Configuring the MGX RPM-PR
This chapter describes how to complete a basic configuration of the MGX Route Processor Module
(RPM-PR). It provides procedures for configuring ATM, Ethernet, and Fast Ethernet interfaces, as well
as, permanent virtual circuits (PVCs). It also details how to make connections between an RPM-PR and
a PXM-45 and between other service modules or other RPM-PRs. The chapter contains the following
sections:
•
Accessing the RPM-PR Command Line Interface
•
Booting the RPM-PR
•
Verifying the Configuration
•
Establishing 1:N Redundancy Between Two or More RPM-PR Cards
This chapter provides information necessary to get the RPM-PR up and running. Detailed command
information is available in the Cisco IOS command reference publications.
Note
The back cards used in conjunction with the RPM-PR are equivalent to port adapters in Cisco routers.
Accessing the RPM-PR Command Line Interface
To configure the RPM-PR, you must access the command line interface (CLI) of the RPM-PR.
The RPM-PR CLI can be accessed using any of the following methods:
•
Console port on the front of the RPM-PR
The RPM-PR has an RJ-45 connector on the front of the card module. If you configure the RPM-PR
on site, connect a console terminal (an ASCII terminal or a PC running terminal emulation software)
directly to the console port on your RPM-PR using an RS-232 to RJ-45 rollover cable for CLI access
(see Chapter 3, “Installing the MGX RPM-PR”).
•
cc from another MGX 8850 or MGX 8950 card
After initial configuration, you can also configure the RPM-PR through the PXM-45. You access the
RPM-PR CLI by entering the cc (change card) command from any of the other cards in the switch.
•
Telnet from a workstation, PC, or another router
After initial configuration, you can also configure the RPM-PR remotely via Telnet. After the
RPM-PR is installed and has PVCs to other RPM-PRs or routers in the network, you can Telnet to
access the RPM-PR CLI remotely from these other devices.

Chapter 5
Configuring the MGX RPM-PR
Booting the RPM-PR
To connect a modem to the auxiliary port on the RPM-PR, see Chapter 3, “Installing the MGX
RPM-PR.”
Booting the RPM-PR
When the RPM-PR is booted, the boot image must be the first file in the bootflash. If the bootflash does
not have a valid boot image as a first file, the card may not be able to boot and can result in bootflash
corruption. If the bootflash is corrupted, you will have to send the card back for an external burn with a
valid boot image.
You can reboot the RPM-PR from the PXM by entering the command resetcd <card_number> from the
switch CLI, where card_number is the slot number of the RPM-PR that is being rebooted.
Note
Omitting the card number resets the entire system.
Also, you can reboot the RPM-PR from the RPM-PR using the RPM-PR console port and entering the
reload command.
Each time you turn on power to the RPM-PR, by inserting the RPM-PR into the MGX 8850 or the
MGX 8950, it goes through the following boot sequence:
1.
The RPM-PR runs diagnostics on the CPU, memory, and interfaces.
2.
The system boot software, which is the boot image, executes and searches for a valid Cisco IOS
image, which is the RPM-PR runtime software.
The source of the Cisco IOS image is determined by the configuration register setting. To verify this
setting, you can enter either the show version or show bootvar command. (See the “Viewing the
Hardware Configuration” section later in this chapter.)
•
If the configuration register is set to the factory-default setting of 0x01, RPM-PR will come up and
stay in boot mode.
•
If the configuration register is 0x2, the RPM-PR will look for the runtime image either in bootflash
or on the PXM C:FW drive.
3.
The search for runtime image is determined by which boot system command is entered.
•
Entering the boot system x:<runtime_image_name> command will result in a search for a runtime
image on the PXM C:FW drive.
•
Entering the boot system bootflash:<runtime_image_name> command will result in a search for a
run time image in the bootflash.
4.
If the runtime software is not found after three attempts, the RPM-PR reverts to the boot mode.
5.
If a valid Cisco IOS image is found, then the RPM-PR searches for a valid configuration, which can
reside in NVRAM or as a configuration file either on the PXM hard disk x: drive or in bootflash.
If you want to load from a specific configuration file, you should enter either the
boot config bootflash:<config_file> command or the boot config x:<config_file> command.
6.
For normal RPM-PR operation, there must be a valid Cisco IOS image on the PXM-45 x: drive or
in bootflash, and a configuration in NVRAM or configuration file in bootflash or on the PXM disk.
The first time you boot the RPM-PR, configure the RPM-PR interfaces and save the configuration
to a file in NVRAM. Then follow the procedure described in “Initializing the RPM-PR Card.” For
information on the Cisco IOS instructions, see Appendix C, “IOS and Configuration Basics.”

