30 Second-Generation Fast Ethernet Interface Processor (FEIP2) Installation and Conﬁguration

Conﬁguring the Fast Ethernet Interfaces

Step 4 If an enabled LED still fails to go on, remove the FEIP2 and try installing it in another

available interface processor slot.

If the enabled LED goes on when the FEIP2 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 FEIP2 go on to indicate

activity, proceed to Step 5 to resume the installation checkout and suspect that the enabled

LED on the FEIP2 has failed.

If no LEDs on the FEIP2 go on, suspect that the FEIP2 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

FEIP2’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 Fast Ethernet (FE) interface 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 FE interface is installed correctly (the enabled LED 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 FE

interfaces on the FEIP2, 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.

Note Each FE interface on an FEIP2 can be conﬁgured at 100 Mbps, half duplex, for a maximum

aggregate bandwidth of 200 Mbps per pair. Each FE interface on an FEIP2 can also be conﬁgured

at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 400 Mbps per pair. Further, one

FE interface can be conﬁgured at 100 Mbps, half duplex, while the other FE interface can be

conﬁgured at 200 Mbps, full duplex, for a maximum aggregate bandwidth of 300 Mbps per pair.
