6. To edit an access point profile’s port configuration, select it from amongst those displayed and
then select the Edit button. The Ethernet port Basic Configuration screen displays by default.
FIGURE 13 Ethernet Ports - Basic Configuration screen
Mode Displays the profile’s current switching mode as either Access or Trunk. If Access is listed, the port
accepts packets only from the native VLAN. Frames are forwarded out the port untagged with no
802.1Q header. All frames received on the port are expected as untagged and mapped to the
native VLAN. If set to Trunk, the port allows packets from a list of VLANs added to the trunk. A port
configured as Trunk supports multiple 802.1Q tagged VLANs and one Native VLAN which can be
tagged or untagged.
Native VLAN Lists the numerical VLAN ID (1 - 4094) set for the native VLAN. The native VLAN allows an Ethernet
device to associate untagged frames to a VLAN when no 802.1Q frame is included in the frame.
Additionally, the native VLAN is the VLAN untagged traffic is directed over when using a port in trunk
mode.
Tag Native VLAN A green check mark defines the native VLAN as tagged. A red “X” defines the native VLAN as
untagged. When a frame is tagged, the 12 bit frame VLAN ID is added to the 802.1Q header so
upstream Ethernet devices know which VLAN ID the frame belongs to. The device reads the 12 bit
VLAN ID and forwards the frame to the appropriate VLAN. When a frame is received with no 802.1Q
header, the upstream device classifies the frame using the default or native VLAN assigned to the
Trunk port. A native VLAN allows an Ethernet device to associate untagged frames to a VLAN when
no 802.1Q frame is included in the frame.
Allowed VLANs Displays the VLANs allowed to send packets over the listed port. Allowed VLANs are only listed when
the mode has been set to Trunk.