RPM-PR Bootflash Precautions
The RPM-PR bootflash is used to store boot image, configuration and “run time” files. The Flash stores
and accesses data sequentially, and the RPM-PR boot image must be the first file stored to successfully
boot the card. Erasing the boot image or moving it from the first position on the Flash will cause the card
to not boot.
The RPM boot image, which comes loaded on the Flash, will work for all RPM IOS images. Therefore,
there is no reason to ever delete or move the factory installed boot image.
Note
Erasing or moving the boot image can cause RPM-PR boot failure. When this happens, the RPM must
be returned to Cisco and reflashed.
In order to avoid this unnecessary failure, requiring card servicing, you should
•
Never erase the boot file from the RPM Flash
•
Never change the position of the boot file on the RPM Flash
•
Use care when “squeezing” the Flash to clean it up.
As long as the boot file remains intact in the first position on the flash, the RPM will successfully boot.
Verifying the IOS Files on Bootflash
Enter the show bootflash command to verify the IOS files on the bootflash. The following screen
displays the RPM-PR command sequence.

Verifying the IOS Files on the PXM-45 x: Drive
The IOS image can be stored on the PXM-45 hard drive. To confirm this, make sure you are in the C:FW
directory. Enter the ll command to list the contents of the directory. You should see a file with a name
beginning with rpm-js-mz, which is the IOS image.
Tip
Copy the RPM-PR Cisco IOS image into the RPM C: directory (not the E: directory) of the PXM-45
hard disk with the filename specified in the RPM-PR boot command.
The following screen displays the PXM C:FW content listing.

Configuring Ethernet Interfaces
Once back card cable connections are made (see Chapter 4, “Cabling the MGX RPM-PR Back Cards”
for connector descriptions and cable attachment instructions) and basic configuration on the RPM-PR is
completed, you can configure Ethernet and Fast Ethernet interfaces.
Preparing to Configure Ethernet Interfaces
To configure interfaces in a new RPM-PR or change the configuration of an existing interface, you need
to know the following information:
•
Internet protocol (IP) address for each interface
•
Network mask for each interface
•
Full or half-duplex connection
•
MGX-RJ45-FE connectors—MII or RJ-45
•
MGX-MMF-FE connectors—MII or SC

Back Card Bay and Interface Port Numbers
This section describes how to identify the back card bay and interface port numbers on the RPM-PR for
all back card interface types.
Physical port addresses specify the physical location of each interface port, regardless of the type, on the
RPM-PR. In the RPM-PR, this address is composed of a two-part number in the form
<interface bay number/interface port number>, as follows:
•
<interface bay number> identifies the bay in which the back card is installed, either upper (1) or
lower (2) bay.
•
<interface port number> identifies the interface port(s) on the back card. FE cards have one
interface number. 4E/B cards have four numbered interfaces.
For example, the following command specifies interface port 1 of the upper Ethernet back card in the
RPM-PR. You need to enter this information to select a specific port on a back card or ATM interface.
Router(config)#interface fastEthernet 1/1
Also, you can identify interface ports by checking the bay/interface port location on the body of the
RPM-PR or by using show commands to display information about a specific interface or all interfaces
in the RPM-PR.
Configuring IP Addresses and Starting Ethernet Interfaces
The following steps describe how to configure IP address on the 4E/B Ethernet and the FE Fast Ethernet
interfaces and how to start them up. Press Return after each step unless otherwise noted.
Note
Step 1
RPM-PR no longer supports the MGX-RJ45-4E Ethernet interface back card. You must use an
MGX-RJ45-4E/B Ethernet card with Release 2.1 or later.
At the privileged-level prompt, enter the command global configuration mode as follows:
Router#configure terminal
Enter configuration commands, one per line.
Step 2
End with CNTL/Z.
To specify the interface to be configured, enter the following interface subcommand at the prompt.
interface <ethernet | fastethernet> <bay>/<port>
Parameter
Description
<ethernet | fastethernet>
Interface type to be configured.
<bay>
Back card location; 1=upper and 2=lower back card
<port>
Port number on the back card
Note
The 4E/B interfaces are numbered 1, 2, 3, 4, not 0, 1, 2, 3 as in other IOS platforms.
This example is for the upper (1) Ethernet back card in the RPM-PR in slot 11 of the switch. In this
example, we configure a Fast Ethernet interface. The procedure you use to configure an Ethernet
interface is identical except for specifying the Ethernet interface type.

