Descriptions of Fixed Problems

25Added 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.

Fixed a problem with console lockup that can occur after you enter a Ctrl+C command at the Administration Console.

27Fixed performance problems (slow responses, lost connections, and so on) that occurred when the system accessed the ARP table via SNMP.

Fixed a memory leak that was caused by ARP frames. Fixed an ARP-related problem that resulted in buffer loss.

28Added support for LEC IDs of zero.

30Fixed the cause of various cp panic messages when the system is interoperating in an ATM environment.

31Fixed a buffer leak that was caused by receiving packets that were larger than legal Ethernet sizes.

32Changed how passwords are handled in the system.

Changed the system response for certain MIB requests. When the MIB objects swSysSystemConsoleWritePwd and swSysSystemConsoleAdminPwd are requested by a management entity, the system now returns the message NoSuchName, regardless of the access level of the community string that you use to request these objects.

33Fixed a problem with Rlogin so that customers can use Rlogin instead of Telnet. The use of Telnet causes small memory leaks of about 40 bytes per session. If you Telnet to a system with a Rev 7 motherboard every 15 minutes on a 7x24 basis, then it would take approximately 24 days to start receiving memPartAlloc error messages when you access the system for information. This time would be longer than 24 days for systems with Rev 8 motherboards and shorter for systems with Rev 6 motherboards, because they have different amounts of memory. A system reboot or power cycle returns all memory that is lost through the leaking process.

34Provided a software fix for a flash memory issue. In certain circumstances, if the system was rebooted, the system indicated unrecoverable checksum errors. This fix incorporates a new expander file to be used during the software installation process.
