Enum PortMode 

pub enum PortMode {
    Access {
        vlan: u16,
    },
    Trunk {
        allowed: VlanSet,
        native: Option<u16>,
    },
}

How a port treats VLAN tags on the way in and on the way out.

The default is PortMode::transparent: every VLAN passes and tags are left exactly as they arrived, which is how the switch behaves before any port is configured.

Variants

Access

An edge port belonging to a single VLAN.

Frames arriving untagged are treated as belonging to vlan; a frame tagged with vlan is also accepted, and any other tag is dropped as misconfiguration. Frames leaving are always untagged, so the station behind the port never sees 802.1Q at all.

Fields

vlan: u16

Trunk

An uplink carrying several VLANs, tagged.

A frame arriving tagged is accepted if its VLAN is in allowed. A frame arriving untagged belongs to native, if set, and is dropped otherwise. On the way out, frames are tagged, except those on the native VLAN which leave untagged.

Fields

allowed: VlanSet

native: Option<u16>

Implementations

impl PortMode

pub fn transparent() -> PortMode

Pass every VLAN through untouched, treating untagged frames as VLAN 0.

This is the default, and it makes the switch behave as though VLANs were not modelled at all.