interface characteristics.
Step 5
Start up the Ethernet interface by entering the following command:
Router(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, type end
or press Ctrl-Z to exit configuration mode.
Step 8
Save your configuration changes as follows:
Router#copy run start
Selecting Half-duplex or Full-duplex Ethernet Communications
Half-duplex operation is the default transmission mode for the FE back cards. The following steps
describe how to configure full-duplex ethernet communications.
Step 1
Enter the full-duplex command to configure full-duplex operation for the FE back cards.
Router>enable
Password:
Router#config t
Enter configuration commands, one per line.
Router(config)#interface fastethernet 1/1
Router(config-if)#full-duplex
Router(config-if)#end
Step 2
End with CNTL/Z.
Enter the show interfaces fastethernet command to verify that the 2/1 Fast Ethernet interface is now
configured for full-duplex operation.

Step 3
Enter the show running-config command to display the running configuration file.
Step 4
Enter the show startup-config command to display the configuration stored in NVRAM.
Verify that the configuration is accurate for the system and that each interface is the same. If they are
different from running-config, you may have forgotten to enter a copy run start command.
If the interface is down and you have configured it to be up, or if the displays indicate that the hardware
is not functioning properly, be sure 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-PR, or you can order printed copies.
Viewing the Hardware Configuration
The show version (or show hardware) command displays the configuration of the system hardware, for
example, the number of each back card type installed, the software version, the names and sources of
configuration files, and the boot images.
Note
You may not be able to view hardware configuration information using show version from a remote
location.

See the next section, “Verifying Ethernet Connectivity,” to verify that each interface port is functioning
properly.
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.
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:

If the connection fails, verify that you have the correct IP address for the remote device and that the
remote device is active (powered on). Then repeat the ping command.
Establishing 1:N Redundancy Between Two or More RPM-PR
Cards
RPM-PR cards support 1:N redundancy, whereby one RPM-PR card can be configured as a redundant
or secondary (backup) card for one or multiple primary RPM-PR cards, forming a redundant group.
There can be multiple redundant groups in one shelf. RPM-PR 1:N redundancy is a cold redundancy, in
which the configuration of a failed primary card is copied to the standby secondary card. All traffic to
and from the primary RPM-PR card is switched to the secondary card after it becomes active. Because
this is a cold redundancy solution, service interruption is expected. As with other service modules, the
layer 2 state is restored when the secondary card becomes active. However, RPM-PR also performs layer
3 functionality, such as maintaining routing tables. The routing tables are created manually or by routing
protocols, such as IGRP, BGP, or OSPF. Because routing protocols are used, the layer 3 state is restored
within three to five minutes, depending on the protocol used.
RPM-PR 1:N redundancy supports the following features:
•
Increases availability by decreasing the DPM of the network by reducing boot-up, switchover, and
upgraded times.
•
Supports L2 redundancy and restores L3 state via reconvergence.
•
Support for up to 11 active (primary) RPM-PRcards per single redundant (standby or secondary)
RPM-PR.
•
Support for a maximum of 6 redundant groups per MGX 8850 or MGX 8950.
The redundant card must be present and active and must not have any connections configured. Any
connection configuration will cause the addred command to be rejected.
To establish a backup card for an RPM-PR card, use the following procedure.
Step 1
Logon to the switch.
Step 2
If you have not done so already, initialize both cards as described earlier in this chapter in “Initializing
the RPM-PR Card.”
Step 3
Enter the dspcds command to verify that the primary and secondary RPM-PR card are in the “Active”
state.
Step 4
Enter the addred command.
Switch.7.PXM.a > addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
Parameter
Description
<redPrimarySlotNum>

Step 5
After you enter the addred command, the switch resets the secondary card; therefore, the
secondary card will be unavailable for a few minutes.
When the reset is complete, enter the dspcds command to show the primary and secondary cards in the
active and standby states, respectively.
The redundant RPM cards are shown in slots 2 and 11 with the standby card in slot 11.

