    SmartSwitch 6C110 chassis with other Cabletron networking devices. For example, the slots of the 6C110 chassis can be populated by a mix of SmartSwitch 6500 modules and SmartSwitch 6000 Ethernet switches. Both the CSM and TSM are hot swappable. This means that you can install and remove TSMs and CSMs from the 6C110 chassis without turning of chassis power.

  • Page 18: Smartswitch 6500 Modules

    For redundancy, the SmartSwitch 6500 supports up to two CSMs in a single 6C110 chassis. When one CSM is active, the other CSM is in standby mode. If the active CSM fails, the standby CSM can be made to assumes the active role.

The SmartSwitch 6500 uses local clients to connect itself to the VLANs that it supports. This is analogous to a phone company that supports a communication system. Even though the phone company maintains the circuits, a call to the phone company itself cannot be made unless the phone company has its own number and connection on its own phone system.

    Multi-level PNNI Topology Connectivity is now established between the two peer groups. For example, if LANE services are running on a switch within peer group A, LANE clients can exist in group B. The clients in group B will traverse the link between the two groups, find the LANE server in group A, and join the ELAN.

    7.1.4 EFCI, EPD, and RM Cell Marking To control switch congestion, the SmartSwitch 6500 implements standard resource management cell (RM-cell) marking, explicit forward congestion indicator cell marking (with backward RM cell marking), and early packet discard (EPD). These congestion control schemes are triggered when the number of cells within shared memory reaches user-definable thresholds.

    Accessing the Boot Load Prompt Boot load commands are executed from the boot load prompt. The boot load prompt is not part of the switch console, and is accessible only after a reboot and before the switch firmware is loaded. Consequently, the boot load commands can be used only through a terminal connection.

Make sure that the TFTP/Bootp server can be reached by the SmartSwitch 6500 Ethernet interface. Connect a dumb terminal (or workstation running terminal emulation software) to the SmartSwitch 6500 Terminal port.

  • Page 112: Events And Alarms

    EVENTS AND ALARMS The SmartSwitch 6500 switch records and reports its operation in real-time through the use of events and alarms. An event is an occurrence of a significant activity. For instance, a port going down or a client joining an ELAN are examples of events.

  • Page 113: Viewing Events And Alarms

    Both events and alarms are stored in shared RAM. However, the 40 most recent alarms are also stored in flash RAM. Storing these 40 alarms in flash RAM makes them persistent between reboots of the SmartSwitch 6500, and provides information about the state of the switch prior to reboot. Note Alarms are collected and stored in flash RAM in groups of four.

    Events and Alarms Depending on the activity of your SmartSwitch 6500, the appearance of events on Note the SmartSwitch 6500 may be too frequent to use the SmartSwitch 6500 console comfortably. It is recommended that you turn on the automatic display of events only when troubleshooting.

  • Page 115: Saving Core Dumps

    SAVING CORE DUMPS The SmartSwitch 6500 core dump feature allows you to specify a local Ethernet host where, in the event of a system failure, the SmartSwitch 6500 sends a copy of its memory. SmartSwitch 6500 system memory is saved to two files, one containing CPU memory (core_cpu), the other common memory (core_cmn).
  • Page 116 Saving Core Dumps If a system failure occurs while the core dump feature is enabled, the SmartSwitch 6500 console appears similar to the example below. The SmartSwitch 6500 then begins sending images of its memory to the core dump files on the TFTP server.
