Expiration time has not yet expired since the last determination (if there was one),
or since UDLD began running on the port, so that the state is not yet determined.
- Bidirectional—Traffic sent by the local device is received by its neighbor, and
traffic from the neighbor is received by the local device.
- Undetermined—The state of the link between the port and its connected port cannot
be determined either because no UDLD message was received or the UDLD

is undetermined in aggressive mode.
