We're having trouble with spurious MCI resets with version 1.7 of the MCI microcode. The resets seem to occur when traffic on the interfaces is heavy. The resets show up in "show controller mci" as: MCI 1, controller type 1.0, microcode version 1.7 128 Kbytes of main memory, 4 Kbytes cache memory, 22 system TX buffers Restarts: 1 line down, 0 hung output, 0 controller error ^^^ We are seeing this on two boxes, one with a CSC-2 and one with a CSC-3 processor. On the CSC-2 box, we tried swapping MCI boards, and booting both 8.1(19) and 8.1(25). On the CSC-3 box, we tried swapping MCI boards (only under 8.1(19)). This problem began when we moved to microcode 1.7 and seems to have stopped now that we've gone back to microcode 1.5. (We had been upgrading our MCI cards to 1.7 to solve the dribble-bit Ethernet incompatabilities and to improve the usefulness of the error counters. That's on hold until this is resolved.) Anyone know what's going on here? Thanks, Dan

We are seeing the same here. Our cisco routers are attached to FiberCom WhisperLans, and we do not see the problem with the 1.5 microcode. Any thoughts would be greatly appreciated. /mde/

Same here..... we upgraded to the 1.7 microcode and have since experienced the same problems.... We have a 1.5 microcde mci card comming today. I expect that will fix the problem. Anyone know if Cisco is working on this? We really would not like to replace 30 mci cards AGAIN. -- Jim Ray Harris Semiconductor Internet: jdr@semi.harris.com PO Box 883 MS 62B-022 Phone: (407) 729-5059 Melbourne, FL 32901

Well, the 1.5 microcode did the trick. Don't know why. -- Jim Ray Harris Semiconductor Internet: jdr@semi.harris.com PO Box 883 MS 62B-022 Phone: (407) 729-5059 Melbourne, FL 32901

Have you tried version 3? htam norman - hewlett packard. norm@hpctn9.corp.hp.com
