CHAPTER 9: PORT MIRRORING AND SETUP

PORT SETUP

MULTILINK ML810 MANAGED EDGE SWITCH – INSTRUCTION MANUAL

9–5

9.3.2

Flow Control

The 

flow

 setting is disabled by default. In this case, the port will not generate flow control 

packets and drops received flow control packets. If the 

flow

 setting is enabled, the port 

uses 802.3x Link Layer Flow Control, generates flow control packets, and processes 
received flow control packets.

NOTE

Note

With the port speed set to auto (the default) and flow control set to enabled; the switch 
negotiates flow control on the indicated port. If the port speed is not set to auto, or if flow 
control is disabled on the port, then flow control is not used.
Use the 

flowcontrol

 command to set flow control:

flowcontrol

 xonlimit=<value> xofflimit=<value>

where  

xonlimit

 can be from 3 to 127 (default value is 4) and 

xofflimit

 ranges from 3 to 

127 (default value is 6).

9.3.3

Back Pressure

The 

backpressure

 command disables/enables back pressure based flow control 

mechanisms. The default state is disabled. When enabled, the port uses 802.3 Layer 2 back 
off algorithms. Back pressure based congestion control is possible only on half-duplex, 10-
Mbps Ethernet ports. Other technologies are not supported on the MultiLink ML810 
Managed Edge Switch.

backpressure

 rxthreshold=<value>

where the 

rxthreshold

 value can be from 4 to 30 (default is 28).

Back pressure and flow control are used in networks where all devices and switches can 
participate in the flow control and back pressure recognition. In most networks, these 
techniques are not used as not all devices can participate in the flow control methods and 
notifications. Alternately, QoS and other techniques are widely used today.
In the example below, the MultiLink ML810 Managed Edge Switch is set up with flow 
control and back pressure.
