When autonegotiation is enabled, the Ethernet interface speed and duplex mode
are configured automatically. In this case,
Sections 2 and 3 in Table C-3 are not
applicable.
Fault Propagation
The LRSI-F-27 has a fault propagation option. This feature propagates the line
interface side error conditions to the Ethernet port.
Fault propagation disables the Ethernet interface link when a control signal is not
received from the line interface. The signal causes the Ethernet interface link to
fall hence loosing the Ethernet interface link integrity.
Configuring Fault Propagation
³ To enable or disable Fault propagation:
1. Go to the Modem Setup window in the terminal screen.
2. Select FAULT ETH INDICATION and set to Yes or No.
