The following sections describe the configurable features.
From the CLI "Unit Configuration," use the "Factory Default" command to restore the unit's default settings in the CLI, under Unit Configuration. This restores the card's default configuration and resets the default username and password.

Ethernet Port
If the Ethernet port is not used, it can be set to disabled via a console session or via iView², to effectively block all traffic on this port.
Packet Size
The Ethernet port can accommodate packets up to 1916 bytes.
Auto Negotiation
The IE-iMcV-T1-Mux/4 + Ethernet ships from the factory with Auto Negotiation enabled on the Ethernet port. In this mode, the port negotiates for speed, duplex and flow control.
Forcing the Speed, Duplex Mode, and Flow Control
The Ethernet port on the IE-iMcV-T1-Mux/4 + Ethernet can be selectively advertised or manually forced for 10 Mbps or 100 Mbps operation at Half- or Full-Duplex (i.e., 10 Mbps Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex, etc.). Flow control can also be enabled on the Ethernet port when the connecting equipment supports this. These features can be enabled through iView²/CLI.
Bandwidth Control
The IE-iMcV-T1-Mux/4 + Ethernet includes bi-directional bandwidth control in 32 Kbps increments (configurable via iView2).
FX LinkLoss and LFPT
During normal operation, link integrity pulses are transmitted by all point-to-point Ethernet devices. When an IE-iMcV-T1-Mux/4 + Ethernet receives valid link pulses, it knows that the device to which it is connected is up, and that the cable coming from that device is intact. The appropriate “LNK” (link) LED is lit to indicate this. However, these signals are not normally transmitted across a normal store and forward Ethernet bridge function. A failed Ethernet line on one end of the fiber link is not forwarded to the Ethernet port at the other end of the optical transport. A failed optical line is also not normally forwarded to the Ethernet port. The FX LinkLoss and LFPT functions are used to enable these features.
Both the LinkLoss and LFPT features are set to "Disabled" by default.
FX LinkLoss (FXLL)
FX LinkLoss is a link integrity monitoring feature that forwards fiber link faults to the RJ-45 DATA port to indicate that a fiber link fault has occurred. FX LinkLoss can be enabled in iView²/CLI.
