The "System Initialization" chapter explains how to initialize the Cisco 6100 so ViewRunner for HP OpenView can be used to provision and operate the system.
In order for a proper communication path to exist between the Cisco 6100 and ViewRunner for HP OpenView, the Cisco 6100 must be initialized as follows:
The above IP addresses can be established at system initialization time through one of three methods:
1. Cisco factory initialization
2. BOOTP utility
3. System Controller (SC)-based BOOTROM initialization utility
Each of these alternatives is discussed in detail below.
The simplest methodology for initializing a Cisco 6100 is for Cisco personnel to pre-configure the Cisco 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 insuring that all necessary system initialization is in place prior to equipment arrival at the customer premise. It is sometimes viewed as less attractive, however, as it assumes critical IP address information is both correctly communicated 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 standalone machine that is directly attached to the Cisco 6100 Ethernet port (temporarily) for the sole purpose of system initialization.
Each time the Cisco 6100 is powered up, or each time the SC is reset, the SC issues a BOOTP request. 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 HP OpenView machine with its own copy of a BOOTP server utility), this standalone BOOTP server (locally attached to the Cisco 6100'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 HP OpenView machine, and would also need to contain the BOOTP table information (above) necessary to configure the target Cisco 6100.
A network connection through a no-hub cable between this machine and the Cisco 6100 is required to initialize the Cisco 6100. The Cisco 6100 would go through the same initialization sequence as described above, and would be configured by the locally attached BOOTP server. Once the initialization procedure is complete, the standalone BOOTP server would need to be disconnected from the Cisco 6100's Ethernet port. Subsequently, the Ethernet connection to the local area network for which the Cisco 6100 has been configured must be connected. Should the Cisco 6100's SC require a new image download at some point in the future, this manual configuration process will have to be repeated.
In those situations where it is not possible to create a single virtual network to connect each
Cisco 6100 to ViewRunner for HP OpenView, 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 (see the Cisco 6100 Set Up and Installation Manual for a description of this 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:

Error: Values not stored to EEPROM due to IP setup error. Are you ready to continue? [Y]
If a Cisco 6100 is properly connected to the network, it will receive a BOOTP response from the ViewRunner for HP OpenView workstation. It will then download a new image if necessary from the TFTP server, and issue a cold start trap to the TFTP server, which should be the ViewRunner workstation. If it is the ViewRunner workstation, then ViewRunner will receive the cold start trap, display the appropriate entries in the Event Browser, and add the Cisco 6100 to the New Equipment window. An informational dialog will appear informing the user that a Cisco 6100 has been discovered.
Once you have initialized the system, set the system clock so that each system message has an accompanying time-stamp. To set the system clock, follow the steps below:
Step 1 Right click on the MC. The Cisco 6100 menu appears. Select the 6100 Properties >> Configuration option.
The 6100 Properties window appears.
Step 2 Set the date and time by clicking on the appropriate field. A drop down menu appears in each field with multiple selections.
Using the inband management channel feature of the ViewRunner for HP OpenView 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.
1. Access the main Chassis View.
2. Move your cursor over the chassis, and click the right mouse button. The following pop-up menu appears:
3. Select Inband Management Channel and the following window appears.
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.
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.
1. Access the main Chassis View.
2. Move your cursor over the chassis, and click the right mouse button. The following pop-up menu appears:
3. Select Routing Table and the following window appears.
4. Set the Interface to Inband Channel.
5. Enter the IP address of the packet destination, its gateway IP address, and its submask. 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.
