  • Page 91: A Redundant-Link Configuration Overview

    Appendix Redundant-Link Configuration Overview Introduction This appendix describes the configuration and implementation of the redundant-link pair (RLP) of links. Redundant-link configuration refers to two links that are configured on a single LAN to provide greater fault tolerance than a single port-to-port configuration provides.

  • Page 92: Major Components

    Major Components Major Components Redundant links consist of the following major components: • Master port pair • Responder ports • Nonresponder ports • Master control algorithm (MCA) • Primary link • Secondary link Basic Configuration The basic redundant-link configuration consists of a pair of master ports on the same module and two remote ports on one module or on separate modules.

  • Page 93: Redundant-Link Components

    Redundant-Link Components Redundant-Link Components Introduction This section describes the components that make up a redundant-link configuration. Redundant-Link Pair The redundant-link pair (RLP) is a pair of links that provide fault- tolerant communication in the event of transmitter, receiver, or cable failures.
  • Page 94 Redundant-Link Components The responder and nonresponder ports can reside on the same module as each other or on separate modules. Master Control Algorithm The master control algorithm (MCA) resides within the module that is assigned as the master and contains the master port pair. The MCA does the following tasks: •...

  • Page 95: Redundant-Link Operation

    Redundant-Link Operation Redundant-Link Operation How does it work? The MCA controls the redundant-link operation by: • Enabling the primary link at initialization time (assuming that there are no failures on that link). • Monitoring the primary link status for failures. •...

  • Page 96: Configurations

    Configurations Configurations Simple Redundant-link Configuration In its simplest form, a redundant link consists of a pair of master ports that reside on one module, and a pair of responder or nonresponder ports on a remote module. See Figure A-1. Figure A-1 Simple Redundant-Link Configuration Example Item Description Master port pair.

  • Page 97: Figure A-2 Complex Redundant-Link Configuration Example

    Configurations Complex Redundant-link Configuration A complex redundant-link configuration consists of a master port pair and responder ports, nonresponder ports, or a combination of the two. The responder or nonresponder ports reside on separate modules, as shown in Figure A-2. Figure A-2 Complex Redundant-Link Configuration Example Item Description Master port pair.

    Fault Detection Figure A-3 Partial Fault Detection Configuration Example Item Description Master port pair. Primary link (initially active). The master can detect a link failure here. Secondary link (initially standby and disabled). The master cannot detect a link failure here. Single nonresponder port (always enabled).

    Full Fault Detection The PORTswitch 900FP supports full fault detection. When the PORTswitch 900FP ports are connected to the ports of another repeater that supports this feature, such as a DECrepeater 90FS, failures are detected at either end of the receive or transmit link. See Figure A-4.

    RX Link Detects the failure Detects the failure Recommendations for Redundant-Link Configuration Consider the following recommendations when configuring the PORTswitch 900FP as redundant links: • Use responder ports (rather than nonresponder ports) whenever possible. • If you use a combination of responder ports and nonresponder ports, assign the responder ports to the primary link and the nonresponder ports to the secondary link.

    Calculated Loss Budget Table B-1 shows the calculated loss budget for 10BaseFL fiber-optic segments used to interconnect the PORTswitch 900FP with the cable plant. These measurements account for the connectors at either end of the segment. They are calculated using the transmit and receive optical power levels in decibels of optical power referenced to one milliwatt (dBm).

    FOIRL Compatibility FOIRL Compatibility Introduction This section discusses the IEEE 802.3 standard for fiber-optic interrepeater link (FOIRL) devices that specifies peak power levels. The standard specifies a -27.0 dBm minimum peak receive power = -30.0 dBm). This power level represents a 2.5 dB lower receive R(avg) sensitivity.

    When calculating the loss budget for fiber-optic devices, ensure that the higher output from the PORTswitch 900FP, in conjunction with the increased launch power into the two largest fiber sizes (85/125 and 100/140 microns), does not overload the receivers.

To make that determination, complete the...

    (MIB) groups based on the IETF draft standard MIB specified by RFC1757, where the primary purpose is to function within the PORTswitch 900FP, and not operate as an RMON probe. The RMON MIB groups include RMON Alarms and RMON Events.

  • Page 116: Alarms And Events Description

    RMON EventsGroup The RMON events group controls the generation and notification of events of the PORTswitch 900FP. Each entry in the eventTable describes parameters of the event that can be activated. Events are activated by alarms configured in the alarms group. You can specify, at your option, that a log entry is created for each eventEntry whenever the event occurs.
