If an error message displays on the console terminal, refer to the appropriate reference publication
for error message definitions. If you experience other problems that you are unable to solve, contact
a service representative for assistance.
Configuring the Fast Ethernet Interfaces*
If you installed a new FEIP or if you want to change the configuration of an existing interface, you
must enter configuration mode using the configuration command. If you replaced an interface that
was previously configured, the system recognizes the new interface and bring it up in its existing
configuration.
After you verify that the new FEIP is installed correctly (the enabled LED on each port adapter goes
on), use the privileged-level configure command to configure the new interfaces. Be prepared with
the information you need, such as the following:
•
•
•
For a summary of the configuration options available and instructions for configuring the interfaces
on the FEIP, refer to the appropriate configuration publications listed in the section "If You Need
More Information" on page 2.
The configure command requires privileged-level access to the EXEC command interpreter, which
usually requires a password. Contact your system administrator if necessary to obtain EXEC-level
access.
Each 100BASE-TX or 100BASE-FX interface on an FEIP can be configured at 100 Mbps, half
duplex or full duplex, for a maximum aggregate bandwidth of 200 Mbps.
Caution
FEIP in full-duplex mode.
28 Fast Ethernet Interface Processor (FEIP) Installation and Configuration
If an enabled LED still fails to go on, remove the FEIP and try installing it in another
available interface processor slot.
If the enabled LED goes on when the FEIP is installed in the new slot, suspect a failed
backplane port in the original interface processor slot.
If the enabled LED still fails to go on, but other LEDs on the FEIP go on to indicate
activity, proceed to Step 5 to resume the installation checkout and suspect that the enabled
LED on the FEIP has failed.
If no LEDs on the FEIP go on, suspect that the FEIP is faulty.
If the enabled LED still does not go on, do not proceed with the installation. Contact a
service representative to report the faulty equipment and obtain further instructions.
Use the show interfaces or show controllers cbus command to verify the status of the
FEIP's interfaces. (If the interfaces are not configured, you must configure them using the
procedures in the section "Configuring the Fast Ethernet Interfaces*.")
Protocols you plan to route on each new interface
