You see the interface configuration in the Information pane. Click the General tab. Click Mode Admin. Set the desired interface mode from the Admin drop-down menu. Optionally, set other configuration parameters using the other tabs. Click Apply Changes icon. Configuring Administrative Speeds By default, the administrative speed for an interface is automatically calculated by the switch. Caution Changing the administrative speed is a disruptive operation. To configure administrative speed of the interface using Fabric Manager, follow these steps: Step 1 Step 2 Step 3 Step 4 Expand Switches > Interfaces then select FC Physical. You see the interface configuration in the Information pane. Click the General tab. Click Speed Admin. Set the desired speed from the drop-down menu. The number indicates the speed in megabits per second (Mbps). You can set the speed to 1-Gbps, 2-Gbps, 4-Gbps, or auto (default). Click Apply Changes. For internal ports on the Cisco Fabric Switch for HP c_Class BladeSystem and Cisco Fabric Switch for IBM BladeCenter a port speed of 1 Gbps is not supported. Auto-negotiation is supported between 2 Gbps and 4 Gbps only. Also, if the BladeCenter is a "T" chassis, then port speeds are fixed at 2 Gbps and auto-negotiation is not enabled. 20-12 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
