you have a 3550-12T, so I am assuming that ports 0/11 and 0/12 are the gbic ports. if you check the documentation, you will find that speed cannot be set in a gbic port.
http://www.cisco.com/univercd/cc/td/doc/product/lan/c3550/12112cea/3550cr/cl i2.htm#xtocid101 "You can configure Fast Ethernet port speed to either 10 or 100 Mbps. You can configure Gigabit Ethernet port speed to 10, 100, or 1000 Mbps. You cannot configure speed on Gigabit Interface Converter (GBIC) interfaces, but for 1000BASE-SX, -LX, or -ZX GBICs, you can configure speed to not negotiate (nonegotiate) if connected to a device that does not support autonegotiation."
