packet types which are accepted on the port cannot be designated. Ingress filtering is always enabled for
ports in Access mode.

Trunk —
Indicates the port belongs to VLANs in which all VLANs are tagged, except for one VLAN that is
untagged.

.
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.
