    2500 Intelligent Switching software, version 8.1.1, dated December 20, 1996. In mid-1997, 3Com changed the name of the LANplex 2500 switch to the CoreBuilder 2500 switch. In version 8.1.2, however, the LANplex name and related abbreviations, such as lp and lpx, remain in the filenames and displays on the Administration Console.
  • Page 8: About Software Version

    2500 I 8.1.2 UILDER NTELLIGENT WITCHING OFTWARE ERSION About Software Intelligent Switching software version 8.1.2 is a maintenance release that Version 8.1.2 includes several patches (bug fixes). Table 1 lists the patch numbers and descriptions. Table 1 Patch Descriptions Patch Descriptions of Fixed Problems Added the ability to save nonvolatile configuration data from one system and restore it to another system.
  • Page 9 About Software Version 8.1.2 Table 1 Patch Descriptions (continued) Patch Descriptions of Fixed Problems Added functionality to disable ATM throttling to the Broadcast and Unknown Server (BUS). A value indicates the number of unknown addresses that can be sent to the BUS. A new value of "0" disables this function.
  • Page 10: System Issues

    The following system issues have been identified for software version 8.1.2: When a ping is initiated from the CoreBuilder 2500 system and is destined to an ATM device that has a specific ATM adapter card, multiple pings are required before communication is initiated. This situation arises because of the amount of time required for the adapter card to resolve ATM ARP.
