Chapter 3 Using CyROS Menus

This chapter explains CyROS menu navigation and special keys. There are four ways to interact with CyROS:

• Traditional menu interface using a console or Telnet session,

• CyROS Management Utility based on interactive HTML pages,

• SNMP (explained in the CyROS Reference Manual).

Connection Using the Console Cable and a Computer or Terminal

The first step is to connect a computer or terminal to the router using the console cable. If using a computer, HyperTerminal can be used in the Windows operating system or Kermit in the Unix operating system. The terminal parameters should be set as follows:

• Serial Speed: 9600 bps

• Data Length: 8 bits

• Parity: None

• Stop Bits: 1 stop bit

• Flow Control: Hardware flow control

FIGURE 3.1 LOGIN PROMPT AND MAIN MENU

Chapter 3 - Using CyROS Menus 14

Cyclades-PR2000

Once the console connection is correctly established, a Cyclades banner and login prompt should appear on the terminal screen. If nothing appears, see the first section of the troubleshooting appendix for help. The second step is to log in. The preset super-user user ID is “super” and the corresponding preset password is “surt”. The password should be changed as soon as possible, as described in chapter 10 of the installation manual and at the end of every example in chapter 4. The login prompts and main menu are shown in Figure

3.1. All menus have the following elements:

• Title – In the example in Figure 3.1: “Main Menu”.

• Prompt – The text: “Select Option ==>”.

• Options –The menu options, which are selected by number.

• Router Name – The default is the name of the product. Each router can be renamed by the super user for easier identification.

Menus can also be navigated using a short-cut method. This method must be activated first by choosing a shortcut character (“+” in the example that follows) in the CONFIG =>SYSTEM =>ROUTER DESCRIPTION menu. Typing 4+1+1 at the main-menu prompt, for example, is equivalent to choosing option 4 in the main menu (Debug), then choosing option 1 in the debug menu (Trace), then choosing option 1 in the trace menu (Driver Trace). In addition to menus, some screens have questions with letter choices. In the line below, several elements may be identified:

lmi-type((A)NSI, (G)roup of four, (N)one )[ANSI]:

• Parameter description – The name of the parameter to be configured, in this case “lmi-type”.

• Options – Legal choices. The letter in parentheses is the letter that selects the corresponding option.

• Current value – The option in square brackets is the current value.

Pressing <Enter> without typing a new value leaves the item unchanged.

Chapter 3 - Using CyROS Menus 15

Cyclades-PR2000

Special Keys

<Enter> or <Ctrl+M> These keys are used to end the input of a value. <ESC> or <Ctrl+I> These keys are used to cancel a selection or return to the previous menu. In

some isolated cases, this key jumps to the next menu in a series of menus at the

same level. <Backspace> or <Ctrl+H>These keys have the expected effect of erasing previously typed characters. L When available, this option displays the current configuration. For example, in

the Ethernet Interface Menu, “L” displays the Ethernet configuration. <Ctrl+L

This key combination displays the same information as the L option, above, but

works like a toggle switch to allow display of one page of information at a time or

display the entire configuration without page breaks. <Ctrl+C

This key combination disables any traces activated in the Debug Menu.

On leaving a menu where a change in configuration was made, CyROS will ask whether or not the change is to be saved:

(D)iscard, save to (F)lash, or save to (R)un configuration:

Selecting

Discard

will undo all changes made since the last time the question was asked. Saving to

Flash

memory makes all changes permanent. The changes are immediately effective and are saved to the configuration vector in flash memory. In this case, the configuration is maintained even after a router reboot.

Run

Saving only to the

configuration makes all changes effective immediately, but nothing is saved permanently until explicitly saved to flash (which can be done with the option ADMIN =>WRITE CONFIGURATION=>TO FLASH).

The menus and parameter lists are represented in this manual by tables. The first column contains the menu item or the parameter, and the second column contains its description.

This menu interface is also available via Telnet if one of the interfaces has been connected and configured. The menu interface is the same as that described earlier in this section. Using Telnet instead of a console for the initial Ethernet configuration is discussed in Appendix C of the Installation Manual.

After one of the interfaces has been connected and configured, there is another way to interact with CyROS. Type the IP address in the location field in an HTML browser of a PC connected locally or remotely through the configured interface. A super-user ID and password will be requested (these are the same ID and password used with the line-terminal interface). A clickable image of the router back panel will apear, as shown in Figure

CHAPTER 4 STEP-BY-STEP INSTRUCTIONS FOR COMMON APPLICATIONS

This chapter provides detailed examples that can be used as models for similar applications. Turn to the example that is closest to your application, read the explanations, and fill in the blank spaces with parameters appropriate to your system. At the end of the section, you should have listed all the parameters needed to configure the router. At that point, read chapter 3 if you have not already, and configure your router with help from later chapters of the Installation Manual, when needed.

Example 1 Connection to an Internet Access Provider via Modem

This section will guide you through a complete router installation for the connection of a LAN to an Internet access provider via PPP. The configuration of NAT (Network Address Translation) will also be shown. Figure

4.1 shows the example system used in this section. Spaces have been provided next to the parameters needed for the configuration where you can fill in the parameters for your system. Do this now before continuing.

