settings for the port. You can use this parameter to set the speed and duplex mode of a port. The possible settings are:
Ignore -This parameter i Indicates that the All setting does not apply to the Mode field. In other words, each port is set individually.
Auto -This parameter i Indicates the port is using Auto- Negotiation to set the operating speed and duplex mode. The actual operating speed and duplex mode of the port are displayed in parentheses (for example, “1000F” for 1000 Mbps full duplex mode) after a port establishes a link with an end node.
Auto (1000F) -This parameter i Indicates the port is configured for 1000Mbps operation in Auto-Negotiation mode.
1000/Full -This parameter i Indicates the port is configured for 1000Mbps operation in full-duplex mode.
100/Full -This parameter i Indicates the port is configured for 100Mbps operation in full-duplex mode.
10/Full -This parameter i Indicates the port is configured for 10Mbps operation in full-duplex mode.
1000/Half -This parameter i Indicates the port is configured for 1000Mbps operation in half-duplex mode.
100/Half -This parameter i Indicates the port is configured for 100Mbps operation in half-duplex mode.
10/Half -This parameter i Indicates the port is configured for 10Mbps operation in half-duplex mode.
When selecting a Mode setting, the following points apply:
When a twisted-pair port is set to Auto-Negotiation, the end node should also be set to 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.
The only valid setting for the SFP ports is Auto- Negotiation.
Flow Control - This parameter reflects the current flow control setting on the port. The switch uses a special pause packet to
