For a LAN party though, throughput shouldn't really matter that much.... you're using a Cisco switch which is MUCH better than any LAN party I've seen. The last one I went to had several hundred computers connected on Dlink crap.... that didn't work so good..;)
When you figure 100-150Kbps on some games I have played, it's more about latency and consistency which with a class 6148 I can't see a reason for any problems...

Just to clarify that, the 6148A is the newer/better version of the 6148, not just the GE version. The term after the number tells the speed: WS-X6148A-GE-TX - new 10/100/1000 WS-X6148A-RJ-45 - new 10/100 WS-X6148-RJ45 - old 10/100 The 6148 vs 6348 vs 6548 vs 6748 distinction is more about the forwarding technology (classic bus, CEF256, CEF720) However, both 6148 and 6348 are classic bus with no fabric, and I'm having trouble finding the distinction between them. According to Cisco: http://www.cisco.com/en/US/products/hw/switches/ps700/products_configuration _example09186a0080118a5c.shtml "Each WS-X6348 card is controlled by a single Application-Specific Integrated Circuit (ASIC) that connects the module to both the 32 GB data bus backplane of the switch and to a set of four other ASICs which controls groups of 12 10/100 ports." I can't find a similar document on the 6148, but I wouldn't expect it to perform better (6148A however is much better but also newer and thus probably more expensive "on the bay") There's limitations on the ASICs, the backplane bus, and the Supervisor, but I wouldn't expect them to be a problem for a LAN-party. Just as he mentioned, don't expect to drive a full 100 Mbps to each port all the time. -Geoff On Tue, Dec 23, 2008 at 10:45 AM, Pete Templin <[email protected]> wrote: > [email protected] wrote: > >> Can anyone explain the difference between the cards ws-x6148 and >> ws-x6348?
