Hi, Yes I have been through this before. I remember older best practise documents stating to use Desirable/Desirable etc, and I have put in networks using this. However I have done some testing in the lab and hard-coding trunks & channels does improve convergence time slightly. I also think it is good administrative practise to ensure all ports are configured specifically for their purpose and unused ports are shutdown and placed into a 'null' VLAN.
This all obviously goes wrong if someone decides to do some re-cabling but it would do either way anyway :o)
For testing in the lab we used just two switches at Layer-2 and used HrPing utility on a PC. This was to verify the layer-2 link had come up and converged. Obviously in a structured network there are more elements to be considered like STP & routing protocols but for pure link up times it did improve with hard-coding things (trunks & channels).
I understand the potential issues that would arise if one end was accidentally reconfigured or a cable was re-patched incorrectly. This is all part of the administrative procedures though.
I myself don't like hardcoding them as more than once we have seen where if you hardcode a trunk really all it needs to see is a physical connection and it can say it is trunking when it really is not , if you let them negotiate the trunks and etherchannels we have not seen this problem .
