Ethernet Media Configuration Overview
You can configure the CTP Ethernet media to autonegotiate and set the speed to either 100 or 10 Mbps. By default, autonegotiation is enabled and the speed is to 1000 Mbps. If you choose to disable autonegotiation, the system prompts you to configure the desired speed.
The Ethernet configurations on CTP must match the configuration of the connected router or switch. Mismatched configurations, such as setting the CTP system to autonegotiate and the router to full duplex, will result in a misconfiguration and dropped packets. You must disable Cisco Discovery Protocol on the Fast Ethernet port connected to the CTP system.
Table 1 lists the valid Ethernet media configuration settings that CTP Series supports.
