This section explains how to initialize a Cisco 6100 so ViewRunner for Windows can communicate with it. You should be familiar with the BOOTP utility and TFTP to use these initialization processes.
To establish a proper communication path between the Cisco 6100 and ViewRunner for Windows, initialize the Cisco 6100 as follows:
The system controller (SC) stores the IP information for the Cisco 6100.
The above IP addresses establish at system initialization time through one of three methods:
The following sections discuss each of these methods in detail.
The simplest method for initializing a Cisco 6100 is for Cisco personnel to pre-configure the 6100 with the appropriate IP address information prior to customer shipment. This requires the customer to provide Cisco with the IP address information listed above in advance. As such, this approach requires careful coordination between Cisco and the customer to ensure that all customer-supplied IP address information is correct.
The factory initialization option has the advantage of ensuring that all necessary system initialization is in place prior to equipment arrival at your site.
 | Tips Factory initialization assumes critical IP address information is correct and will not change. |
BOOTP is a commercially available utility that allows IP address initialization through a BOOTP server, often already resident in communication network infrastructures.
A Cisco 6100 can be initialized with a BOOTP server in one of two ways. Either the BOOTP server can be on a machine located on the same virtual network as the Cisco 6100, or it can be resident on a stand-alone machine that is directly attached (temporarily) for the sole purpose of system initialization.
The SC issues a BOOTP request each time the Cisco 6100 powers up or the SC resets. At this point, the Cisco 6100's SC becomes a BOOTP client.
The BOOTP server responds to the client request with the following items:
Included as part of this response is the IP address of the machine answering the BOOTP request.
Once the SC receives the BOOTP response, it compares the supplied filename with the filename stored locally in its EEPROM. If the two filenames differ, the SC requests the new file (using TFTP), and downloads the file from the TFTP server. The SC stores the new image in Flash, overwriting the previous image. If the file names are the same or if no reply is received from the BOOTP server, the SC loads and runs the existing image contained in its Flash memory.
If only one machine is available as a BOOTP server (as opposed to equipping each ViewRunner for Windows machine with its own copy of a BOOTP server utility), this stand-alone BOOTP server (locally attached to the Cisco 6100 system's Ethernet port) can be used to initialize each Cisco 6100's IP address requirements. During the initialization procedure, this machine would need to be given the same IP address as the eventual ViewRunner for Windows machine. It would also need to contain the BOOTP table information necessary to configure the target Cisco 6100.
A network connection through a no-hub cable between the BOOTP server and the Cisco 6100 is required to initialize the Cisco 6100. You initialize the Cisco 6100 through standard initialization procedures and use the locally attached BOOTP server to configure it. Once the initialization procedure is complete, disconnect the stand-alone BOOTP server from the Cisco 6100's Ethernet port. Then, connect the Ethernet port to the local area network (LAN) for which the Cisco 6100 has been configured.
In those situations where it is not possible to create a single virtual network to connect each Cisco 6100 to ViewRunner for Windows, or factory initialization is not preferred, you can use a Cisco developed, menu-driven BOOTROM initialization utility attached to the RS-232 port.
Using this utility eliminates the need for BOOTP altogether.
The BOOTROM Administrative Setup screen is activated in one of two ways. The menu automatically is activated anytime a serious error is detected during the boot process, such as an NVRAM test failure. The menu also activates during an error-free boot by entering carriage returns at one-per-second starting at the point of hardware reset.
To access the Administrative Setup screen requires a PC to be directly connected to the SC RS-232 serial port with a standard 9-pin D-sub cable. Use standard RS-232 settings:
Use a terminal emulation package, such as Microsoft's Hyperterminal, or Procomm, to perform the initialization procedures.
Step 1 Press Enter in one second intervals until the Administrative Setup screen appears:

Step 2 Select Option 2. The modify IP address option allows the setup of the IP address of the Cisco 6100's SC.
The prompt screen shall appear as follows:
CAUTION: Entered data not saved until save option has been
executed. All changes shall be lost if exit is executed before save option. Enter IP Address: [192.168.7.41]
If the value contained in the brackets [] is correct, press Enter to accept the default value. To enter a new value, type in value in the xxx.xxx.xxx.xxx format. After entering the new IP address, press Return. The Administrative Setup screen appears.
If the entered value is not correct, an error message may be generated. For more information on this topic, see the IP setup error message section.
Step 3 Select Option 3. The modify IP subnet mask option allows the setup of the IP subnet mask through the Administrative Setup screen.
The prompt screen shall appear as follows:
CAUTION: Entered data not saved until save option has been
executed. All changes shall be lost if exit is executed before save option. Enter Subnet mask: [255.255.255.0]
If the value contained in the brackets [] is correct, press Enter to accept the default value. To enter a new value, enter the value in the xxx.xxx.xxx.xxx format and press Return, which will return you to the Administrative Setup screen.
If entered value is not correct, an error message may be generated. For information on this topic, see the IP setup error message section.
Step 4 Select Option 4. The Modify IP Gateway Address option allows the setup of the IP gateway through the Administrative Setup screen.
