After you click the Edit (pencil) icon on the Networking > Ports > Physical Interface page, use the Ethernet Configuration - Add/Edit page to enable or disable the selected physical port, assign it to one or more VLANs, and configure the duplex mode.
1. Enter the following information:
• Name: The name of the physical port.
• Port Type: The type of the physical port, such as WAN, LAN, or DMZ.
• Mode: Choose either Access or Trunk mode for a LAN port, or choose Access for a WAN or DMZ port. By default, all ports are set to the Access mode.
– Access: All data going into and out of the
Access port is untagged. Access mode is recommended if the port is connected
to a single end
– Trunk: All data going into and out of the Trunk port is tagged. Untagged data coming into the port is not forwarded, except for the DEFAULT VLAN, which is untagged. Trunk mode is recommended if the port is connected to a VLAN-aware switch or router.
• Port: Click On to enable the port, or click Off to disable it. By default, all ports are enabled.
• VLAN: You can assign the physical port to VLANs.
– To assign the port to a VLAN, choose an existing VLAN from the Available VLAN list and click the right arrows. The associated VLANs appear in the list of VLAN.
– To release the port from a VLAN, choose a VLAN from the VLAN list and click the left arrows.
NOTE: A LAN port can be assigned to multiple VLANs, but an Access LAN port can only be assigned to one VLAN. A DMZ port must be assigned to a DMZ network.
NOTE: You can click the Create VLAN link to create new VLANs. For information on configuring VLAN, see Configuring a VLAN.
• Flow Control: Click On to control the flow on the port, or click Off to disable it.
NOTE: Gigabit Ethernet flow control is provided by a PAUSE frame mechanism. A congested port sends an XON PAUSE frame, which causes the source port to stop sending data until an XOFF PAUSE frame is received. For this mechanism to work, flow control must be enabled on the source port and the destination port. Even with flow control enabled, the packet drops may occur if the receiving port runs out of buffers.
• Speed: Choose one of these options: AUTO, 10M, 100M, and 1000M. The default is AUTO for all ports. The AUTO option lets the system and network determine the optimal port speed.
• Duplex: Choose either Half or Full based on the port speed setting. The default is Full Duplex for all ports.
– Full: The port supports transmissions between the device and the client in both directions simultaneously.
– Half: The port supports transmissions between the device and the client in only one direction at a time.
