Line Card and Route Processor Overview
The transmission speed of the Ethernet port is not user-configurable. You set the
speed through an autosensing scheme on the GRP which is determined by the
network that the Ethernet port is connected to. However, even at an auto-sensed
data transmission rate of 100 Mbps, the Ethernet port can only provide a usable
bandwidth of substantially less than 100 Mbps. You can expect a maximum usable
bandwidth of approximately 20 Mbps when using either the MII or
RJ-45 connection.
The following LEDs on the front panel indicate traffic status and port selection

LINK, COLL, TX, RX—Indicate link activity (LINK), collision detection
(COLL), data transmission (TX), and data reception (RX).
These LEDs are only used by the RJ-45 Ethernet connector and are
disabled when the MII Ethernet port is in use.
MII/RJ-45—Indicates which Ethernet port is selected.
