Device Configuration 5 - 23
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.
Type Displays the physical port type.
Description Displays an administrator defined description for each listed port.
Admin Status A green check mark defines the port as active and currently enabled with the profile. A
red “X” defines the port as currently disabled and not available for use. The interface
status can be modified with the port configuration as required.
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.
