Configuring and Troubleshooting Line Card Interfaces

Configuring the 6-Port and 12-Port E3 Line Card Controller

This section provides basic information to configure an interface and to specify IP routing. You can also

enter other configuration commands and options, depending on the requirements of your system. To

configure the 6-port and 12-port E3 line cards interfaces, you must identify the router slot where the line

card is installed (for example, slot 7). Use the show diag EXEC command to verify that the system

recognizes the line card.

Router# show diag 2

SLOT 2 (RP/LC 2 ):6 Port Packet over E3

Router#

(Remainder of displayed text is omitted from example.)

If you know that there is more than one 6-port or 12-port E3 line card installed in the router, use the show

diag summary EXEC command to display the types of line cards that are installed in all the router slots.

The following output shows a 6-port E3 line card in slot 2 and a 12-port E3 line card in slot 6.

Router# show diag summ

SLOT 0 (RP/LC 0 ):1 Port Packet Over SONET OC-12c/STM-4c Single Mode

SLOT 1 (RP/LC 1 ):1 port SONET OC12 channelized to E3 Single Mode

SLOT 2 (RP/LC 2 ):6 Port Packet over E3 <<<<<----see E3 line card

SLOT 4 (RP/LC 4 ):4 Port Packet Over SONET OC-3c/STM-1 Single Mode

SLOT 6 (RP/LC 6 ):12 Port Packet over E3 <<<<<----see E3 line card

Router#

If you want to address a specific 6-port or 12-port E3 line card interface, refer to interface slot 2 or

interface slot 6, as shown in the previous output example.

If you want to address a specific port on the 6-port or 12-port E3 line card, refer to the router slot number

and one of the serial interface port numbers.

Based on the previous output example:

• To address the 6-port E3 line card, which has six ports, in slot 2, the valid port numbers are 0 through

5, inclusive. The serial interface slot/port configuration format range is 2/0 through 2/5.

• To address the 12-port E3 line card, which has twelve ports, in slot 6, the valid port numbers are 0

through 11, inclusive. The serial interface slot/port configuration format range is 6/0 through 6/11.

To configure a 6-port or 12-port E3 line card interface:

Step 1 Use the enable command to enter privileged EXEC mode. The system prompts you for a password if

one is set.

Router> enablepassword

Router#

Step 2 Enter configuration commands, one per line. Press Return after each configuration step unless otherwise

noted.

Step 3 Exit the privileged EXEC mode at any time and return to the Cisco IOS operation mode you want by

entering end or Ctrl-z at the prompt:

Router# end

Router>

Table 30 shows default values for the E3 serial interface configuration of an enabled line card. For more

information, see the configuration examples in this section.
