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

Issue 02 (2011-06-30)
Description
Indicates that the port disables the flow control function.
Indicates that the port only transmits flow control frames, but
does not process the received flow control frames.
Indicates that the port can transmit PAUSE frames and
process the received PAUSE frames.
Indicates that the symmetric/dissymmetric flow control mode
is decided by the auto-negotiation result.
