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 12

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 13

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.
Saving only to the

Run

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.

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

Paramet e r Example Your Appl ic ation

Last IP Address 192 .16 8.0 .3 0

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.

23Chapter 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.

Example 3 Link Backup

This example shows the configuration of a backup link, with a swan connection to a public Frame Relay
Network providing the primary link and a SWAN with a PPP connection providing the secondary link. Figure

4.16 shows the networks used in this example. It is assumed that the routers are already connected to LANs
and that the SWAN interfaces have already been configured and are working. The use of a SWAN to connect
to a Frame Relay network is described in example 2 and a connection using PPP is shown in example 1.

Please read the entire example and follow the instructions before turning the router on. The router is
programmed to log the super user off after 10 minutes of inactivity. All data not explicitly saved to
memory is then lost. Collecting the data

while

configuring the router will likely cause delays and

frustration.

STEP ONE
The bandwidth used by CyROS for multilink circuit calculations is that given in the traffic control menu, rather
than the actual physical bandwidth available. If this bandwidth value is not set, the preset value (zero) will be
used and the multilink circuit will not function. The bandwidth for both links (SWAN 1 and SWAN 2 in the
example) should also have been set when the interface was configured. If not, the multilink circuit will not work.
Since the bandwidth was probably not set when the link was configured, you should make sure the value is the
desired one.

Now, the primary link (Slot 1) and the secondary link (Slot 3) must be registered as a multilink circuit. First, a
multilink circuit is created and assigned an identifier. This is done in the CONFIG =>MULTILINK menu. Then,
the two links are added to the multilink circuit. The parameters used in the example for the two interfaces in

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. Be sure to change the superuser password using the menu
option CONFIG =>SECURITY => USERS =>MODIFY. The user ID, super, can remain the same, but the
password must be changed to avoid unauthorized access.

37Chapter 4 - Step-by-Step Instructions

STEP SIX
The multilink circuit can be tested by temporarily deactivating the interface on the primary link. This is done in
the ADMIN=> START/STOP INTERFACE menu by selecting the SWAN interface. If there is traffic, the backup
link should then take over, and the menu item INFO =>SHOW ROUTING TABLE will show that the backup link
is working. (To create traffic, try pinging a host in the destination network.) At this point, you should create a
backup of the configuration file (in binary) and print out a listing of the configuration.

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

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.

Testing the Ethernet Interface

After configuring the Ethernet interface, return to the main menu using the <ESC> key as many times as is
necessary. Save the configuration to flash memory (the operating system will ask how to save the
configuration on the way back to the main menu). The simplest way to test the link is by using the ping
application. From the main menu, choose APPLICATIONS =>PING. Enter the IP number of a host on the
network for the

HOST

parameter and accept the preset values for the rest of the parameters. The output on

the screen should appear as shown below.

round-trip min/avg/max = 0.98/1.19/1.96 ms

Pinging the router from a host on the network should give similar results. If the test fails, confirm that the link
LED is lit and that the

IP Address

and

Subnet Mask

parameters in the Network Protocol menu are correct for
the network to which the router is attached. The command CONFIG =>INTERFACE =>ETHERNET =>L will
display the current values of the interface parameters.

Appendix A - Troubleshooting 41

Cyclades-PR2000

Testing the WAN Interfaces

The WAN interface can be tested using ping as described in the previous section. If the ping is not successful,
check the routing table to see if a route to the destination exists (INFO =>SHOW ROUTING TABLE). The
menu items INFO =>SHOW STATISTICS =>SWAN and INFO =>SHOW STATUS =>SWAN may also provide
useful information.

If the router does not seem to be working properly, and none of the above advice has located the problem, the
hardware interfaces should be tested. This will determine if the problem is hardware, software, or configuration
related.

This test will be between the two SWAN interfaces.

1 Connect the cable labeled “cross” between the two interfaces to be tested.
2 Choose DEBUG =>HARDWARE TESTS =>NEW RUN-IN from the menu. Test options for each interface

are shown. Choose

Yes

for the two SWAN RSV interfaces and No for all other tests. Let the test run for a

while. Pressing “G” will show the General Statistics Table (Figure A.3).

FIGURE A.3 GENERAL STATISTICS TABLE.

• The first three columns show which interfaces are being tested.

• The H column shows which board is master and which is slave.

• The LP column indicates how many test loops have been completed.

• The E%% column shows how many errors per 1000 packets have occurred.

Appendix A - Troubleshooting 42

Cyclades-PR2000

• The S column reveals the stage of the test at the time the table was created — D = data transfer, S =

synchronization.

• The next 4 columns indicate bytes and packets sent and received.

• The last three columns indicate the port with which the interface is communicating.

The test should be run until at least one test loop (LP = 1) has completed. More loops can be run if
errors appear, to determine if the errors repeat or are just an artifact of the test procedure. If there
is a hardware defect, the value in the E%% column will be large.

Below the General Statistics Table, the time in test and total errors are indicated. If an error occurs, typing “E”
will show an Error Table with information about the error. Typing “S” will show a Status Table, indicating the
profile being tested at the time “S” was pressed. This does not supply information that can be interpreted by a
user.
