Configuring the Cisco MGX 8850 RPM

This chapter describes how to complete a basic configuration of the Cisco MGX 8850 Route Processor Module (RPM), provides procedures for configuring ATM, Ethernet, Fast Ethernet and FDDI port adapter interfaces, permanent virtual circuits (PVCs) and the connections between the RPM and the PXM and either service modules or other RPMs. This chapter contains the following sections:

•Accessing the RPM Command-Line Interface

•Booting the RPM

•Configuring the RPM

•Configuring Port Adapter Interfaces

•Checking the Configuration

•Specifying the Boot Method

•Cisco IOS Software Basics

This chapter provides information to get the RPM up and running. Detailed software configuration information is available in the Cisco IOS configuration and command reference publications, which are available on the Cisco Documentation CD-ROM.

Accessing the RPM Command-Line Interface

To configure the RPM, you must access the command-line interface (CLI) of the RPM.

The RPM CLI can be accessed using any of the following three methods:

•Console port on the front of the RPM

The RPM has an RJ-45 connector on the front of the card module. If you configure the RPM on site, connect a console terminal (an ASCII terminal or a PC running terminal emulation software) directly to the console port on your RPM using an RS-232 to RJ-45 cable for CLI access (see "Installing the Cisco MGX 8850 RPM"). The console port is the only way to access the RPM CLI when the card module is first installed into an MGX 8850 chassis.

•cc from another MGX 8850 card

After initial configuration, you can also configure the RPM through the PXM. You can access the RPM CLI by using the cc (change card) command from any of the other cards in the MGX 8850 switch. The ATM switch interface on the RPM must be enabled before you can use the cc command.

•Telnet from a workstation, PC or another router

After initial configuration, you can also configure the RPM remotely via telnet. After the RPM is installed and has PVCs to other RPMS or routers in the network, you can telnet to the RPM CLI remotely from these other devices. To connect a modem to the auxiliary port on the RPM see "Installing the Cisco MGX 8850 RPM".

Booting the RPM

Note To power cycle the RPM, turn off the MGX 8850 system, wait five seconds, then turn it on again. Note that turning off the MGX 8850 chassis will affect other installed cards. Alternatively, remove and reinstall the RPM. You can also cycle the RPM by typing the command resetcd [card_number] from the PXM. Note that card_number should be the slot number of the RPM to reboot. Omitting the card number resets the entire system. Also you may power cycle the RPM via the Command Line Interface. The Cisco IOS CLI command is reload.

Each time you turn on power to the RPM (insert the RPM into the MGX 8850), it goes through the following boot sequence:

1. The RPM goes through power-on self-test diagnostics to verify basic operation of the CPU, memory, and interfaces.

2. The system bootstrap software (boot image) executes and searches for a valid Cisco IOS image (the RPM operating system software).

The source of the Cisco IOS image is determined by the configuration register setting. The factory-default setting for the configuration register is 0x2102 which means the RPM will first look for the IOS image in bootflash.

However, since the RPM-A normally has bootflash only large enough to hold the bootstrap image and not the entire IOS operating system image, boot system configuration commands must be used to override the default boot system and specify a Cisco IOS image file on a TFTP server or the PXM C: drive.

For the RPM-B the bootflash contains the entire IOS operating system image.

Note If the customer purchases an upgrade to the RPM-A from 4MB to 8MB or to 20MB flash, then bootflash can hold a full image (two in the 20MB case) and the IOS image can operate from bootflash. The RPM-B already contains 16MB flash.

3. If after five attempts the boot system configuration commands each fail to find a valid IOS image on a TFTP server or on the PXM C: drive, and no valid IOS image is found in bootflash, the RPM reverts to rommon mode (which is used to install or upgrade a Cisco IOS image).

4. If a valid Cisco IOS image is found, then the RPM searches for a valid configuration file.

5. If a valid configuration file is not found in NVRAM, the RPM runs the System Configuration Dialog so you can configure it manually. For normal RPM operation, there must be a valid Cisco IOS image on a TFTP server, the PXM C: drive, or in bootflash, and a configuration file in NVRAM.

The first time you boot the RPM, you need to configure the RPM interfaces and then save the configuration to a file in NVRAM. Proceed to the next section, "Booting the RPM From the PXM" and the section, "Configuring the RPM," for instructions.

Booting the RPM From the PXM

The IOS image should be stored on the PXM hard drive. To confirm this, make sure you are in the /RPM directory and use the ls command to list the contents of the directory. You should see a file named "xxx" which is the IOS image.

The following are PXM commands illustrating this command sequence: 

NODENAME.1.7.PXM.a > cd C:RPM


NODENAME.1.7.PXM.a > ls

.

..

rpm-is-mz.120-4.0.1.T


In the file system :

    total space : 3176712 K bytes

    free  space : 3067819 K bytes


NODENAME.1.7.PXM.a >

If this image is not there you will need to use the TFTP file-transfer application to load the image to the PXM hard drive.

The following is an TFTP example: 

marka-u5:4> ls -l rpm-is-mz.120-4.0.1.T

-rw-r--r--   1 marka    eng       4560820 Apr  2 12:16 rpm-is-mz.120-4.0.1.T

marka-u5:5> tftp 172.29.37.154

tftp> bin

tftp> put rpm-is-mz.120-4.0.1.T RPM/rpm-is-mz.120-4.0.1.T

Sent 4560820 bytes in 41.2 seconds

tftp> q

marka-u5:6>

To load the IOS image from the PXM hard drive, the RPM must be configured to do so.

Before the RPM can load the IOS image from the PXM, the RPM's ATM switch interface must first be enabled. Use the Console port on the RPM to boot the RPM from Flash so that you can configure its ATM switch interface.

In configuration mode type interface switch slot/1 to access the interface configuration. Type no shutdown to activate the interface.

