Ethernet Management

Overview

Ethernet management API provides functions to manage the Ethernet network interface low level status. The caller of these functions can:

  • raise carrier ON or carrier OFF management events

  • raise VLAN enabled or VLAN disabled management events

Typically the carrier OFF event would be generated by the Ethernet device driver when it notices that the Ethernet cable is disconnected. The carrier ON event would be generated if the Ethernet device driver notices that the Ethernet cable is re-connected.

Currently the VLAN events are generated by the Ethernet L2 layer when a specific VLAN tag is either enabled or disabled.

The user application can monitor these events if it needs to act when the corresponding status changes.
