Console and Auxiliary Port Cable Connections

Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable

of asynchronous transmission. The DCE-mode console port is for connecting a console terminal and the DTE-mode auxiliary port is for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your router.

Step 1 Before connecting a terminal to the console port, configure the terminal to match the router console port as follows:

9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2).

Step 2 Use an auxiliary and console port cable. (An auxiliary port and console port cable and adapter kit is available from

Cisco Systems—Product Number ACS-2500ASYN=.) Use the console cable to connect the terminal to the console port. After you establish normal router operation, you can disconnect the terminal.

Note You must supply your own interface cable between the auxiliary port and the equipment you are connecting. For

console and auxiliary port pinouts, see the online Cisco 7401ASR Installation and Configuration Guide.

Gigabit Ethernet and Fast Ethernet Port Connections

The Cisco 7401ASR router has two native 10/100/1000-Mbps Ethernet interfaces. Each interface consists of two physical ports, an RJ-45 media port and a GBIC media port. The RJ-45 media ports provides 10/100-Mbps connectivity while the GBIC media ports provides 1000-Mbps connectivity.

Note The RJ-45 media is not capable of 1000 Mbps. This is only available via the Gigabit Ethernet GBIC media.

Note Any two of the four Ethernet ports may be used at the same time.

For more information, see the online Cisco 7401ASR Installation and Configuration Guide.

Intra-Building Lightning Protection

Shielded cables which are grounded at both ends are required to be used on the 10/100 Ethernet port in order to be in compliance with requirement R4-11 in GR-1089-Core for a Central Office environment. This is not a requi rement for customer premise installations.

Warning

To ide ntify the RJ-45 ca ble type, hold the two ends of the cable next to ea ch other so you can see the colored w ires inside the ends. The straight-through wire type has colored wires in the same sequence at both ends. In the crossover wire type, the first colored wire at the far left is the third colored wire at the other end. The second colored wire at the far left is the sixth colored wire at the other end.

Attach RJ-45 Ethernet cables to the appropriate connector.

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Note Both native Fast Ethernet/Ethernet ports and Gigabit Ethernet ports are reported as GE0/0 and GE0/1 in software. Y ou

must use the media-type command to select which media type you want to use before you configure th ese ports. See “Configure the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces” section on page 28.

GBIC Cabling and Connection Equipment

The Gigabit Interface Converter (GBIC) port is a 1000-Mbps optical interface in the form of an SC-type duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. Gigabit Interface Converter models WS-G5486 or GBIC-SX=, WS-G5484 or GBIC-LX/LH=, and WS-G5487 or GBIC-ZX-SM= are supported in the Cisco 7401ASR ro uter. For cabling distances, specifications, and other information, see the online Cisco 7401ASR Router Insta llation and Configuration Guide at http://www.cisco.com/univercd/cc/td/doc/product/core/7401/7401icg/index.htm.

Note All Gigabit Ethernet GBIC ports have SC-type connectors.

Warning

ecause invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid

7 Configure the Router

Perform a Basic Configuration Using the Setup Facility

If you do not plan to use AutoInstall, do not connect the router’s serial (WAN) cable to the channel service unit/data service unit (CSU/DSU). If the WAN cable is not connected, the router boots from Flash memory and goes auto matically into the setup facility.

You can run the setup facility any time you are at the enable prompt (#) by entering the setup command. If the serial (WAN) cable is connected to the CSU/DSU and the ro uter does not have a co nfiguration stored in NVRAM, the

router attempts to run AutoInstall at startup. The router may take several minutes to determine that AutoInstall is not set up to a remote TCP/IP host. Once the router determines that AutoInstall is not configured, it defaults to the setup facility.

Configure Global Parameters

When you first start the setup program, you must configure the global parameters. These parameters are used for controlling system-wide settings. Complete the following steps to enter the global parameters:

Step 1 Connect a console terminal to the console port, and then boot the router.

The system boots from Flash memory. The following information appea rs after about 30 seconds. When you see this information, you have successfully booted your router:

Step 9 Save your settings to NVRAM. See the “Save the Running Configuration to NVRAM” section on page 33. If you do

not save the configuration settings that you created in the router using configuration mode and the setup facility, your configuration will be lost the next time you reload the router.

Configure the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces

Changing the Media Type

Note The Cisco 7401ASR router reports both the Fast Ethernet/Ethernet and the Gigabit Ethernet ports as GE 0/0 and

GE 0/1. Before configuring either port type, you must first use the media-type interface command to select the media type, either Gigibit Ethernet (gbic) or Fast Ethernet/Ethernet (rj45).

Step 1 To be able to use a particular media port, use Cisco IOS to select the media type. This is done by using the media-type

interface command:

media-type { gbic | rj45 }

Example: interface GigabitEthernet 0/0 media-type rj45 end

Step 2 After changing the media type, configure the speed and duplex to appropriately match the new interface characteristics.

Changing the speed and duplex of a Cisco 7401ASR router Gigabit Ethernet interface is d one using the speed and duplex interface commands.

Note These commands are only applicable when using the RJ-45 me dia.

speed { 10 | 100 | 1000 | auto } duplex { full | half | auto }

The following speed/duplex settings are supported:

Media Type Speed Duplex

------------------------------------------------------RJ45 10, 100, auto full, half, auto GBIC ignored (1000) ignored (full) (By default on this interface)

-------------------------------------------------------

When using the GBIC media, there is also the additional negotiation auto command that is used to enable the IEEE

801.1z Gigabit Ethernet (1000 Mbps) autonegotiation protocol.