The following illustrated how to enable the RPM's ATM interface: 

RPM(boot)#config term

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

RPM(boot)(config)#interface Switch9/1

RPM(boot)(config-if)#no shutdown

RPM(boot)(config-if)#

00:06:55:%LINK-3-UPDOWN:Interface Switch9/1, changed state to up

00:06:56:%LINEPROTO-5-UPDOWN:Line protocol on Interface Switch9/1,

changed sta

te to up

RPM(boot)(config-if)#^Z

RPM(boot)#

00:07:01:%SYS-5-CONFIG_I:Configured from console by console

RPM(boot)#

Now, use boot system configuration commands to override the default boot setting. Type the following configuration command to configure the RPM to boot from the PXM: 

MGX8850-RPM (config)# boot system c:filename

Then reload the RPM and boot the Cisco IOS from the PXM disk.

Note Put the RPM's Cisco IOS image in the RPM directory of the PXM hard disk with the filename specified in the RPM boot command.

To verify the accessibility of the PXM C:drive from the RPM, issue the following privileged-level EXEC command: 

MGX8850-RPM# dir c:

Directory of c:/ 


     -rw-     5584092   Oct 19 1999 15:39:54  rpm-js-mz.120-4.T 

     -rw-     1680448   Oct 19 1999 15:39:54  rpm-boot-mz.120-2.T

Configuring Port Adapter Interfaces

Once port adapter cable connections have been made (refer to "Cabling Cisco MGX 8850 RPM Port Adapters" for connector descriptions and cable attachment instructions) and basic configuration on the RPM is completed, ATM, Ethernet, Fast Ethernet and FDDI port adapter interfaces on the RPM must be configured. This is then followed by configuration of permanent virtual circuits (PVCs) and the connections between the RPM and the PXM and either service modules or other RPMs.

Preparing to Configure Port Adapter Interfaces

If you want to configure interfaces in a new RPM or if you want to change the configuration of an existing interface, be prepared with the information you will need, such as the following:

•Protocols you plan to route on each new interface.

•Internet protocol (IP) addresses if you plan to configure the interfaces for IP routing.

•Whether the new interfaces will use bridging.

•Whether the new interfaces will use LAN.

The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.

Identifying Chassis Slot, Port Adapter Slot, and Interface Port Numbers

The following section describes how to identify chassis slot, port adapter slot, and interface port numbers on the RPM for all port adapter interface types.

RPM Port Adapter Interface Ports

Physical port addresses specify the actual physical location of each interface port, regardless of the type, on the RPM. In the RPM, this address is composed of a three-part number in the format chassis-slot/port adapter slot number/interface port number, as follows:

•The first number identifies the chassis slot in which the RPM is installed. This number is assigned to the RPM during the initial configuration.

•The second number identifies the port adapter slot in which the port adapter is installed, either upper (1) or lower (2) port adapter.

•The third number identifies the interface port(s) on the port adapter.

You can also identify port adapter interface ports by physically checking the slot/interface port location on the front of the RPM or by using show commands to display information about a specific interface or all interfaces in the RPM.

Configuring the ATM Interface

Note All port adapters on the RPM are removable except for the ATM port adapter. The ATM interface is always port #1.

This section provides the procedure for a basic interface configuration.

Press Return 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: 

RPM-3# disable


RPM-3>

Use the following procedure to perform a basic configuration:

Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands, as follows: 

RPM-3# configure terminal

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

RPM-3(config)#

Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by switch to specify the internal ATM interface, then slot/port (for slot of the MGX 8850 chassis where the RPM is located, and for port number on the port adapter). The example that follows show the atm interface as 1 in the RPM in slot 5 of the MGX 8850: 

RPM-3(config)# interface switch 5/1

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example: 

RPM-3(config-if)# ip address 192.168.1.10 255.255.255.0

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows: 

RPM-3(config-if)# no shutdown

Step 6 When you have completed the configuration, press Ctrl-Z to exit configuration mode.

Step 7 Write the new configuration to nonvolatile memory as follows: 

RPM-3# copy running-config startup-config

[OK]

RPM-3#

Note Since the switch interface is not removable, it should always be set to no shutdown.

Note The ATM interface can be divided subinterfaces as needed. To see how to configure subinterfaces on the ATM switch interface, refer to the section, "Configuring Permanent Virtual Circuits" later in this chapter.

Configuring 4E Interfaces

The Ethernet interfaces are configured to allow a connection to a LAN. To configure the interface parameters, you need to know your Ethernet interface network addresses.

Take the following basic configuration steps to configure an Ethernet interface to allow communication over a LAN:

Press Return 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: 

RPM-3# disable

RPM-3>

Following is an example of a basic configuration procedure:

Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands, as follows: 

RPM-3# configure terminal

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

RPM-3(config)#

Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by ethernet to specify port adapter type, then slot/card/port (for slot of the MGX 8850 where the RPM resides, upper (1) or lower (2) port adapter, and for port number on the port adapter).

Note The 4E interfaces here are numbered 1, 2, 3, 4 and not 0, 1, 2, 3 as in other IOS platforms.

Step 3 The example that follows is the 2 interface of the lower ethernet port adapter in the RPM in slot 5 of the MGX 8850: 

RPM-3(config)# interface e 5/2/2

Step 4 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in this example: 

RPM-3(config-int)# ip address 1.1.1.10 255.255.255.0

Step 5 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 6 Change the shutdown state to up and enable the interface as follows: 

RPM-3(config-int)# no shutdown

Step 7 Configure additional interfaces as required.

Step 8 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.

Step 9 Write the new configuration to nonvolatile memory as follows: 

RPM-3# copy running-config startup-config

[OK]

RPM-3#

To check the interface configuration using show commands, proceed to the section "Checking the Configuration."

Configuring FE Interfaces

The following steps describe a basic configuration. Press Return 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: 

RPM-3# disable


RPM-3>

Following is an example of a basic configuration procedure:

Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands, as follows: 

RPM-3# configure terminal

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

RPM-3(config)#

Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by fastethernet to specify port adapter type, then slot/card/port (for slot of the MGX 8850 where the RPM resides, upper (1) or lower (2) port adapter, and for port number on the port adapter). The example that follows is the 1 interface of the upper fastethernet port adapter in the RPM in slot 5 of the MGX 8850: 

RPM-3(config)# interface fastethernet 5/1/1

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example: 

RPM-3(config-if)# ip address 1.1.1.10 255.255.255.0

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows: 

RPM-3(config-if)# no shutdown

Step 6 Configure additional interfaces as required.

