Descriptions of Fixed Problems

 

 

 

 

5

Added the ability to save nonvolatile configuration data from one system

 

 

and restore it to another system.

 

 

Fixed a problem with the nvdata save process and .nvd file extensions.

 

 

 

 

6

Fixed a buffer leak problem with IPX NetBIOS in configurations that have

 

 

no outgoing interfaces.

 

 

Fixed a problem in which IPX NetBIOS network numbers were corrupted

 

 

when using FDDI 802.2 encapsulation on an IPX interface. This problem

 

 

affected the processing of an IPX NetBIOS frame and potentially caused it

 

 

to be dropped.

 

 

 

 

10

Fixed a problem with Fast Ethernet port lockups.

 

 

 

 

13

Fixed the FDDI Source Route frame problem with Panic 3 errors. Errors

 

 

were caused by frames with unicast DA, known DA, source route SA,

 

 

known SA, and frames in error.

 

 

Fixed a problem with multibuffer FDDI and ATM Panic 3 errors.

 

 

Fixed an error with the max VLAN condition that occurred while adding

 

 

VLANs.

 

 

 

 

15

Fixed the corruption problem with frames that required fragmentation

 

 

between FDDI and Ethernet.

 

 

 

 

17

Fixed filtering problems with ATM LECs.

 

 

 

 

18

Fixed a problem in which, if an IP VLAN was removed, then the remaining

 

 

IP VLANs could no longer communicate with each other through the

 

 

system.

 

 

 

 

19

Fixed a problem in which AUI and BNC ports hung when a certain amount

 

 

of collision activity occurred.

 

 

 

 

22

Revised the fix that dealt with frame corruption during FDDI-to-Fast

 

 

Ethernet or FDDI-to-Ethernet fragmentation.

 

 

Fixed a problem with the initialization and timing of ATM LECs.

 

 

 

 

23

Fixed a problem that occurred if an ATM multicast limit was set. If that limit

 

 

value was reached on an ATM interface, all future traffic through that

 

 

interface was dropped.

 

 

 

 

24

Fixed the Panic78 frame buffer overreturn problem that was caused by

 

 

Source Route frames in error. This fix is only for Transparent Bridge Mode.
