Analyzing the configuration of a catalyst-4500 for one of my clients (switch that has some problems), I have seen a large use of
the "flowcontrol" command in all modes (receive / send, on / off / desideres).
I never use it, but here it is used on nearly all Giga interfaces.
The question is: is it a good idea or are there any contraindications?
Thanks for any suggestion.

Its like a quick form of qos it tells the sender to slow down when the int is congested , whats the issue your running into on the switch ?
Flow control is a feature defined in the IEEE 802.3x specification, enabling a receiving device to signal congestion to a sending device, which allows for the sending device to temporarily halt transmission, alleviating congestion at the receiving device

Generally it's a bad to use because it blocks all traffic on the port unless your using Converged Enhanced Ethernet (or one of similar that support priority-based flow control).
