Vigor2130 Series User's Guide
If flow control is enabled by checking Configured box,
both parties can send PAUSE frame to the transmitting
device(s) if the receiving port is too busy to handle. If not,
there will be no flow control in the port. It drops the packet
if too much to handle.
Current Rx: indicates whether pause frames on the port are
obeyed.
Current Tx: indicates whether pause frames on the port are
transmitted.
This module offers 1518~9600 (Bytes) length to make the
long packet for data transmission.
There are two modes for you to choose when excessive
collision happened in half-duplex condition.
Discard - It determines whether the MAC drops frames
after an excessive collision has occurred. If yes, a frame is
dropped after excessive collision. This is IEEE Standard
802.3 half-duplex flow control operation.
Restart - It determines whether the MAC retransmits
frames after an excessive collision has occurred. If set, a
frame is not dropped after excessive collisions, but the
backoff sequence is restarted. This is a violation of IEEE
Standard 802.3, but is useful in non-dropping half-duplex
flow control operation.
The Configured column allows for changing the power
savings mode parameters per port.
Disabled: All power savings mechanisms disabled.
ActiPHY: Link down power savings enabled.
PerfectReach: Link up power savings enabled.
Enabled: Both link up and link down power savings
enabled.
