Port Information
The Port Information screen displays the port status, link state, the
communication speed and duplex mode, as well as the flow control and
communication speed and duplex mode, as well as the flow control and
802.1Q Trunk status. To change any of the port settings, use the Port
Configuration menu. The parameters shown in the following figure and

Description
Admin Status
Shows if the port is enabled or not.
Link Status
Indicates if the port has a valid connection to an external device.
Speed Status
Shows the port speed (1000M).
Duplex Status
Displays the current duplex mode.
Flow Control Status
Shows the flow control type in use. Flow control can eliminate
frame loss by “blocking” traffic from end stations connected
directly to the switch. Back pressure is used for half duplex and
IEEE 802.3x for full duplex.

802.1Q Trunk
Status
Status
Shows the VLAN trunk status for the port. A VLAN Trunk link
between two VLAN-aware switches will carry traffic from all
VLANs, allowing VLAN tagged frames to maintain their VLAN
ID across multiple switches. When enabled, a port joins all
configured VLANs and the untagged port VLAN ID (PVID) is set
to 4000, a reserved VLAN ID for trunk ports.
