148 CHAPTER 7: CONFIGURING VLANS
■ Access — Indicates a port belongs to a single untagged VLAN.
When a port is in Access mode, the packet types which are
accepted on the port cannot be designated. Ingress filtering cannot
be enabled or disabled on an access port.
■ Trunk — Indicates the port belongs to VLANs in which all ports are
tagged, except for one port that can be untagged.
■ PVID — Assigns a VLAN ID to untagged packets. The possible values
are 1-4094. VLAN 4095 is defined as per standard and industry
practice as the Discard VLAN. Packets classified to the Discard VLAN
are dropped.
■ Frame Type — Specifies the packet type accepted on the port. The
possible field values are:
■ Admit Tag Only — Only tagged packets are accepted on the port.
■ Admit All — Both tagged and untagged packets are accepted on
the port.
■ Ingress Filtering— Indicates whether ingress filtering is enabled on
the port. The possible field values are:
■ Enable — Enables ingress filtering on the device. Ingress filtering
discards packets that are defined to VLANs of which the specific
port is not a member.
■ Disable — Disables ingress filtering on the device.
