Figure 5-146 Device Overrides - Interface Ethernet Port screen
7. Refer to the following to review port status and assess whether an override is warranted:
Name Displays the physical port name reporting runtime data and statistics. Supported ports
vary depending on the supported models.
Type Displays the physical port type. Copper is used on RJ45 Ethernet ports and Optical
materials are used on fiber optic gigabit Ethernet ports.
Description Displays an administrator defined description for each listed access point 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 (as defined within
the Ethernet Port Basic Configuration screen). If Access is selected, the listed 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.
