7.50 Unidirectional Operation

Description
The Unidirectional Operation parameter specifies the hardware capability. If a port fails at the
receive end, but can transmit data frames at the transmit end, it has the capability of performing
unidirectional operations. Otherwise, it does not have the capability of performing unidirectional
operations.
The unidirectional operation function specified in IEEE 802.3ah refers to whether the hardware
performs unidirectional operations if it has the capability of performing unidirectional
operations.
If the hardware does not have the capability of performing unidirectional operations, the
unidirectional operation function specified in IEEE 802.3ah is unavailable.
Impact on the System
After the Unidirectional Operation parameter is set to Enabled, IEEE 802.3ah packets are still
transmitted to the opposite end if the receive end is faulty.
Values
Valid Values
Enabled, Disabled
Configuration Guidelines
If the hardware has the capability of performing unidirectional operations and supports
unidirectional software operations, generally, set Unidirectional Operation to Enabled.
Relationship with Other Parameters
This parameter depends on whether the port hardware has the capability of performing
unidirectional operations.
