Managers - quick and accurate responses as always.
The problem with the late collisions was the half/full duplex capability of the
SunSwift card (or lack of it). I had the 28115 configured for Full duplex
which the SunSwift card cannot handle. Reconfiguring the hub to half duplex
cleared the problem and improved the network performance.

I am getting a lot of "late collision" messages on my Axil box.
The Axil is configured thus,
dual 81 superSPARCS
Solaris 2.5 - no patches
SunSwift 100baseT and Fast Wide SCSI SBus card
- 100 BaseT connected to 28115 SynOptics Hub
The error message is
May 1 14:22:30 leviathan unix: SUNW,hme0: late collision
These messages appear regularly but do not appear to adversely affect the
network performance. However the machine is not heavily loaded yet and it may
be a problem later.
The SunSwift adapter message as it is detected on bootup
SUNW,hme0: FEPS (Rev Id = 22) Found

SUNW,hme0 is /iommu@f,e0000000/sbus@f,e0001000/SUNW,hme@3,8c00000
SUNW,hme0: Using Internal Transceiver
SUNW,hme0: 100 Mbps Link Up
Anyone with any thoughts on whether this is a potential problem?
