Configuring the 12E/2FE Interfaces

PA-12E/2FE Ethernet Switch 10BASE-T and 100BASE-TX Port Adapter Installation and Configuration

6-6

Step 8 Reenable the interfaces. To do so, repeat the previous steps, but use the no shutdown

command in Step 4; then write the new conﬁguration to memory as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Router(config)# int fastethernet 1/0

Router(config-if)# no shutdown

Ctrl-Z

Router#

Router# copy running-config startup-config

[OK]

Router# show int fastethernet 1/0

FastEthernet1/0 is up, line protocol is up

Hardware is TSWITCH, address is 0000.0000.0000 (bia 0000.0000.0000)

Conﬁguring Interfaces

This section provides instructions for a basic conﬁguration: enabling a controller, specifying a bridge

group, and specifying IP routing. You might also need to enter other conﬁguration commands

depending on the requirements for your system conﬁguration and the protocols you plan to route on

the interface. For complete descriptions of conﬁguration subcommands and the conﬁguration

options available, refer to the documentation resources listed in the “For More Information” section

on page v.

Note If you plan to use a 12E/2FE interface to boot from a network (TFTP) on a Cisco 7200 series

router, ensure that the interface is conﬁgured for a loop-free environment, an IP address is conﬁgured

for the interface’s bridge-group virtual interface, and system boot image 11.2(10)P, 11.3(2)T, or

11.3(2)AA is installed on your router (use the show version command to view your router’s system

boot image).

If you plan to use a 12E/2FE interface to boot from a network (TFTP) on a Cisco uBR7246, ensure

that the interface is conﬁgured for a loop-free environment, an IP address is conﬁgured for the

interface’s bridge-group virtual interface, and system boot image 12.0(5)T is installed on your router

(use the show version command to view your router’s system boot image).

Before booting from the network server, use the bridge-group bridge-group number

spanning-disabled command to disable the Spanning-Tree Protocol conﬁgured on the interface to

keep the TFTP server from timing out and closing the connection.

For detailed information about booting from a network (TFTP), loading system images from a

network server, and conﬁguring the Spanning-Tree Protocol on your Cisco 7200 series router, refer

to the Conﬁguration Fundamentals Conﬁguration Guide and Bridging and IBM Networking

Conﬁguration Guide publications. See the “For More Information” section on page v for more

information.
