: Set CoS Trust Mode of an Interface

(Netgear Switch) (Config)#classofservice trust ?

dot1p	Sets the Class	of Service Trust Mode of an Interface
ip-dscp	to 802.1p.	of Service Trust Mode of an Interface
	Sets the Class
	to IP DSCP.
(Netgear Switch) (Config)#classofservice trust dot1p ?
<cr>	Press Enter to	execute the command.

(Netgear Switch) (Config)#classofservice trust dot1p

Note: The Traffic Class value range is <0-6> instead of <0-7> because queue 7 is reserved in a stacking build for stack control, and is therefore not configurable by the user.

Traffic Shaping

This section describes the Traffic Shaping feature.

Traffic shaping controls the amount and volume of traffic transmitted through a network. This has the effect of smoothing temporary traffic bursts over time.

CLI Example

Use the traffic-shapecommand to enable traffic shaping by specifying the maximum transmission bandwidth limit for all interfaces (Global Config) or for a single interface (Interface Config).

The <bw> value is a percentage that ranges from 0 to 100 in increments of 5. The default bandwidth value is 0, meaning no upper limit is enforced, which allows the interface to transmit up to its maximum line rate.

The bw value is independent of any per-queue maximum bandwidth value(s) in effect for the interface and should be considered as a second-level transmission rate control mechanism that regulates the output of the entire interface regardless of which queues originate the outbound traffic.
