Allied Telesis AT-S79 manual Flow Control

Chapter 16: Port Configuration

prevent a duplex mode mismatch. A switch port using Auto- Negotiation defaults to half-duplex if it detects that the end node is not using Auto-Negotiation. This can result in a mismatch if the end node is operating at a fixed duplex mode of full-duplex. To avoid this problem when connecting an end node with a fixed duplex mode of full-duplex to a switch port, disable Auto-Negotiation on the port and set the port’s speed and duplex mode manually.

ˆAllied Telesyn does not recommend manually setting a 10/100/ 1000Base-T twisted pair port to either 1000 Mbps full duplex or 1000 Mbps half duplex. For 1000 Mbps operation, Allied Telesyn recommends setting the port to Auto-Negotiation.

ˆThe only valid setting for an optional SFP port is Auto-Negotiation.

Flow Control

The current flow control setting on the port. The switch uses a special pause packet to notify the end node to stop transmitting for a specified period of time. The possible values are:

Enabled - The port is allowed to use flow control. This is the default setting for all ports on the switch.

Disabled - The port does not use flow control.