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

Step 8 Write the new configuration to nonvolatile memory as follows: 

RPM-3# copy running-config startup-config

[OK]

RPM-3#

This completes the procedure for creating a basic configuration.

Half-duplex operation is the default transmission mode for the FE port adapters. Use the full-duplex command to configure full-duplex operation for the FE port adapters as follows: 

RPM-3# configure terminal

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

RPM-3(config)#

RPM-3(config)# interface fastethernet 5/2/1

RPM-3(config-if)# full-duplex

Ctrl-z

Use the show interfaces fastethernet command to verify that the 2/1 Fast Ethernet interface is now configured for full-duplex operation as follows: 

RPM-3# sh int fastethernet 5/2/1

FastEthernet 5/2/1 is administratively up, line protocol is up

 (display text omitted)

 Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX

Use the no full-duplex command to return the interface to half-duplex operation as follows: 

RPM-3# config t

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

RPM-3(config)# int fastethernet 5/2/1

RPM-3(config-if)# no full-duplex

Ctrl-z

RPM-3#

Use the show interfaces fastethernet command to verify that the 2/1 Fast Ethernet interface is now configured for half-duplex operation as follows: 

RPM-3# sh int fastethernet 5/2/1

FastEthernet5/2/1 is administratively up, line protocol is up

 (display text omitted)

 Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX

 (display text omitted)

The RJ-45 receptacle is the default media type for FE-TX port adapter and the SC receptacle (for fiber-optic connections) is the default media type for FE-FX port adapter. Use the media-type mii command to configure the MII receptacle as the media type for the FE port adapters as follows: 

RPM-3# config t

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

RPM-3(config)# int fa 5/2/1

RPM-3(config-if)# media-type mii

Ctrl-z

RPM-3# sh int fa 5/2/1

FastEthernet2/1 is administratively up, line protocol is up

 (display text omitted)

 Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII

 (display text omitted)

Use the media-type 100 command to return the media type for the FE port adapters to the RJ-45 receptacle or SC receptacle.

To check the interface configuration using show commands, refer to the section "Configuring 4E Interfaces" on page 76.

Configuring FDDI Interfaces

This section provides the procedures for performing a basic configuration of the interfaces on full-duplex FDDI port adapters installed in a RPM.

Press the Return 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: 

RPM-3# disable


RPM-3>

Use the following procedure to perform a basic configuration:

Step 1 At the privileged-level prompt, enter configuration mode. Specify that the console terminal will be the source of the configuration subcommands, as follows: 

RPM-3# configure terminal

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

RPM-3(config)#

Step 2 At the prompt: enter the subcommand interface to specify the interface to be configured, followed by fddi to specify port adapter type, then slot/card/port (for slot of the MGX 8850 where the RPM resides, upper (1) or lower (2) port adapter, and for port number on the port adapter). The example that follows is the 1 interface of the upper fddi port adapter in the RPM in slot 5 of the MGX 8850: 

RPM-3(config)# interface fddi 5/1/1

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example: 

RPM-3(config-if)# ip address 1.1.1.10 255.255.255.0

Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows: 

RPM-3(config-if)# no shutdown

Step 6 Configure additional interfaces as required.

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

Step 8 Write the new configuration to nonvolatile memory as follows: 

RPM-3# copy running-config startup-config

[OK]

RPM-3#


To check the interface configuration using show commands, refer to the section "Configuring FDDI Interfaces" on page 79.

Note If you require full-duplex operation, verify that you are using PA-F/FD-SM or PA-F/FD-MM port adapters.

Configuring Full-Duplex Operation

Full-duplex operation requires FDDI port adapters PA-F/FD-SM or PA-F/FD-MM.

Full-duplex operation is not the default configuration and must be turned on using the full-duplex command. To turn off full-duplex operation (and enable half-duplex operation) and reset the interface, use the no full-duplex (or half-duplex) command.

Following is an example of configuring an FDDI interface for full-duplex operation using the full-duplex command: 

RPM-3# conf t

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

RPM-3(config)# int fddi 5/2/1

RPM-3(config-if)# full-duplex

Ctrl-z

RPM-3#

Note If the port adapter does not support full-duplex operation, the following error message will appear: "%FDDI5/2/1 interface does not support full-duplex." If the port adapter does support full-duplex operation, the interface will reset as it changes to full-duplex operation.

The output of the show interfaces fddi slot/card/port command displays the state of the FDDI port adapter interface and the state of full-duplex operation. Following is a partial sample output of this command from an FDDI interface with full-duplex operation enabled: 

RPM-3# show int fddi 5/2/1

Fddi5/4/0 is up, line protocol is up 

 Hardware is MIF68840_MM, address is 0060.7054.8808 (bia 0060.7054.8808)

  FDX supported, FDX enabled, FDX state is *

where *, in the last line, could be idle, request, confirm, or operation, depending on the state the FDDI interface was in when the show interfaces command is entered.

When full-duplex operation is turned off using the no full-duplex (or half-duplex) command, the last line of the preceding display includes the following information: FDX supported, FDX disabled. If the port adapter does not support full-duplex, the message FDX NOT supported is displayed.

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and the ping command to check connectivity.

Using Show Commands to Verify the New Interface Status

The following steps use show commands to verify that the new interfaces are configured and operating correctly.

Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new interfaces.

Step 2 Display all the current port adapters and their interfaces with the show controllers command.

Step 3 Specify one of the new interfaces with the show interfaces port adapter type slot/card/interface command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.

Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or specific interfaces.

Step 5 Display the running configuration file with the show running-config command.

Step 6 Display the configuration stored in NVRAM using the show startup-config command. Verify that the configuration is accurate for the system and each interface.

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance. For detailed software configuration information, refer to the Cisco IOS configuration and command reference publications. These publications are available on the Documentation CD-ROM that came with your RPM, or you can order printed copies.

Using Show Commands to Display Interface Information

To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/card/port] for the MGX 8850 RPM.

Note For complete command descriptions and examples for all of the supported platforms, refer to the publications listed in the Preface About This Guidein the section, "Objectives."

RPM Show Interfaces Command

Following is an example of how the show interfaces [type slot/card/port] command displays status information (including the chassis physical slot, card number and port address) for the interfaces you specify. In these examples, the four Ethernet 10BASE-T interfaces (1-4) are in the lower port adapter in the RPM in slot 4 of the MGX 8850 (interfaces are administratively shut down until you enable them).

