Installing and Configuring the MGX-XF-UI Management Back Card

This chapter describes how to install and configure the MGX-XF-UI management back card that is used in conjunction with and to configure the Cisco Route Processor Module (RPM-XF). This chapter includes the following sections:

•Overview and Features

•Installation Guidelines

•Software Configuration

•Troubleshooting the Installation

Overview and Features

The MGX-XF-UI management back card (Figure 4-1) provides remote management capabilities for the RPM-XF.

Figure 4-1 MGX-XF-UI Management Back Card

The management back card provides the following features:

•Multi-speed auxiliary port—The auxiliary port (AUX) is an asynchronous EIA/TIA-232 serial port used to connect an external terminal for local administrative access. The auxiliary port is capable of operating at a user specified baud rate (1200-115200 baud).

Note Connecting to the auxiliary port through a modem is not supported.

•Multi-speed console port—The console port (Console) is an asynchronous EIA/TIA-232 serial port used to connect an external terminal for local administrative access. The console port is capable of operating at a user specified baud rate (1200-115200 baud).

Note It is recommended that the console port speed always be set to 9600 baud.

•Two fast ethernet ports—The MGX-XF-UI contains two IEEE 802.3u-compliant fast ethernet ports (Ethernet 0 and Ethernet 1) used to connect the RPM-XF to a 10BaseT or 100BaseT network management LAN.

Fast Ethernet Overview

Fast Ethernet is commonly used for all carrier sense multiple access/collision detection (CSMA/CD), local-area networks (LANs) that generally conform to Ethernet specifications, including Fast Ethernet under IEEE 802.3u.

IEEE 802.3u is well suited to applications where a local communication medium must carry sporadic, occasionally heavy traffic at high peak data rates. Stations on a CSMA/CD LAN can access the network at any time. Before sending data, the station listens to the network to see if it is in use. If it is, the station waits until the network is not in use, then transmits; this is a half-duplex operation. A collision occurs when two stations listen for network traffic, hear none, and transmit very close to simultaneously. When this happens, both transmissions are damaged, and the stations must retransmit. The stations detect the collision and use backoff algorithms to determine when they should retransmit.

Both Ethernet and IEEE 802.3u are broadcast networks, which means that all stations see all transmissions. Each station must examine received frames to determine whether it is the intended destination and, if it is, pass the frame to a higher protocol layer for processing.

Each physical layer protocol has a name that summarizes its characteristics in the format speed/signaling method/segment length,

where

•speed is the LAN speed in megabits per second (Mbps),

•signaling method is either baseband or broadband, and

• segment length is typically the maximum length between stations in hundreds of meters.

Therefore, 100BaseT specifies a 100-Mbps, baseband LAN with maximum network segments.

IEEE 802.3u 100BaseT Fast Ethernet Specifications

Each Fast Ethernet port on the MGX-XF-UI back card has an RJ-45 connector to attach to Category 5 UTP for 100BaseTX. Figure 4-1 shows the Fast Ethernet MGX-RJ45-FE back card. Table 4-1 lists the cabling specifications for 100-Mbps Fast Ethernet transmission over UTP cables. Table 4-2 summarizes IEEE 802.3u 100BaseT physical characteristics.

Installation Guidelines

This section contains guidelines for the following procedures:

•New installation

•Replacement installation

The Cisco MGX-XF-UI back cards are cold swappable, which means you can remove and replace the back cards when all interfaces on the back cards are in the shutdown state.

Caution Handling of back cards requires proper observance of ESD practices and procedures. During installation or removal of back cards, the operator must be appropriately grounded and place all sensitive electronics in approved ESD containers or packaging.

New Installation Guidelines

For information on installing the back cards, see the "Installing and Removing Back Cards in the MGX 8850 Midplane" section.

After installing the MGX-XF-UI for the first time, you must configure it by entering the configure command. For information about configuring the management back card, see the "Software Configuration" section below.

Replacement Installation Guidelines

For information on removing and installing the back card hardware, refer to the "Installing and Removing Back Cards in the MGX 8850 Midplane" section.

If a management back card is replaced, the system automatically downloads the necessary information from the RPM-XF front card. There is no need to configure the new back card unless the front card has been reloaded or switched over subsequent to the removal of the back card. After the information is downloaded, the system recognizes only those interfaces that match the previous management back card configuration (those configured as Up).

Software Configuration

After the management back card is successfully installed you can configure the interfaces on the card.

Note You do not need to configure the management back card if this is a replacement installation. The system automatically downloads the necessary configuration information from the RPM-XF front card.

Console and Auxiliary Port Configuration Commands

The following sections present some of the commands that you can use to customize your console and auxiliary port configuration.

This section covers the following topics:

•Setting the Port Speed for the Console and Auxiliary Ports

•Setting the Number of Data Bits for the Console and Auxiliary Ports

•Setting the Number of Stop Bits for the Console and Auxiliary Ports

•Setting the Parity for the Console and Auxiliary Ports

Setting the Port Speed for the Console and Auxiliary Ports

You can use the speed command to set the speed for the port.

speed baud rate

The default is 9600 baud.

