5.3.3 802.1Q Port
This tab page configures 802.1Q VLAN port parameters:
Port: Specifies the port to be configured.
PVID: Each port can have only one Port VLAN ID (PVID), an untagged Ethernet package will
be tagged a VID of PVID when arriving at the port. The default PVID is 1 for each port.
Link Type: Can choose Hybrid (by default), Access or Trunk from this drop-down list.
Access: An access port can belong to only one VLAN, and is generally used to connect
user PCs. Tag is deleted when transmitting packets.
Trunk: A trunk port can belong to more than one VLAN. It can receive/send packets
from/to multiple VLANs, and is generally used to connect another switch. A trunk port can
belong to multiple VLANs, but it can only be configured as untagged in one VLAN. All
packages are tagged, except when an egress package is in a VLAN group with VID the
same as PVID.
Hybrid: A hybrid port can belong to more than one VLAN. It can receive/send packets
from/to multiple VLANs, and can be used to connect either a switch or user PCs. A
Hybrid port is similar to a Trunk port, except it leaves the user a flexibility of configuring
each port as tagged or untagged.
Frame Type: Chooses how the port accepts Ethernet package. When Admit All is selected,
the port accepts all ingress packages; while Admit Only Tagged accepts only tagged
packages, and discards untagged ones.
VLAN Ingress Filter: When enabled, an Ethernet package is discarded if this port is not a
member of the VLAN with which this package is associated. When disabled (by default), all
packages are forwarded in accordance with the 802.1Q VLAN bridge specification.
The lower part of this tab page lists the status of all ports.