With the show interfaces type slot/card/port command, use arguments such as the interface type (ethernet, and so forth), slot, card and the port number (slot/card/port) to display information about a specific Ethernet 10BASE-T interface only.


The show version (or show hardware) command displays the configuration of the system hardware (the number of each port adapter type installed), the software version, the names and sources of configuration files, and the boot images. Following is an example of the show version command: 

RPM-3# show version

Proceed to the next section "Using the ping Command" to verify that each interface port is functioning properly.

Using the ping Command

The packet internet groper (ping) command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. 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 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.

Following is an example of a successful ping command to a remote server with the address 1.1.1.10: 

RPM-3# ping 1.1.1.10 <Return>

Type escape sequence to abort.

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

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms

RPM-3#

If the connection fails, verify that you have the correct IP address for the server and that the server is active (powered on). Repeat the ping command.

Configuring Virtual Circuits on the RPM

A VC is a point-to-point connection between two or more devices. This section describes how to configure a PVC originating on the RPM ATM interface and terminating on a service module within a single MGX 8850 or on another RPM.

A VC is established for each ATM end node with which the RPM communicates. The characteristics of the VC are established when the VC is created and include the following:

•Quality of service (QOS)

•ATM Adaptation Layer 5 mode (AAL5)

•Encapsulation type (LLC/SNAP, MUX, and QSAAL)

Each RPM VC supports the following router functions:

•Mulitprotocol

–IP: static route, IGRP, RIP, OSPF, EIGRP

–IPX: static route, RIP, EIGRP

–XNS: static route, RIP, UB

–AppleTalk: RTMP, EIGRP

–CLNS: static route, ISO-IGRP, ISIS

–Vines: static route, RTP

–DECnet: PhaseIV, Phase IV Prime

•Fast switching of IP packets

•Pseudobroadcast support for multicast packets

Resource Partitioning

Like the other card modules in the MGX 8850 switch, resource partitions must be defined on the RPM. The rpmrscprtn command defines the bandwidth and addressing resources assigned to each controller (PAR, Tag or PNNI).

The rpmrscprtn command is used to modify the resource partitioning on the RPM. It is necessary to use the rpmrscprtn command before you add any PVCs or connections to the RPM because by default all partitions are disabled.

Type in the following command to set up resource partitioning: 

RPM-3(config)# rpmrscprtn PAR 100 100 1 255 0 3840 4047

Partition type [par|tag|pnni] Percent ingress [<0-100>] Percent egress [<0-100>] Minimum 
VPI [<0-255>] Maximum VPI [<0-255> Minimum VCI [<0-3840>] Maximum VCI [<0-3840>] Number of 
LCNs [<0-4047>]

Table 5-1 describes rpmrscprtn command parameters.

Table 5-1 rpmrscprtn Parameter Description

Parameter
Description

par | tag | pnni

The controller type that you want to define.

ingress-percent

The percentage of the ingress bandwidth on the ATM switch interface that can be allocated by the controller type. The aggregate of the ingress bandwidth across all three controllers can exceed 100 percent.

egress-percent

The percentage of the egress bandwidth on the ATM switch interface that can be allocated by the controller type. The aggregate of the egress bandwidth across all three controllers can exceed 100 percent.

min-vpi

The minimum VPI value that can be assigned on PVCs on this controller. The VPI range on the three controllers can overlap.

max-vpi

The maximum VPI value that can be assigned on PVCs on this controller. The VPI range on the three controllers can overlap.

min-vci

The minimum VCI value that can be assigned on PVCs on this controller. Unlike the VPI range, the VCI range cannot overlap the VCI range of another controller.

max-vci

The maximum VCI value that can be assigned on PVCs on this controller. Unlike the VPI range, the VCI range cannot overlap the VCI range of another controller.

Icns

The total number of logical connections that can use this controller.


Configuring Permanent Virtual Circuits

All permanent virtual circuits (PVCs) configured into the RPM remain active until the circuit is removed from the configuration. The PVCs also require a permanent connection to the ATM switch. All virtual circuit characteristics apply to PVCs. When a PVC is configured, all the configuration options are passed on to the ATM port adapter. These PVCs are writable into the nonvolatile RAM (NVRAM) as part of the RPM configuration and are used when the RPM image is reloaded.

Each PVC on the RPM is associated with a subinterface. Some subinterfaces support multiple PVCs (multipoint) that do the equivalent of broadcasting. Others only support one PVC (point-to-point). If a point-to-multipoint PVC exists, then that PVC can be used as the sole broadcast PVC for all multicast requests.

Each subinterface is identified as slot/interface.subinterface. The slot is the card slot number of the RPM, the interface is always 1, and the subinterface is a number that identifies the subinterface PVCs on the RPM.

A subinterface is created while in the configuration mode by typing the interface switch command. The IP address is set using the ip address command.

To configure a PVC, you must perform the following tasks:

Step 1 Create a point-to-point or multipoint subinterface.

Step 2 Assign an IP address to the subinterface.

Step 3 Create an ATM PVC.

Step 4 Define a map list (for multipoint only).

Step 5 Add a connection between the RPM and the PXM.

Step 6 Add the remaining connection segments as needed.

Refer to the document, MGX 8850 Wide Area Switch Installation and Configuration, for more information on creating PVCs on the RPM and the rest of the Cisco 7000 family of routers. Also refer the section, "Configuring Connections between the RPM and Other Devices," in this chapter.

Creating a PVC

When you create a PVC, you create a virtual circuit descriptor (VCD) and attach it to the virtual path identifier (VPI) and virtual channel identifier (VCI). A VCD is an ATM port adapter-specific mechanism that identifies to the ATM port adapter which VPI/VCI to use for a particular packet. The ATM port adapter requires this feature to manage packets for transmission. The number chosen for the VCD is independent of the VPI/VCI used. When you create a PVC, you also specify the AAL and encapsulation. A rate queue is used that matches the default peak and average rate, which are equal, and are specified in kilobits per second. To create a PVC on the ATM port adapter interface, use the atm pvc command. To remove a PVC, use the no form of this command. 

atm pvc vcd vpi vci aal-encap

no atm pvc vcd


RPM:

RPM-3(config)# interface switch chassis-slot/1.subinterface interface-type

Where the interface-type is either point-to-point, multipoint or tag. 

