Description
This is the logical port number for this row.
Access ports are normally used to connect to end stations. Dynamic features like
Voice VLAN may add the port to more VLANs behind the scenes. Access ports
have the following characteristics:

Member of exactly one VLAN, the Port VLAN (Access VLAN), which by
default is 1

Accepts untagged and C-tagged frames

Discards all frames that are not classified to the Access VLAN

On egress all frames classified to the Access VLAN are transmitted
untagged. Other (dynamically added VLANs) are transmitted tagged
Trunk ports can carry traffic on multiple VLANs simultaneously, and are normally
used to connect to other switches. Trunk ports have the following characteristics:

By default, a trunk port is member of all VLANs (1-4095)

The VLANs that a trunk port is member of may be limited by the use of
Allowed VLANs

Frames classified to a VLAN that the port is not a member of are
discarded

By default, all frames but frames classified to the Port VLAN (a.k.a.
Native VLAN) get tagged on egress. Frames classified to the Port
VLAN do not get C-tagged on egress

Egress tagging can be changed to tag all frames, in which case only
tagged frames are accepted on ingress
Hybrid ports resemble trunk ports in many ways, but adds additional port
configuration features. In addition to the characteristics described for trunk ports,
hybrid ports have these abilities:

Can be configured to be VLAN tag unaware, C-tag aware, S-tag
aware, or S-custom-tag aware

Ingress filtering can be controlled

Ingress acceptance of frames and configuration of egress tagging can
be configured independently
