Troubleshooting Your PathBuilder S21x Switch

Introduction

This appendix describes some of the actions you can take to correct problems you may be having with your PathBuilder S21x switch.

Tro ubleshooting Your PathBuilder S21x Switch C-1

While Setting Up Y our Configuration

While S ett ing Up Your Configurat io n

Introduction

This section describes the ways you can use to isolate problems that you may encounter while setting up a PathBuilder S21x switch to pass IP traffic over PPP links. For discussion purposes, the following network configuration (shown in Figure C-1) is assumed.

Note

The configuration of the local PathBuilder S21x switch and the number to call can be obtained by defaulting the node—selecting “Default Node” from the CTP’s Main menu.

Figure C-1. Network Configuration

Note

The IP addresses use d in this configuration example are for illustration purposes only. You must obtain registered IP addresses fr om your netw ork administrator or your Internet Servic e provider, and configure them in your PathBuilder S21x switch before connect ing to the Internet or Intranet.

Checking the Physical

Use these procedures to check your PathBuilder S200 series switch connection and interface:

Connection

Step Action

Ensure that the STS LED is ON to confirm that power is connected and that the uni t is working. ( Other LEDs may be ON or blink occasionally.)

If the STS LED flashe s continuously for more than 30 seconds a fter the power is applied, the software image in the flash is corrupted and the node is waiting for software to be coldloaded. Refer to the Software

Installation and Coldloading Manual

for more infromation on cold-

loading software.

If you are connected to the control port using an async terminal, (9600 bps, 8 bits, no parity), type “AT <CR>” and confirm that the PathBuilder S200 series switch outpu ts “OK.” Then log into the CTP.

C-2 Troubleshooting Your PathBuilder S21x Sw itch

While Setting Up Your Configuration

Pinging the Local LAN Interface

From the workstation or PC connect ed to the same loca l LAN segment that the PathBuilder S21x switch is connected to, ping the LAN interface of the PathBuilder S200 series swi tch (“ping 10. 10.10.1”) . The LAN LED should f lash whe ne v er a Ping packet is received.

If the LAN LED does not flash, check the configur ation of the PC and the LAN connection and do the following:

Step Action

Check the IP address and IP address mask of your PC or workstation, making sure that they are set to valid address and mask appropriate for your local subnetwork. (In the above example, the IP address of the PC must be set betwee n 10.10. 10.2 an d 10.10.1 0.254 ) and the address mask must be set to 255.255.255.0).

Check the statistics of the LAN port (port 5) of the local node , making sure that the “Carrier” says “Present”. If the “Carrier” fie ld displays “Lost”, there is a problem with your LAN connection and you should do the following:

• If you are using a BNC connection between your workstat ion/P C and the PathBuilder S21x switch, make sure that you put in the 50

Ω

termination resistors at both ends of the line.

• If you are connecting your LAN using the 10BaseT and a 10BaseT Hub, check the display at the Hub to ensure that the connec tion between PathBuilder S21x switch and the Hub is correct. (Most Hubs have LEDs that stay ON when the carrier is detected).

• Change the RJ45 twisted pair cable between PathBuilder S200 series switch and your Hub as it may be damaged. A straightthrough 10BaseT cable is generally required between PathBuild er S21x switch and a 10BaseT Hub.

If there is only a sin gle PC or work station connecting to the PathBu ilder S200 series switch, and you are not using a 10BaseT Hub, ensure that you have used the RJ45 crosso ver cable, shipped with your PathBui lder S21x switch, to connect between the PC and the Path Builder S200 series switch.

If the LAN LED does flash, but there is no ping respo nse, do the following:

Step Action

From the CTP, check the stati stics of the LAN port ( Port 5) (se lect menu option Statistics, and select port 5) while sending ping packets.

Confirm that the Rx Frame Count, in the Data Summary, increases as the ping packet arrives.

Check the Tx Frame Count field in the Data Summary part of the LAN port statisti cs. If the field increases for every ping packet it receives, t he LAN and the configuration should be working.

Tro ubleshooting Your PathBuilder S21x Switch C-3

While Setting Up Y our Configuration

Step Action

If the RX Frame count increases, but the Tx Frame Count does not, the problem is most likely due to misconfiguration in t he IP router I nterf ace #1. Make sure that the IP addresses and IP address mask (select menu option Router -> IP Interfaces -> Interface 1) are set proper ly.

Pinging the Local WAN Interface

Once you are successful in getting ping responses from the local LAN i nterface, you can proceed to ping the local WAN interface (“ping 10.10.20.1” in the example). If there is no response, then check the following:

Step Action

Confirm that the IP interfaces (either 5 or 6) of the WAN link that you are trying to ping are configured for Enable. (Select menu item Router->Con figu re Inter face St at es. )

Confirm that th e IP add res s and IP ad d re ss ma sk o f the WAN interface you are pinging are confi gur ed properly.