The prompt screen shall appear as follows:
CAUTION: Entered data not saved until save option has been executed. All changes shall be lost if exit is executed before save option. Enter IP Gateway: [192.168.7.231]
If the value contained in the brackets [] is correct, press Enter to accept the default value. To enter new value, enter the value in the xxx.xxx.xxx.xxx format and press Return, which will return you to the Administrative Setup screen.
If entered value is not correct, an error message may be generated. For information on this topic, see the IP setup error message section.
Step 5 Select Option 6. The Save IP values to EEPROM option modifies the contents of the EEPROM with any data that has been changed during this session. It also updates the checksum for the administrative area. Verification of Basic IP integrity occurs prior to saving. If integrity is not found, an error message displays and no modification of EEPROM data occurs. Potential error messages are as follows:
IP 0.0.0.0 or 255.255.255.255 Error
The IP setup processing does a basic verification of the IP setup. It assures that the IP address is not set to 0.0.0.0 or 255.255.255.255. It also assures that the IP address and IP gateway address appear on the same subnet as defined by the subnet mask.
Error: Ip Address should not be 0.0.0.0 or 255.255.255.255 Do you wish to correct value? [Y]
IP Address and Gateway Subnet Mismatch Error
Error: Ip Address and Ip Gateway do not appear on same subnet. Ip Address, Ip Gateway, or Ip Subnet Mask is invalid. Do you wish to correct value? [Y]
Save Data IP Error
Error: Values not stored to EEPROM due to IP setup error. Are you ready to continue? [Y]
Step 6 Select Option 0 to exit. If any changes were performed to the IP addressing in setup, enter Y at this prompt: Hardware Reset? [Y]. If no changes were made, select [N].
 | Caution Entering N could result in IP communication problems before the card resets. |
After the Cisco 6100 is initialized, only the SC will have an image. You should now be able to discover the Cisco 6100 using ViewRunner for Windows and using the "Upgrade Cisco 6100 Software" option to download images to the remaining modules.
Refer to the ViewRunner for Windows Provisioning and Operation Guide for more information on the software download. This software download feature is used not only to upgrade but also to continue initializing the Cisco 6100.
The Cisco 6100 is properly configured when the ViewRunner for Windows Chassis View discovers the Cisco 6100 equipment and displays a graphical representation of the Cisco 6100 to your PC screen. You activate ViewRunner auto-discovery by selecting the icon for discover or the menu option Discover Cisco 6100, or you can have ViewRunner automatically execute auto-discovery by selecting that option in ViewRunner Preferences. See "ViewRunner Settings," for details.
Using the inband management channel feature of the ViewRunner for Windows allows direct control/management of the Cisco 6100 through the ATM channel. The inband management channel is transparent to ViewRunner in that provisioning and operation of the system are identical whether through the ethernet port or the inband channel. The only difference is that instead of using conventional ethernet physical media to communicate to the Cisco 6100, ViewRunner will use ATM as the physical layer for communication.
To run IP over ATM, the system uses RCF 1483 "Multi-protocol over AAL5" in Logical Link Control (LLC) encapsulation mode. This encapsulation will allow transporting via multiple protocols over a single VC. The following figure illustrates how the inband management channel works.
To make sure the out-bound packets from the Cisco 6100 are sent to the right interface (ethernet or inband), a routing table for various IP addresses is also supported. This table is only needed when you use the inband management channel. Ethernet takes care of its own routing.
To use the inband management channel rather than ethernet, follow the procedures below.
Step 1 Access the main Chassis View.
Step 2 Move your cursor over the chassis, and click the right mouse button. The following pop-up menu appears:
Step 3 Select Inband Management Channel and the following window appears.
Step 4 Enter the IP address of the inband port and its submask. Then specify the VPI/VCI to be used for the communication channel.
The Administrative state must be Locked for you to enter the IP and VPI/VCI information. Once you have entered this information the note at the bottom of the window disappears and the buttons become active. Press Apply and then Unlocked to activate the configuration. All fields will be grayed out then unless you set the Administrative state back to Locked to change the information.
ViewRunner for Windows supports software downloads and restores for Cisco 6100 nodes being managed via the inband management channel or the ethernet management channel. The menu option allowing this feature is active only if the SC supports the feature and the node is being managed through one of the management channels.
The following are things that you should consider when using the inband management channel.
It is not necessary to use the routing table if you are using ethernet as the method for managing a Cisco 6100. However, a routing table is necessary with inband management so that the Cisco 6100 can send the out-bound packets to the right interface. Otherwise, the return packets would never reach their destination.
To add IP addresses to the routing table when using the inband management channel rather than ethernet, follow the procedures below.
Step 1 Access the main Chassis View. Move your cursor over the chassis, and click the right mouse button. The following pop-up menu appears:
Step 2 Select Routing Table and the following window appears.
Step 3 Set the Interface to Inband Channel.
Step 4 Enter the IP address of the packet destination, its gateway IP address, and its submask. Note that the destination address is the subnet address and not a host address. Then select Add Now.
Should you want to change the destination IP address, simply navigate back to this window, select a destination from the top field and select Delete Now to delete an address. Then add a different one following the procedures presented previously.
The following are things that you should consider when establishing the routing table.