RPM-3(config-if)# atm pvc 2048 255 128 aal5snap

Note Since the atm port adapter is internal to the RPM and the interface is logical not physical, you can not remove it. It is always referred to as slot/1.

vcd—A unique index value describing this VC in the range of 1 to MAXVC (defined when setting up resource partitioning). Do not use VCD 1, as this is hardcoded.

vpi—The ATM network VPI to use for this VC in the range of 0 through 255. A VPI of 0 indicates that this PVC is a VCC. A non-0 value indicates that the PVC is a VPC.

vci—The ATM network VCI to use for this VC in the range of 0 through 3,824.

aal-encap—The encapsulation type to use on this VC from the following:

aal5mux—Specifies the MUX-type for this VC. A protocol type must be specified.
aal5snap—LLC/SNAP precedes the protocol datagram.
aal5nlpid—NLPID precedes the protocol datagram.
qsaal—A signaling type VC.
aal5ciscoppp—Used for PPP applications.

The atm pvc command creates PVC n and attaches the PVC to VPI and VCI. The AAL used is specified by aal and encapsulation by encap.

The default for peak rate and average rate is that peak = average, and the PVC is automatically connected to the highest bandwidth rate queue available. For detailed software configuration information, refer to the Cisco IOS configuration and command reference publications. These publications are available on the Documentation CD-ROM that came with your RPM, or you can order printed copies.

Mapping a Protocol Address to a PVC

Cisco IOS software supports a mapping scheme that identifies the ATM address of remote hosts/RPMs. This address can be specified either as a VCD for a PVC or a network service access point (NSAP) address for SVC operation.

Enter mapping commands as groups; multiple map entries can exist in one map list. First create a map list, then associate the list with an interface.

Enter the map-list name command; then enter the protocol, protocol address, and other variables, as follows: 

map-list name  
protocol-type protocol-address [atm-vc vcd] | atm-nsap nsap-address] [broadcast]

The broadcast keyword specifies that this map entry receives the corresponding protocol broadcast requests to the interface (for example, any network routing protocol updates). If you do not specify broadcast, the ATM software is prevented from sending routing protocol updates to the remote hosts.

After you create the map list, specify the ATM interface to which it applies with the interface command, as follows:


RPM usage: 

RPM-3# interface switch 5/1

Associate the map list to an interface with the following command: 

map-group name

You can create multiple map lists, but only one map list can be associated with an interface. Different map lists can be associated with different interfaces. The following is an example of the commands to map a list to an interface on a RPM: 

RPM-3# interface switch 5/1

ip address 1.1.1.2 255.255.255.0

 map-group atm1

 atm pvc 2 0 1 aal5snap

!

no ip classless

!

map-list atm1

 ip 1.1.1.1 atm-vc 2 broadcast

Note The RPM can not use VCD=1, since it already uses VCD=1 for the IP connection to the PXM.

Configuring Connections between the RPM and Other Devices

After configuring port adapters on the RPM, the next step is to configure connections between the RPM and other devices (service modules, other RPMs) via the PXM.

The PXM (the main processor on the MGX 8850) coordinates all communication between the RPM and service modules and other RPMs. See Figure 5-1 for a view of how service modules sit in the MGX 8850 and their physical relationship to the PXM and RPM.

Figure 5-1 Service Modules in the MGX 8850

A complete connection between the RPM and any of these devices includes two parts:

•The half between the RPM and the PXM.

•The half between the PXM and the service module or a different RPM.

Setting Up the RPM Connection to the PXM

Initially, you set up the connection between the RPM and the PXM.

For the RPM in slot 5 connecting to slot 2 perform the following steps:

Step 1 Set up physical interface: 

RPM-3# conf t

RPM-3(config)# int sw5/1 

RPM-3(config)# no shut

Step 2 Set up logical interface: 

RPM-3(config)# int sw 5/1.1 point-to-point 

ip address 1.0.0.1 255.0.0.0

Step 3 Set up pvc: 

RPM-3(config-if)# atm pvc 2 0 1 aal5snap

Step 4 To get back to the global level, type exit: 

RPM-3(config-if)# exit

RPM-3(config)#

Step 5 Then, type in the following command to set up resource partitioning: 

RPM-3(config)# rpmrscprtn PAR 100 100 1 255 0 3840 4047

Partition type [par|tag|pnni] Percent ingress [<0-100>] Percent egress [<0-100>] Minimum 
VPI [<0-255>] Maximum VPI [<0-255> Minimum VCI [<0-3840>] Maximum VCI [<0-3840>] Number of 
LCNs [<0-4047>]

Step 6 Add a connection to the pvc, either vcc (virtual circuit connection) or vpc (virtual path connection): 

RPM-3(config)# addcon vcc Switch slot/1[.sub-interface] vci [rname rname] rslot rslot 
r_int r_vpi r_vci [master {local | remote}] 


or


RPM-3(config)# addcon vpc Switch slot/1[.sub-interface] vpi [rname rname] rslot rslot 
r_int r_vpi [master {local | remote}]

slot — RPM slot number

sub-interface — optional sub-interface

vci — Local VCI

vpi — Local VPI

rname — Remote nodename

rslot — Remote slot

r_int — Remote interface, i.e. Switch interface number, or SM port number

r_vpi — Remote VPI

r_vci — Remote VCI

master — Local: make this RPM the master end of the connection. Type master local to make the local RPM you are configuring master. Remote (default): make the other RPM the master end of the connection. Type master remote or hit <cr> to make the far-end RPM master.

Use master local for connections to the PXM or to other SMs, or when connecting to FRSM, PXM for 2- or 3-segment connections. In a local (DAX) RPM-RPM connection, one side must be master.

Setting Up Connections Between Other Devices and the PXM

To complete a RPM-to-service module connection, you then configure the connection between the service module and the PXM.

Service Modules

Service modules can be of various types including FRSM (Frame Relay), AUSM (ATM UNI), CESM (Circuit Emulation) and VISM (Voice).

