Chapter 3: Software Description
• Port/Trunk: The port number of the port or the ID of a trunk.
• VLAN Aware Enabled: VLAN aware ports are able to use VLAN tagged frames
to determine the destination VLAN of a frame. (Default: Enabled)
• VLAN aware ports will strip the VLAN tag from received frames and insert the
tag in transmitted frames (except for the PVID). VLAN unaware ports will not
strip the tag from received frames or insert the tag in transmitted frames.
• Ingress Filtering Enabled: If enabled, incoming frames for VLANs that do not
include this ingress port in their member set will be discarded.
(Default: Disabled)
• Packet Type: Sets the interface to accept all frame types, including tagged or
untagged frames, or only tagged frames. (Default: All) If the Packet Type is set
to “All,” the port can accept incoming tagged and untagged packets. Any
received packets that are untagged are assigned to the default VLAN. Any
tagged packets will be dropped unless the port is a member of the VLAN identi-
fied by the VLAN tag in the packet. If the Packet Type is set to “Tagged Only,”
the port will drop untagged packets and will only receive tagged packets.
Tagged packets will be dropped unless the port is a member of the VLAN iden-
tified by the VLAN tag in the packet. Switches should be connected to each
other with the Packet Type set to “Tagged Only.”
• PVID: The PVID (Port VLAN ID) is associated with untagged, ingress packets. It is
assigned to untagged frames received on the specified interface. The PVID has
no effect on ports that have Packet Type set to “Tagged Only.” (Default PVID: 1)
It is not possible to remove a port from VLAN 1 unless its PVID has been
changed to something other than 1. Outgoing packets are tagged unless the
packet’s VLAN ID is the same as the PVID. When the PVID is set to “None,” all
outgoing packets are tagged.
NOTE: If you select “Tagged Only” mode for a port, we recommend setting the
PVID to “None” as the standard configuration.