Configuring the MGX RPM-PR
Establishing 1:N Redundancy Between Two or More RPM-PR Cards
Note
The standby card must not have any configurations and must not be configured. Therefore, do not
provision the standby card.
Using Softswitch to Change the Active Card
Enter the softswitch command to manually change the active card to the standby card. You may want to
do this if you need to remove the original active card from the MGX8850/8950 shelf. Before you begin
this procedure, make sure that the destination card is in Standby mode. To change the active cards, follow
the steps below, in which the primary or active card in slot 2 is switched to standby or secondary, and
the standby card in slot 11 is switched to primary or active.
Step 1
Enter the softswitch command.
Unknown.7.PXM.a > softswitch 2 11
softswitch: Do you want to proceed (Yes/No)? y
where 2 is the active or primary card and 11 is the standby or secondary card.
The card in slot 11 is now the active RPM-PR card, and the RPM-PR card in slot 2 is reset. It comes up
in standby mode after a couple of minutes.
The new active card will not revert to standby mode automatically. Enter softswitch to manually switch
over the active card back to standby mode. This is the only way the active card will switch over to
standby, unless the active card fails.
Step 2
Enter the same command to switch the active card back to the original RPM-PR.
Unknown.7.PXM.a > softswitch 11 2
softswitch: Do you want to proceed (Yes/No)? y
where 11 is now the active card and 2 is now the standby/secondary card.
Deleting Redundancy
To delete card redundancy, the primary card must be active, otherwise this command will be rejected.
Enter delred followed by the primary card’s slot number, as shown here:
Switch.7.PXM.a > delred 2
Redundancy link is deleted
The secondary card is reset and comes back up as an active normal RPM-PR card (if it is the last primary
card) that can be used for any other purpose. Note in the example below that the card in slot 11 is now
active.

Adding Additional Primary Cards
You can add one or more additional RPM-PR cards as primary cards backed up by the secondary card.
To do this, enter the addred command as follows.
Switch.7.PXM.a > addred <redPrimarySlotNum> <redSecondarySlotNum> <redType>
Repeat this step for each additional card you want to add to the secondary card backup protection. In the
following example, the primary cards in slots 2, 3, and 4 are being backed up by the secondary RPM-PR
in slot 11.
switch.7.PXM.a > addred 2 11 2
switch.7.PXM.a > addred 3 11 2
switch.7.PXM.a > addred 4 11 2
Upgrading Redundant RPM-PR Cards
The following procedure describes how to upgrade redundant RPM-PR cards.
Note
Redundancy must be established as described above, before you use this procedure.
Step 1
On the primary active RPM-PR card, modify the running configuration to boot from the new upgrade
software.
Step 2
Enter WR MEM to execute the write memory command, which saves the configuration.
Step 3
Enter the softswitch command, as follows, to switch to the secondary card.
switch.7.PXM.a > softswitch <fromSlot> <toSlot>
This step makes the secondary card active and resets the primary RPM-PR card. When the primary card
resets, it loads the upgraded software defined in Step 1.
Step 4
Modify the configuration of the secondary card to boot from the new upgrade software and enter WR
MEM to save the configuration.
Step 5
Enter the softswitch command, as follows, to switch to the primary card from secondary card. This
command is executed only after the primary card has booted and is in the standby state.
switch.7.PXM.a > softswitch <fromSlot> <toSlot>
This step makes the upgraded primary card active and resets the secondary card. When the reset is
complete, the secondary card runs the upgrade software and is now in the standby state.

e:auto_config_<slot#> command or by saving it in NVRAM by entering the WR MEM command.
Step 2
Modify the running configuration to boot from the new upgrade software by entering the boot system
command.
Step 3
Enter WR MEM to save the configuration.
Step 4
Reset the RPM-PR card by entering the reset command from the PXM or the reload command from the
RPM-PR.