AUSM

The AUSM-8T1/E1 is a multipurpose card that supports up to 8 T1 or E1 ports.

CESM

The Circuit Emulation Service Module (CESM) emulates leased lines/circuits over an ATM network. It converts DS1/E1 or data streams into CBR AAL1 cells for transport across the network. The T1/E1 versions support either structured or unstructured data transfer on a per-physical interface basis.

VISM

VISM is a multi-DSP co-processing card and software package that adds voice over IP capabilities to the MGX 8850 platform. The MGX 8850 utilizes this new feature card along with LAN/WAN routing capabilities to provide a 192/240 channels gateway for VoIP packetized voice traffic to and from TDM traffic.

FRSM

The Frame Service Module (FRSM) is a two-card set consisting of an FRSM front card (channelized or fractional, T1 or E1, 8 port) and either an 8T1, or 8E1 port adapter. The FRSM converts Frame Relay packets into ATM cells.

Data Forwarding to RPMs

Service modules can be configured to forward data to the RPMs in one of two modes: port forwarding or connection forwarding.

Frame Aggregation: Port Forwarding (FRSM)

In this mode, all frames received on a port are forwarded to the router for L3 processing. For example, a FRSM T1 could be configured for PPP IP access by:

1. Setting up a frame forwarding (FF) connection from a FRSM T1 port to the RPM cellbus address on VPI/VCI.

2. Configuring the router to terminate PPP frames forwarded over an ATM connection on the ATM Deluxe Port Adaptor port on VCI 0/xFrame-forwarding (a proprietary method whereby all HDLC frames received on a port are converted to ATM AAL5 frames with a null encapsulation and sent over a single VC). Cisco has implemented code to terminate frame-forwarded PPP over ATM.

The data flow for a PPP connection destined for the RPM is shown in the figure below. The packet enters the FRSM module as PPP and is frame forwarded to the RPM. The RPM receives the packet in PPP over ATM because MGX 8850 internal connectivity is ATM. The RPM is running software that understands PPP over ATM encapsulation, allowing the router to reach the IP layer and route the packet to its destination (i.e. the Internet). Packets then destined to the Internet via a WAN network are then sent back to the PXM, and out the ATM uplink.

Figure 5-2 Internal Path of a PPP Packet Destined for RPM

PPP over ATM example

In this example, the FRSM is in slot 18 and RPM A is in slot 12. A serial port on Router B is connected to the FRSM line 1.

FRSM configuration (See FRSM documentation for complete command syntax):

Step 1 Configure the line. 

SQureshi.1.18.FRSM.a> addln 1

Step 2 Configure a frame-forwarding port on the line. 

SQureshi.1.18.FRSM.a> addport 1 1 2 1 24 3

Step 3 Configure a frame-forwarding channel from the port to the RPM.

Connect DLCI 1000 on the port to a unique VCI on the RPM, using VPI 0.

Connection Forwarding

In this mode all frames received on a given connection are forwarded to the router using the appropriate ATM encapsulation. For example, Frame Relay connections on a FRSM port could be forwarded to the RPM by:

•Translating a Frame Relay connection to an ATM connection or service interworking (FRF.8)

•DLCI y to the RPM cellbus address with VPI/VCI 0/x

•Configure the RPM to terminate Frame Relay to ATM connections (RFC 1483) on the ATM interface on VCI 0/x

The data flow for a native Frame Relay connection destined to the RPM is shown in Figure 5-3. This data flow is identical to that of PPP packets, but the encapsulation techniques are different. Standard Frame Relay is encapsulated using RFC1490. When a packet is received at the FRSM encapsulated using RFC1490, standard FR-ATM service interworking translation mode (FRF.8) is performed so that when the packet is forwarded to the RPM it is encapsulated using RFC1483. The router also understands RFC1483 allowing it to reach the IP layer, and route the packet.

Figure 5-3 Path of a Native Frame Relay Connection

Frame over ATM Example

In this example, the FRSM-8T1 is in slot 18 of the MGX 8850, while the RPM is in slot 12.

Frame Relay router (connected to line 1 of FRSM) configuration example: 


interface Serial0

ip address 192.168.101.2 255.255.255.0

encapsulation frame-relay IETF


***

FRSM configuration (See FRSM documentation for complete command syntax):

Step 1 Configure the line. 

SQureshi.1.18.FRSM.a> addln 1

Step 2 Configure a Frame Relay port on the line, with StrataLMI signalling. 

SQureshi.1.18.FRSM.a> addport 1 1 2 1 24 1

SQureshi.1.18.FRSM.a> xcnfport -pt 1 -sig 3

Step 3 Configure a service-interworking or network-interworking channel from the port to the RPM. Connect each DLCI on the port to a unique VCI on the RPM, using VPI 0.

ATM Service

The ATM UNI Service Modules (AUSMs) provide native ATM UNI (compliant with ATM Forum v3.0, v3.1, and v4.0) interfaces at T1 and E1 speeds, with eight ports per card, providing up to
16 Mbps of bandwidth for ATM service interfaces.

Consistent with Cisco's Intelligent QoS Management features, AUSM cards support per-VC queuing on ingress and multiple class-of-service queues on egress. AUSM cards fully support continuous bit rate (CBR), variable bit rate (VBR), unspecified bit rate (UBR), and available bit rate (ABR) service classes.

The AUSM-8 cards also support ATM Forum-compliant inverse multiplexing for ATM (IMA). This capability enables multiple T1 or E1 lines to be grouped into a single high-speed ATM port. This
N x T1 and N x E1 capability fills the gap between T1/E1 and T3/E3, providing bandwidth up to
12 Mbps (N x T1) or 16 Mbps (N x E1) without requiring a T3/E3 circuit.

A single AUSM card can provide hot standby redundancy for all active AUSM cards of the same type in the shelf (1:N redundancy).

AUSM modules are supported by standards-based management tools, including SNMP, TFTP (for configuration and statistics collection), and a command line interface. Cisco's WAN Manager application suite also provides full graphical user interface support for connection management, and CiscoView software provides equipment management.

