When selecting a setting, note the following:
When a twisted pair port is set to Auto-Negotiation, the default
setting, the end node should also be using Auto-Negotiation to
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.
Allied 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.
The 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 uses flow control. This is the default setting for all
ports on the switch.
Disabled - The port does not use flow control.
MAC Address
The port’s MAC address. This setting can not be changed.
