Port Configuration

Displaying Connection Status

You can use the Port Information or Trunk Information pages to display the current connection status, including link state, speed/duplex mode, flow control, and auto-negotiation.

Field Attributes (Web)

•Name – Interface label.

•Type – Indicates the port type. (100BASE-TX, 1000BASE-T, or SFP)

•Admin Status – Shows if the interface is enabled or disabled.

•Oper Status – Indicates if the link is Up or Down.

•Speed Duplex Status – Shows the current speed and duplex mode. (Auto, or fixed choice)

•Flow Control Status – Indicates the type of flow control currently in use. (IEEE 802.3x, Back-Pressure or None)

•Autonegotiation – Shows if auto-negotiation is enabled or disabled.

•Trunk Member1 – Shows if port is a trunk member.

•Creation2 – Shows if a trunk is manually configured or dynamically set via LACP.

1:Port Information only.

2:Trunk Information only.
