PLXX499 APAR = IR37920 V3500 Fddi Driver. (CSP2SFA0.MTX) Fddi Microcode. (CSP2SFA0.ABS) PLXX499 replaces PLXX493, it is the same code, but was rebuilt in the library and adds the APAR number to the diskette. Includes PLXX450 (described below) Includes PLXX465B (described below) Includes PLXX490 (described below) Includes PLXX493 (described below) PLXX499 enhances the recovery capability for the fddi microcode if it should ever find itself in a receive-hang condition that was provided in PLXX493. If, at any time during the one second hang check loop, the FDDI microcode changes states the one second loop will reset the flag that says it is active. This will allow the 15 second loop to begin the Hang check process again to initiate the reset of the adater Mike Wyatt May 15, 1998 ----------------------------------------------------------------------- PLXX493 Provides recovery capability for the fddi microcode if it should ever find itself in a receive-hang condition. If the fddi driver finds that a lan frame has not been received in the last 15 second window, it will send a small frame out to itself. If that frame is not received, several more are sent out; and if none of those are received, a reset of the adapter will be done. The driver is built from the PVS library (tip), and the microcode is built from the official microcode libary, as F13_EDBG.BIN. Mike Young Mar 16, 1998 ----------------------------------------------------------------------- PLXX490 Corrects a problem when the 3172 fddi is attached dual-home, and the hub goes down, and the 3172 was staying stuck in isolated state, 1E19 is in the leds. Mike Young. 01.23.98 ----------------------------------------------------------------------- PLXX450 is a V3.500 patch - APAR = IR34434 March 10, 1997 The following task is re-applied. 1.Model 3 FDDI task (CSP2SFA0.MTX) When a 3172 FDDI adpater is configured for multiple TCP/IP connections recycling one TCP/IP host can bring down the others. ----------------------------------------------------------------------- ----------------------------------------------------------------------- PLX465B is a V3.500 patch - APAR = IR35379 The following task is re-applied. 1.Model 3 FDDI task (CSP2SFA0.MTX) When a 1E16 (Illegal Transmit Frame) is encountered, the 3172 previously logged the 1E16 and stayed operational. Now, the 1E16 causes the FDDI to go offline and intervention required. Mike Young Nov 18, 1997 -----------------------------------------------------------------------
