    ETHERNET EXTENDERS—CONFIGURATION GUIDE 1. Introduction Ethernet Extenders can be used for various bridging and routing functions, and can connect an Ethernet or Token Ring LAN to the Internet or Intranet via ISDN, Frame Relay, asynchronous or synchronous dialup, or Digital Data Service (DDS) links operating at data rates up to 1.5 Mbps. This manual gives a general introduction to the Ethernet Extender and describes how to configure it.

Using filters here will forward or block traffic from the LAN outwards. • From Link to the LAN. Using filters here will forward or block traffic from the link inwards. Using a variety of parameters, Advanced Filters can be used to regulate different protocols, to totally or partially block traffic, and to control traffic between links.
  • Page 69 ETHERNET EXTENDERS—CONFIGURATION GUIDE Multiple Filters Up to 18 filters can be defined. If there are 2 filters which have contradictory operations, forwarding takes precedence over blocking. Example: You want to allow only one particular user on the small-office LAN to access the Internet for FTP purposes. To ensure that no one else is able to access the Internet, create a blocking filter for all traffic going to the link.

    ETHERNET EXTENDERS—CONFIGURATION GUIDE A.3 Provisioning ISDN The Ethernet Extender passed the interoperability and ISDN Ordering Codes (IOC) tests at Bellcore with all three North American switches (AT&T, Northern Telecom, and Siemens). The IOC program is designed to simplify ordering an ISDN line for National ISDN. The Ethernet Extender is registered at Bellcore under packages R and EZ1.
  • Page 94 APPENDIX A: Important ISDN Issues An inconsistency exists between the ISDN protocols used on different types of switches. National ISDN-1 standard does not allow access to both B channels with only one SPID. If you use National ISDN-1 or AT&T Multipoint protocols on a 5ESS switch, it is possible that you will receive only 1 SPID for both B channels.

    ETHERNET EXTENDERS—CONFIGURATION GUIDE Appendix B: BOOT Manager B.1 Preface The Ethernet Extender includes a Dual Image Flash, capable of storing two different versions of software in two different partitions. Upon reset, the Ethernet Extender automatically runs the program stored in the primary (active) partition. New software versions are loaded into the secondary (backup) partition.

  • Page 97: Load New Software

    ETHERNET EXTENDERS—CONFIGURATION GUIDE B.3.1 L OFTWARE Select this option to download new software via the control port using the XMODEM protocol. During the process, the new program code is downloaded to the FLASH secondary partition, thus erasing its previous contents. Upon completion, the newly downloaded FLASH partition becomes the primary partition, while the old version’s partition becomes the secondary partition.

    APPENDIX B: BOOT Manager B.3.4 R EACTIVATE ECOND ARTITION Select this option to turn the secondary partition into the primary partition (and vice versa). In this way you can return to the previous software version permanently. This command may be executed up to 16 times, after which downloading of the new software will be required. Therefore avoid using this option for a one-time run of the old version (use the Run Second Partition option for that purpose).

  • Page 99: Exit

    ETHERNET EXTENDERS—CONFIGURATION GUIDE Change your terminal baud rate and press Enter 2 or 3 times to ensure that the device identifies the new value. NOTE The terminal emulator of Windows 95—HyperTerminal—has a bug: After changing baud rate the status line presents the new value, but this value will not come into effect unless you perform the disconnect and connect commands immediately after performing the change.