Step 3 To turn the negotiation auto feature off (it is on by default), issue the interface command no negotiation auto. This is

useful for connecting to other Gigabit Ethernet equipment that does not support 802.1z autonegotia tion.

Note The negotiation auto feature is not supported when using the media type rj-45 and will be ignored if

implementation is attempted.

If you change from the GBIC to the rj-45 media type, you must set speed and duplex after you have executed the media-type command to ensure the interface will operate in the correct mode.

The media-type GBIC mode will always default to 1000-Mbps, full-duplex operation as this is the only configuration that is supported in this mode. Any speed or duplex commands are ignored while using this media type, even if present in the config (for example, show running-config).

Debug

Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is either 0 or 1) and show controllers GigabitEthernet 0/X (where X is either 0 or 1).

The output of the show interface command is useful for determining the current operating mode of the interface (speed/duplex/media-type) and the current interface statistics.

The output of the show controller command displays more information specific to the Cisco 7401ASR router Gigabit Ethernet interface. For example, it shows the detected link status, speed, and duplex, and also determines the current status of autonegotiation and the link partners’ abilities (if it is an autonegotiation-capable interface).

The show controller command also displays the current operating state of the driver and the Ethernet controller hardware. The show controller command is a very powerful debugging aid, especially for Cisco engineers should you need help in debugging a problem. If you have any problems with your Gigabit Ethernet interfaces, you will need to provide this information to Cisco for analysis.

Reset the Interface

Should you have a problem with your interface and wish to try and reset it, use the command: clear interface GigabitEthernet 0/X (where X is either 0 or 1)

Clear Counters

Interface counters may be cleared (reset) by using the comman d: clear counters GigabitEthernet 0/X (where X is either 0 or 1) This will not reset the interface.

Configure Port Adapter Interfaces

Following are the steps for configuring interfaces to allow communication over a LAN or WAN. To configure the interface parameters, you need your interface network addresses and subnet mask information. Consult with your network administrator for this information.

Configure ATM Interfaces

In the following example, an ATM interface in slot 1 is configured for an ATM LAN using IP. Follow these steps to configure an ATM interface:

Step 1 Using your own addresses and mask at the setup prompts, respond to the prompts as follows:

Configuring interface parameters:

Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network number:

Configure IPX on this interface? [no]: yes IPX network number [2]:

Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and

then enter the cable range number. Enter the zone name and any other additional zones that a re associated with your local zone:

Configure AppleTalk on this interface? [no]: yes Extended AppleTalk network? [no]: yes AppleTalk starting cable range [0]:

Step 4 Save your settings to NVRAM. See the “Save the Running Configuration to NVRAM” section on page 33. If you do

not save the configuration settings that you created in the router using configuration mode and the setup facility, your configuration will be lost the next time you reload the router.

Note If additional ATM interfaces are available in your system, you are prompted for their configurations as well.

Configure Fast Ethernet Interfaces

In the following example, a Fast Ethernet interface in slot X is configured for a Fast Ethernet LAN using IP. Follow these steps to configure Fast Ethernet interfaces:

Step 1 Using your own addresses and mask at the setup prompts, respond to the prompts as follows:

Configuring interface parameters:

Configuring interface FastEthernet1/0: Is this interface in use? [yes]: Use the 100 Base-TX (RJ-45) connector? [yes]: Operate in full-duplex mode? [no]: Configure IP on this interface? [yes]: IP address for this interface: 1.1.1.20 Number of bits in subnet field [0]: Class C network is 1.1.1.0, 0 subnet bits; mask is /24

Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network number:

Configure IPX on this interface? [no]: yes PX network number [2]:

Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and

then enter the cable range number. Enter the zone name and any other additi onal zones that are associa ted with your local zone:

Configure AppleTalk on this interface? [no]: yes Extended AppleTalk network? [no]: yes AppleTalk starting cable range [0]:

Step 4 Save your settings to NVRAM. See the “Save the Running Configuration to NVRAM” section on page 33. If you do

not save the configuration settings that you created in the router using configuration mode and the setup facility, your configuration will be lost the next time you reload the router.

Note If additional Ethernet interfaces are available in your system, you are prompted for their configurations as well.

Configure Synchronous Serial Interfaces

Synchronous serial interfaces are configured to allow connection to WANs through a CSU/DSU. In the following example, a synchronous serial interface in slot X is configured for a W AN connection using IP. Follow these steps to configure synchronous serial interfaces:

Step 1 Using your own addresses and mask at the setup prompts, respond to the prompts as follows:

Configuring interface parameters:

Configuring interface serial 1/0: Is this interface in use? [yes]: Configure IP on this interface? [yes]: IP address for this interface: 1.1.1.30 Number of bits in subnet field [0]: Class A network is 1.1.1.0, 0 subnet bits; mask is /24

Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network number:

Configure IPX on this interface? [no]: yes IPX network number [2]:

Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and

then enter the cable range number. Enter the zone name and any other additi onal zones that are associa ted with your local zone:

Configure AppleTalk on this interface? [no]: yes Extended AppleTalk network? [no]: yes AppleTalk starting cable range [0]:

Step 4 Save your settings to NVRAM. See the “Save the Running Configuration to NVRAM” section on page 33. If you do

not save the configuration settings that you created in the router using configuration mode and the setup facility, your configuration will be lost the next time you reload the router.
