Cat 6 crossover only getting 100 Mbps?
Mark sure that the computers are both set to 1000 instead of auto. Try using a network switch which has Gig ports on it and see if that helps any. Also make sure that DMA is turned on on both side of the communication. DMA is Direct Memory Access, a protocol used by disk drives [...]

When do I use RIP, EIGRP, IGRP AND OSPF?
The choice of protocol is totally dependent on the policy/architecture of a company. If you have a small network you can use RIP which has a limitation of 16 hops. For slightly larger networks, you can use IGRP which support 256 hops. EIGRP is Cisco’s proprietary routing protocol and can expand across very large networks. [...]

How do I configure network ports to full-duplex on McData switches?
Unfortunately, I haven’t worked on this specific equipment. I’m sure your manual can help explain the steps you need to take. The most likely issue is a speed/duplex mismatch with the switchport or device it’s attached to. Make sure that the device it’s attached to is not set to 100/full, but instead to auto/auto. Thanks!

CSMA/CA
Hello, There are no real alternatives to CSMA/CA. CSMA/CA is used primarily for wireless networks (WLANs and PANs) and doesn’t much apply to physical networks. If you’re using a physical network, CSMA/CD may be more useful for you. Thanks! Ryan
