pause packet notifies the end node to stop transmitting for a
specified period of time. The possible settings are:
Auto - The port uses flow control if it detects that the end node is
using it.
Disabled - No flow control on the port. This is the default.
Enabled - Flow control is activated.
For further information about flow control, refer to Chapter 6,
“Port Parameters,” in the AT-S63 Management Software Menus
Interface User’s Guide.
Back Pressure
Use this parameter to set back pressure on a port. This option only
appears for ports operating in half-duplex mode. A switch port
uses back pressure to control the flow of ingress packets. The
possible settings are:
Enabled - Back pressure is enabled.
Disabled - Back pressure is disabled. This is the default.
For further information about back pressure, refer to Chapter 6,
“Port Parameters,” in the AT-S63 Management Software Menus
Interface User’s Guide.
Flow Control/Back Pressure Limit
Use this parameter to specify the maximum number of ingress
packets that a port receives within a one second period before
initiating flow control or back pressure. The range is 1 to 7935
cells. The default is 561.
The following three parameters allow you to set rate limiting, the
maximum number of ingress packets a port accepts each second.
Packets exceeding the threshold are discarded.
Broadcast Rate Limit
Use this parameter to enable or disable ingress broadcast packet
limits and specify a rate limit for the ingress broadcast packets.
The possible settings are:
Enabled - Broadcast packet ingress rate limiting is enabled.
Disabled - Broadcast packet ingress rate limiting is disabled. This is
the default.
You can also set the rate limit in packets per second. The range is
0 to 262143. The default is 262143.
