Physical Interface Ethernet Smart Autosensing
Enabling and Disabling Smart Autosensing
You can enable and disable smart autosensing for the stack using the Smart Autosensing
window. If smart-autosensing is enabled on a 10BASE-T/100BASE-TX port, the port
monitors and detects the situation where auto negotiation has chosen 100Mbps but there
is an unacceptably high error rate. If the other end of the link also supports 10/100
auto negotiation, then this situation is corrected by forcing the link to 10Mbps.
1000BASE-SX ports do not support this command.
Smart Autosense will not operate on links that do not support auto-negotiation, or
on links where one end is at a fixed speed.
To access the window:
1. Click Device View on the Toolbar.
2. Select Physical Interface -> Ethernet -> Smart Autosensing in the Navigation
Tree.
3. The Smart Autosensing window is displayed.
4. From the Smart Autosensing: listbox, select Enabled or Disabled.
