Please explain the benefit of running a group of Catalyst switches together via Gigastack in the setup that drops all communication to half-duplex. Doesn't this slow down overall communications and defeat the purpose??
Well I have recently discovered that our network is utilizing about 21 Catalyst switches all running in this half-duplex configuration. The network has probably a few hundred users on it. How big of a performance hit is this compared to if all switches ran the individual full duplex connection to its own GBIC port on a higher end catalyst? I need to give a convincing argument if it warrants a recommendation to management to spend the money.
I also heard that the half duplex solution would not be supported by Cisco if VoIP was being utilized. We are going to implement this technology in the future, so if this is true, it would help my argument that its worth the money to switch to a full duplex configuration. Can anyone confirm whether Cisco won't support the half duplex with VoIP??