Table 5-2 below summarizes the key attributes of the AUSM cards:

Setting Up the FRSM and CESM Connections to the PXM

The following procedure may be used for configuring the FRSM and CESM connection to the PXM. The AUSM is slightly different and is in the section, "Setting Up the AUSM Connection to PXM," later in this chapter.

Step 1 Go to the PXM and login.

Step 2 Then, cc to the slot where the service module is: 

prompt# cc 12

Step 3 Type dsplns to see interfaces: 

prompt# dsplns

Step 4 To establish the physical connection between the service module and the PXM, enable a line with the command addln: 

prompt# addln 2

Step 5 Display ports: 

prompt# dspports

Step 6 Add a port: 

prompt# addprt port_num line_num port_type

Step 7 Display ports: 

prompt# dspports

Step 8 Choose signalling type: 

prompt# xcnfport "-pt" <PortNum) -sig (type)"

<cr>

Step 9 Now configure the logical link between the service module and the PXM by typing the command addcon: 

prompt# addcon "port dlci cir chan_type [CAC] [Controller_Type][mastership] 
[remoteConnId]"

where parameters are:

port number — values ranging from 1-192 are accepted for T1 and 1-248 for E1

DLCI number — value ranging from 0 to 1023

committed rate — 0-1536000 bps for T1; 0-2048000 bps for E1

chan type — values 1-5:

–1=NIW

–2=SIW-transparent

–3=SIW-xlation

–4=FUNI

–5=frForward

CAC — Connection Admission Control (optional); 1 = enable, 2 = disable (default)

Controller Type (Signalling) — 1:PVC (PAR) - Default , 2:SPVC (PNNI)

mastership — 1 for master, 2 for slave

Remote end Connection ID — Format :

NodeName.SlotNo.PortNo.Dlci OR

NodeName.SlotNo.PortNo.ControllerId.Dlci for FR end point OR

NodeName.SlotNo.PortNo.VPI.VCI for ATM end point.

Where controller ID can be 1(PAR),2(PNNI),3(TAG)</html>l6f

Viewing FRSM, CESM and AUSM Connections Through the PXM

The following are CLI commands on the PXM, to see FRSM, CESM and AUSM connections through PXM. Whether, these are Feeder, UNI or DAX connections, the PXM command dspcons shows, all connections on the shelf. You can also, execute some commands on the service module, side to see the connection parameters (these are dspchan, dspcon etc.).

Here is a typical output of dspcons on PXM:

Configuration Examples

ATM Configuration Examples

For detailed configuration examples, refer to the router software publications listed in the first paragraph in the Preface at the beginning of this document. The following sections contain examples of ATM interface configurations:

•Example of PVCs with AAL5 and LLC/SNAP Encapsulation

•Example of PVCs in a Fully Meshed Network

For examples of emulated LAN configurations, refer to the document, MGX 8850 Wide Area Switch Installation and Configuration.

Example of PVCs with AAL5 and LLC/SNAP Encapsulation

The following example creates PVC 5 on the ATM interface 5/1 using LLC/SNAP encapsulation over AAL5. ATM interface 5/1 (IP address 1.1.1.2 255.255.255.0) connects with the ATM interface (IP address 1.1.1.1 255.255.255.0) at the other end of the connection. The static map list named atm1 declares that the next node is a broadcast point for multicast packets from IP.

Example of PVCs in a Fully Meshed Network

The configurations for RPMs A, B, and C follow. In this example, the RPMs are configured to use PVCs. Fully meshed indicates that each network node has either a physical circuit or a virtual circuit connecting it to every other network node. Note that the two map-list statements configured in RPM A identify the ATM addresses of RPMs B and C. The two map-list statements in RPM B identify the ATM addresses of RPMs A and C. The two map list statements in RPM C identify the ATM addresses of RPMs A and B. Figure 5-4 illustrates a fully meshed network.

Configuration Mode

You can configure the RPM manually if you prefer not to use AutoInstall or the prompt-driven System Configuration Dialog.

Note Refer to the section "Cisco IOS Software Basics" later in this chapter for basic information about Cisco IOS software, getting context-sensitive help, and saving configuration changes.

Take the following steps to configure the RPM manually:

Step 1 Connect a console terminal to the RPM.

Follow the instructions described in "Installing the Cisco MGX 8850 RPM," and then power ON the RPM.

Step 2 When you are prompted to enter the initial dialog, enter no to go into the normal operating mode of the RPM: 

Would you like to enter the initial dialog? [yes]: no

Step 3 After a few seconds you will see the user EXEC prompt (Router>).

By default, the host name is Router, but the prompt will match the current host name. In the following examples, the host name is MGX8850-RPM. Enter the enable command to enter enable mode. You can only make configuration changes in enable mode: 

MGX8850-RPM> enable

The prompt will change to the privileged EXEC (enable) prompt, MGX8850-RPM#.

Step 4 Enter the configure terminal command at the enable prompt to enter configuration mode: 

MGX8850-RPM# config terminal

You can now enter any changes you want to the configuration. You will probably want to perform the following tasks:

a. Assign a host name for the RPM using the hostname command.

b. Enter an enable secret using the enable secret command.

c. Enter an enable password using the enable password command.

d. Assign addresses to the interfaces using the protocol address command.

e. Specify which protocols to support on the interfaces.

Refer to the Cisco IOS configuration and command reference publications for more information about the commands you can use to configure the RPM. You can also refer to the MGX 8850 Wide Area Switch Command Reference and MGX 8850 Wide Area Switch Installation and Configuration documents for information about the commands you can use to configure the RPM.

Step 5 When you finish configuring the RPM, enter the exit command until you return to the privileged EXEC prompt (MGX8850-RPM#).

Step 6 To save the configuration changes to NVRAM, enter the copy running-config startup-config command at the privileged EXEC prompt: 

MGX8850-RPM# copy running-config startup-config

********

The RPM is now configured and will boot with the configuration you entered.

This concludes the initial RPM configuration.

Verifying Network Connectivity

When you have installed and configured the RPM, you can use the following commands in user EXEC mode to verify network connectivity:

•ping—Sends a special datagram to the destination device, then waits for a reply datagram from that device

•telnet—Logs in to a remote node

•trace—Discovers the routes that packets take when traveling from one RPM to another

If there is a problem with network connectivity, refer to "Maintaining the Cisco MGX 8850 RPM," and check the cable connections. If there is still a problem, check the RPM configuration. Contact customer service for further assistance.