FIGURE 4.5 PPP ENCAPSULATION MENU PARAMETERS

23Chapter 4 - Step-by-Step Instructions

Cyclades-PR2000

STEP FIVE A static route must be added to tell the router that all traffic not intended for the local LAN should be sent to the Access Provider. Chapter 9 of the Installation Manual explains static routes and other routing methods available in CyROS. Fill in the spaces in Figure 4.6 with the values for your application.

CONFIG=>STATIC ROUTES=>IP=>ADD ROUTE

Menu Parameter Example Your Application

No Static Route

FIGURE 4.6 STATIC ROUTE MENU PARAMETERS

STEP SIX NAT must now be activated. There are two varieties of NAT: Normal and Expanded. This example uses the Normal NAT Mode. The other mode is explained in the chapter on NAT in the Installation Manual.

Menu CONFIG =>SECURITY =>NAT =>GENERAL

Parameter Example Your Application

Nat Status Enabled Nat Mode Normal Disable Port Translation No

FIGURE 4.7 NAT GENERAL PARAMETERS

24Chapter 4 - Step-by-Step Instructions

Cyclades-PR2000

STEP SEVEN NAT parameters will now be determined for routing outside of the local LAN. Network Address Translation maps the local IP addresses, registered in the local address range menu below, to the one global IP address assigned by the access provider. Local IP addresses not indicated in this menu will be discarded.

Menu CONFIG =>SECURITY =>NAT =>LOCAL ADDRESS =>ADD RANGE

Parameter Example Your Application

First IP Address 192.168.0.10 Last IP Address 192.168.0.30

FIGURE 4.8 NAT LOCAL ADDRESS RANGE MENU PARAMETERS

The factory preset values for all other NAT parameters are appropriate for this example. STEP EIGHT

Now that the parameters have been defined, enter into each menu described above, in the order presented (read chapter 3, Using Menus, if you have not done so already). Set the parameters in each menu according to the values you wrote in the figures above. Save the configuration to flash memory at each step when requested — configurations saved in run memory are erased when the router is turned off. If you saved part of the configuration to run memory for some reason, save to flash memory now using the menu option ADMIN =>WRITE CONFIGURATION =>TO FLASH.

STEP NINE The Ethernet interface can be tested as described in the troubleshooting appendix. The SWAN interface can be tested in a similar manner. At this point, you should create a backup of the configuration file (in binary) and print out a listing of the configuration.

25Chapter 4 - Step-by-Step Instructions

Cyclades-PR2000

Instructions for creating a backup of the configuration file.

Use the menu option ADMIN =>WRITE CONFIGURATION =>TO FTP SERVER. Fill in the IP address of the computer where the configuration file should be saved, the file name, the directory name, and the user account information. This configuration file can later be downloaded with the ADMIN =>LOAD CONFIGURATION =>FTP SERVER option.

Instructions for listing the configuration.

The menu option INFO =>SHOW CONFIGURATION =>ALL will list to the terminal screen the configuration of the router. This can be saved in a text file and/or printed on a printer.

STEP ONE The first step is to determine the parameters needed to configure the Ethernet interface (ETH0). The parameters in the Network Protocol Menu (IP) are shown in Figure 4.10. Fill in the blanks for your application in the right-most column. These parameters will be entered into the router later, after all parameters have been chosen. Each parameter in this menu is explained in more detail in chapter 5 of the Installation Manual.

Menu Parameter Example Your Application

Active or Inactive Active enables IP communication (IPX and

Transparent Bridge are not used in this

example). Interface Unnumbered Numbered Primary IP Address 100.130.130 .1 Subnet Mask 255.255.255.0 Secondary IP Address 0.0.0.0 for none. IP MTU Use the preset value, 1500. This determines

whether or not a given IP datagram is

fragmented. NAT Global, because NAT is not being used in this

example. ICMP Port Inactive Incoming Rule List None, filters are not included in this example. Outgoing Rule List Name None, filters are not included in this example. Proxy ARP Inactive IP Bridge Inactive

STEP TWO No more parameters are necessary for the Ethernet interface. The other interface to be configured is the SWAN in slot 1. The SWAN physical media parameters are shown in Figure 4.11. Fill in the values for your application. The SWAN configuration is described in more detail in chapter 6 of the Installation Manual.

Mode Synchronous. Clock Source When the interface is connected to a

DSU/CSU, the

External

Media for SWAN Cable V.35 in the example because the DSU/CSU

is V.35. The type of cable is detected by the

router, so if the correct cable is connected to

the DSU/CSU the router will choose this

value as the default.

Menu Parameter Example Your Application

Active or Inactive Active enables IP communication (IPX and

Transparent Bridge are not used in this

example). Interface Unnumbered/

Numbered Numbered Primary IP Address 200.240.230 .2 Subnet Mask 255.255.255.240 is the mask in the

example. Secondary IP Address 0.0.0.0 for none. IP MTU Use the preset value, 1500. This

determines whether or not a given IP

datagram is fragmented. NAT Global, because NAT is not being used in

this example. ICMP Port Inactive Incoming Rule List None, filters are not included in this

example. Outgoing Rule List Name None, filters are not included in this
