Conﬁguring the Fast Ethernet Interfaces*

Step 4 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.

Step 5 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*.”)

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:

•

Protocols you plan to route on each new interface

Internet protocol (IP) addresses if you plan to conﬁgure the interfaces for IP routing

Whether the new interfaces will use bridging

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 To prevent oversubscribing the FEIP, we recommend that you do not operate both interfaces on an FEIP in full-duplex mode.