Note Setting the console port speed also adjusts the ROM Monitor configuration register for the console port speed.

Because the ROM Monitor only supports a limited number of console port speeds, it is recommended that the console port speed be set to one of the following baud rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.

Because the ROM Monitor only supports the auxiliary port at 9600 baud, it is recommended that the auxiliary port speed be set to 9600 baud.

In this example, the console port is setup to use 9600 baud.

Router(config)# line console 0

Router(config-line)# speed 9600

Setting the Number of Data Bits for the Console and Auxiliary Ports

You can use the databits command to set the number of data bits for the port.

databits [5 | 6 | 7 | 8]

The default is 8 data bits.

Note Because the ROM monitor only supports 8 data bits, it is recommended that the number of data bits be set to 8.

In this example, the console port is setup to use 8 data bits.

Router(config)# line console 0

Router(config-line)# databits 8

Setting the Number of Stop Bits for the Console and Auxiliary Ports

You can use the stopbits command to set the number of stop bits for the port.

stopbits [1 | 1.5 | 2]

The default is 1 stop bit.

Note Because the ROM monitor only supports 1 stop bit, it is recommended that the number of stop bits be set to 1.

In this example, the console port is setup to use 1 stop bit.

Router(config)# line console 0

Router(config-line)# stopbits 1

Setting the Parity for the Console and Auxiliary Ports

You can use the parity command to set the parity for the port.

parity [even | mark | none | odd | space]

The default is no parity.

Note Because the ROM monitor does not support parity, it is recommended that parity be set to none.

In this example, the console port is setup to use no parity.

Router(config)# line console 0

Router(config-line)# parity none

Fast Ethernet Port Syntax

To specify an interface number in a configuration command, use the syntax in Table 4-6 to identify fast ethernet interfaces on the management back card.

The following example shows the syntax for configuring the first fast ethernet port on the management back card.

Router(config)# interface FastEthernet 2/0

Configure the Fast Ethernet Port

After you verify that the management back card is installed correctly, use the following procedure to configure the fast ethernet ports. Be prepared with the information you will need, such as the interface IP address.

The following is for creating a basic configuration—Enabling an interface.

Step 1 At the global configuration prompt, specify the fast ethernet port by entering interface FastEthernet bay/port. For example,

Router(config)# interface FastEthernet 2/0

Step 2 Assign an IP address and a subnet mask to the interface with the ip address configuration subcommand. For example,

Router(config-if)# ip address 192.168.255.255 255.255.255.0

Step 3 Configure the fast ethernet port speed. For example,

Router(config-if)# speed auto

Step 4 Configure the fast ethernet port duplex. For example,

Router(config-if)# duplex auto

Step 5 Add any other configuration subcommands required.

Step 6 Enter the no shutdown command to enable the interface. For example,

Router(config-if)# no shutdown

Step 7 When you have included all of the configuration subcommands to complete the configuration, press Cntl-Z to exit configuration mode.

Step 8 Write the new configuration to memory.

Router# copy running-config startup-config

The system displays an OK message when the configuration is saved.

After you complete the configuration, check it using show interface FastEthernet bay/port.

Fast Ethernet Port Configuration Commands

The following sections present some of the commands that you can use to customize your fast ethernet port configuration.

This section covers the following topics:

•Setting the Fast Ethernet Port Speed

•Setting the Fast Ethernet Port Duplex

Setting the Fast Ethernet Port Speed

You can use the speed command to set the speed for the port.

speed [auto | 10 | 100]

The default is auto negotiation.

In this example, fast ethernet port 0 is setup to use auto negotiation.

Router(config)# interface FastEthernet 2/0

Router(config-line)# speed auto

Setting the Fast Ethernet Port Duplex

You can use the speed command to set the duplex mode for the port.

duplex [auto | half| full]

The default is auto negotiation.

In this example, fast ethernet port 0 is setup to use auto negotiation.

Router(config)# interface FastEthernet 2/0

Router(config-line)# duplex auto

Fast Ethernet Port Example Configuration

The following is an example of configuration file commands for the console and auxiliary ports on the management back card.

end

Verifying Ethernet Connectivity

The ping command lets you verify that an interface port is functioning and check the path between a specific port and connected network devices. This section provides brief descriptions of the ping command. After you verify that the system has booted successfully and is operational, you can use this command to verify the status of interface ports. The remote device can be a server, a router, or a PC.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified time-out 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 that the connection failed.

The following is an example of a successful ping command to a remote server with the address 1.1.1.10.

Router#ping 1.1.1.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 1.1.1.10, timeout is 2 seconds:

.!!!!

Success rate is 80 percent (4/5), round-trip min/avg/max = 1/1/1 ms

Router#

If the connection fails, verify that you entered the correct IP address for the remote device and that the remote device is active (powered on). Then repeat the ping command.

Using show Commands to Check System Status

Each interface maintains information about its configuration, traffic, errors and so on. You can access this information by entering the show commands. Following are descriptions and examples of show commands that display interface information and status.

Enter the show interface FastEthernet bay/port command to show general information about the interface.
