Configuring the SM-1-STM1

To continue your SM-1-STM1 service module installation, you must configure the STM-1 interface.

This chapter contains the following sections:

•Configuring the Interface

•Checking the Configuration

Configuring the Interface

After you verify that the new SM-1-STM1 is installed correctly (the ENABLED LED is lit), use the privileged-level configure command to configure the new interface. Have the following information available:

•Protocols you plan to route on each new interface

•IP addresses, if you plan to configure the interfaces for IP routing

•Bridging protocols you plan to use

If you installed a new SM-1-STM1, or to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a SM-1-STM1 that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

For a summary of the configuration options available and instructions for configuring interfaces on a SM-1-STM1, refer to the appropriate configuration publications listed in the "Related Documentation" section on page 5.

This section contains the following subsections:

•Shutting Down an Interface

•Performing a Basic Interface Configuration

•Configuring the AU-3s and TUG-3s of a SM-1-STM1

•Configuring an E1 Unframed Channel

•Using show Commands to Verify the New Interface Status

•Using the ping Command to Verify Network Connectivity

•Using loopback Commands

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace service modules, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured SM. When you shut down an interface, it is designated administratively down in the show command displays.

Note To shut down additional interfaces, enter the interface serial command (followed by the interface address of the interface) for each of the interfaces on your SM. Use the no shutdown command to enable the interface.

Performing a Basic Interface Configuration

Following are instructions for a basic configuration, which include enabling an interface and configuring the SONET controller. You might also need to enter other configuration subcommands, 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 for SONET interfaces, refer to the appropriate software documentation.

In the following procedure, press the Enter key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Router# disable

Configuring the AU-3s and TUG-3s of a SM-1-STM1

You can configure each of the administrative unit groups (AUGs) and tributary unit groups (TUGs) of a SM-1-STM1 to carry a set of E1 links that are mapped into TU-12s (see Figure 4-1).

Figure 4-1

SM-1-STM1 Multiplexing Structure

Configuring an E1 Unframed Channel

To create an unframed or clear channel logical channel group on an E1 line, use the tug-2 tug-2# e1 e1# unframed command, as shown in the example below:
Router(config)# controller sonet 3/0
Router(config-controller)# au-4 1 tug-3 2
Router(config-controller-tug3)# tug-2 4 e1 1 unframed
Note The channel group is always 0 for unframed E1 lines.

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 and loopback commands to check connectivity. This section includes the following subsections:

•Using show Commands to Verify the New Interface Status

•Using the ping Command to Verify Network Connectivity

•Using loopback Commands

Using show Commands to Verify the New Interface Status

This section demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the module appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the "Related Documentation" section on page 5.

If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance.

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the "Related Documentation" section on page 5 for detailed command descriptions and examples.

The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#
If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.

Proceed to the, "Using loopback Commands" section, to finish checking network connectivity.

Using loopback Commands

With the loopback test, you can detect and isolate equipment malfunctions by testing the connection between the SM-1-STM1 interface and a remote device such as a multiplexer interface. The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device in the path of the loopback test.

The SM-1-STM1 supports two loopback modes at the sonet controller level: local and network.

Use the loopback {local | network} command to set the loopback mode, as shown below:
Router(config)# controller sonet 3/0
Router(config-controller)# loopback network
When the loopback local command is used, all data transmitted to the network is internally looped back to the receiver. In this loopback mode, the serial interfaces should go into up/up looped state.

When the loopback network command is used, all data received from the connected device is transmitted back unchanged. In this loopback mode, T1 serial interfaces are not working.

The SM-1-STM1 also supports loopback on E1 lines mapped to a TUG-3 or AU-3.

To specify a loopback on an E1 line that has been mapped to a TUG-3, use the tug-2 e1 loopback command in configuration controller tug3 mode.

To specify a loopback on an E1 line that has been mapped to an AU-3, use the tug-2 e1 loopback command in configuration controller au3 mode.

The complete tug-2 e1 loopback command syntax is:

tug-2 tug-2 number e1 e1-number loopback {local | network {line | payload}}

To disable the loopback, use the no form of this command:

[no] tug-2 tug-2 number e1 e1-number loopback {local | network {line | payload}}
