VLAN Access Ports and Trunk Ports

Using switch ports can minimize potential configuration errors. Switch ports also facilitate the
configuration of a VLAN by reducing the number of commands that you must enter. To
configure a port that is connected to an end user, use a switch port in access mode. To
configure a port that is connected to another switch, use a switch port in trunk mode.
In addition, to access mode and trunk mode, you can configure switch ports in general mode,
which is the default mode and does not restrict the configuration so you can configure the
port as needed.
The switch supports the following switch port modes, each with its own VLAN membership
rules:
• Access mode. In access mode, the following rules apply to switch ports:
- Ports belong to a single VLAN, for which the VID is the configured PVID.
- Ports are intended for end-point connections, which, in general, do not operate with
LANs and operate with tagged traffic.
- Ports accept both tagged and untagged traffic. (You cannot configurable whether the
ports accepts tagged or untagged traffic.)
- All egress traffic must be sent untagged.
- Ingress filtering is always enabled.
- Ports are intended for connecting end stations to the switch, especially when end
stations are incapable of generating VLAN tags.
• Trunk mode. In trunk mode, the following rules apply to switch ports:
- Ports can belong to as many VLANs as needed.
- Ports accept both incoming tagged and untagged traffic.
- All incoming untagged frames are tagged with the native VLAN as the VID.
- Egress frames are sent tagged for all VLANs other than the native VLAN. Frames that
belong to the native VLAN are sent without a VLAN tag.
- Ingress filtering is always enabled. If incoming frames are tagged correctly (that is,
tagged with a VID of one of the VLANs to which the port belongs), they are admitted.
- Ports are intended for connections between switches, for which the traffic is generally
tagged.
- If you configure a list with allowed VLANs, a trunk port becomes a member of VLANs
that are defined in the list with allowed VLANs.
• General mode. In general mode, the following rules apply to switch ports:
- By default, all ports are designated as general mode ports and belong to the default
VLAN.
- Ports conform to NETGEAR legacy switch behavior for switch ports.
