32 Fast Ethernet Interface Processor (FEIP) Installation and Configuration
Configuring the Fast Ethernet Interfaces*
The RJ-45 connection is the default for FEIP-2TX (or SC for FEIP-2FX). To change to an MII
connection and then verify it, use the following series of commands, including the media-type
configuration command:
Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# int fa 3/0/0
Router(config-if)# media-type mii
Ctrl-z
Router#
Router# sh int fa 3/0/0
FastEthernet3/0/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII
(display text omitted)
Use the media-type 100 configuration command to return the interface to its defaultstate for RJ-45
or SC (fiber-optic) connections.
Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new
interface or all interfaces, and use the ping command to check connectivity.
Using show Commands to Verify the FEIP Status
The following steps use show commands to verify that the new interfaces are configured and
operating correctly.
Step 1 Use the show version command to display the system hardware configuration. Ensure
that the list includes the new interfaces.
Step 2 Displayall the current interface processors and their interfaces with the show controllers
cbus command. Verify that the new FEIP appears in the correct slot.
Step 3 Specify one of the new interfaces with the show interfaces type slot/adapter/interface
commandand verify that the first line of the display specifies the interface with the correct
slot number.Also verify that the interface and line protocol are in the correct state: up or
down.
Step 4 Display the protocols configured for the entire system and specific interfaces with the
show protocols command. If necessary, return to configuration mode to add or remove
protocol routing on the system or specific interfaces.
Step 5 Display the running configuration file with the show running-config command. Display
the configuration stored in NVRAM using the show startup-config command. Verify
that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is
not functioning properly,ensure that the network interface is properly connected and terminated. If
you still have problems bringing the interface up, contact a service representative for assistance.
