What It Means The M10i router craft interface command output displays the LED status of the
master Routing Engine, indicating whether the
OK and Fail LEDs are on or off. It also
displays that the backup Routing Engine is active.
The M20 router craft interface command output displays the LED status of the
master Routing Engine, indicating whether the
OK and Fail LEDs are on or off.
The M40e and M160 router craft interface command output also displays the LED
status of both the master and backup host modules that include the master and
backup Routing Engines. By default, the master host module (
Host 0) has
components installed in slots
RE0 and MCS0; the backup host module (Host 1) has
components installed in slots
RE1 and MCS1.
The T640 routing node craft interface command output indicates that
RE0 is the
master Routing Engine, and that it is active. The status under the backup Routing
Engine (
RE1) has no indicators.
