7.4 Autonegotiation Flow Control Mode (Ethernet Port
Attribute)
Description
The
Autonegotiation Flow Control Mode (Ethernet Port Attribute)
specifies the flow control
mode adopted when an Ethernet port works in auto-negotiation mode.
Impact on the System
If the negotiation result is to enable the flow control function, the PAUSE frame is transmitted
to the upstream port.
Values
Valid Values
Default Value
Disabled, Enable Dissymmetric Flow
Control, Enable Symmetric Flow Control,
Enable Symmetric/Dissymmetric Flow
Control
Disabled
The following table lists the description of each value.
Value
Description
Disabled
Indicates that the port disables the flow control function.
Enable Dissymmetric Flow
Control
Indicates that the port only transmits flow control frames, but
does not process the received flow control frames.
Enable Symmetric Flow
Control
Indicates that the port can transmit PAUSE frames and
process the received PAUSE frames.
Enable Symmetric/
Dissymmetric Flow Control
Indicates that the symmetric/dissymmetric flow control mode
is decided by the auto-negotiation result.
Configuration Guidelines
Generally, set this parameter to
Enable Symmetric/Dissymmetric Flow Control
, unless
otherwise specified.