Specifying the Boot Method

You can enter multiple boot commands in the configuration in NVRAM to provide a backup method for loading the Cisco IOS image onto the RPM. The RPM boots using the first boot command that succeeds. If you enter multiple boot commands, the RPM executes them in the order they are entered. There are two ways to load the Cisco IOS image: from the PXM hard drive or from a TFTP server on the network.

1. PXM Hard Drive

Information stored in HD is not vulnerable to network failures that might occur when you load system software from servers. In the following example, replace filename with the filename of the Cisco IOS image: 

MGX8850-RPM> enable

Password: enablepassword

MGX8850-RPM# configure terminal

MGX8850-RPM (config)# boot system c:filename

MGX8850-RPM (config)# Ctrl-Z

MGX8850-RPM# copy running-config startup-config

Building configuration ...

[OK]

MGX8850-RPM# exit

MGX8850-RPM>

2. TFTP server

If the PXM hard drive does not contain a valid Cisco IOS image, you can specify that system software be loaded from a TFTP server on your network as a backup boot method for the RPM. In the following example, replace filename with the filename of the Cisco IOS image, and replace ipaddress with the IP address of the TFTP server: 

MGX8850-RPM> enable

Password: enablepassword

MGX8850-RPM# configure terminal

MGX8850-RPM (config)# boot system tftp filename ipaddress

MGX8850-RPM (config)# Ctrl-Z

MGX8850-RPM# copy running-config startup-config

Building configuration ...

[OK]

MGX8850-RPM# exit

MGX8850-RPM>

3. PXM C: drive

The RPM has access to the file system on the PXM C:drive, in the C:RPM directory. Use the Console port on the RPM to boot the RPM from Flash so that you configure its ATM switch interface as no shutdown. This then lets you access the c: drive on the PXM and copy files to the startup config or to bootflash.

In the following example, replace filename with the filename of the Cisco IOS image. Type the following commands to boot the RPM from the PXM and copy files: 


MGX8850-RPM> enable 

Password:enablepassword 

MGX8850-RPM# configure terminal 

MGX8850-RPM (config)# boot system c:filename 

MGX8850-RPM (config)# Ctrl-Z 

MGX8850-RPM# copy running-config startup-config 

Building configuration ... 

[OK] 

MGX8850-RPM# 


*****

Then reload the RPM to get back to rommon and then boot full IOS from the PXM disk.

Note Put the RPM IOS image in the RPM directory of the PXM hard disk with the filename specified in the RPM boot command.

Cisco IOS Software Basics

This section provides you with some basic information about the Cisco IOS software and includes the following sections:

•Cisco IOS Modes of Operation

•Getting Context-Sensitive Help

•Saving Configuration Changes

Cisco IOS Modes of Operation

Cisco IOS software provides access to several different command modes. Each command mode provides a different group of related commands.

For security purposes, Cisco IOS software provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.

Table 5-3 describes some of the most commonly used modes, how to enter the modes, and the resulting prompts. The prompt helps you identify which mode you are in and, therefore, which commands are available to you.

Table 5-3 Cisco IOS Operating Modes

Mode of Operation
Usage
How to Enter the Mode
Prompt

User EXEC

User EXEC commands allow you to connect to remote devices, change terminal settings on a temporary basis, perform basic tests, and list system information. The EXEC commands available at the user level are a subset of those available at the privileged level.

Log in.

MGX8850-RPM>

Privileged EXEC

Privileged EXEC commands set operating parameters. The privileged command set includes those commands contained in user EXEC mode, and also the configure command through which you can access the remaining command modes. Privileged EXEC mode also includes high-level testing commands, such as debug.

From user EXEC mode, enter the enable EXEC command.

MGX8850-RPM#

Global configuration

Global configuration commands apply to features that affect the system as a whole.

From global configuration mode, enter the configure privileged EXEC command.

MGX8850-RPM(config)#

Interface configuration

Interface configuration commands modify the operation of an interface such as an Ethernet or serial port. Many features are enabled on a per-interface basis. Interface configuration commands always follow an interface global configuration command, which defines the interface type.

From global configuration mode, enter the interface type number command. For example, enter the interface int switch 9/1 command to configure the ATM interface.

MGX8850-RPM(config-if)#

ROM monitor

ROM monitor commands are used to perform low-
level diagnostics. You can also use the ROM monitor commands to recover from a system failure and stop the boot process in a specific operating environment.1

From privileged EXEC mode, enter the reload EXEC command. Press Break during the first 60 seconds while the system is booting.

>

1 You can modify the configuration register value using the config-reg configuration command. Refer to "Maintaining the Cisco MGX 8850 RPM," for more information.


Almost every configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. For example, IP routing is enabled by default. To disable IP routing, enter the no ip routing command and enter ip routing to reenable it. The Cisco IOS software command reference publication provides the complete syntax for the configuration commands and describes what the no form of a command does.

Getting Context-Sensitive Help

In any command mode, you can get a list of available commands by entering a question mark (?). 

MGX8850-RPM> ?

To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.

To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.

You can also abbreviate commands and keywords by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the show command to sh.

Saving Configuration Changes

Whenever you make changes to the RPM configuration, you must save the changes to memory so they will not be lost if there is a system reload or power outage. There are two types of configuration files: the running (current operating) configuration and the startup configuration. The running configuration is stored in RAM; the startup configuration is stored in NVRAM.

To display the current running configuration, enter the show running-config command. Enter the copy running-config startup-config command to save the current running configuration to the startup configuration file in NVRAM. 

MGX8850-RPM> enable

MGX8850-RPM# copy running-config startup-config

To display the startup configuration, enter the show startup-config command. Enter the copy startup-config running-config command to write the startup configuration to the running configuration. 

MGX8850-RPM> enable

MGX8850-RPM# copy startup-config running-config

To erase both configuration files (and start over), enter the write erase and reload commands: 

MGX8850-RPM> enable

MGX8850-RPM# write erase

MGX8850-RPM# reload

Warning This command sequence will erase the entire RPM configuration in RAM and NVRAM and reload the RPM.
