Configuring Ethernet Speed and Duplex Settings
The Cisco 1941-W ISR interface supports only 1000 Mbps speed and duplex settings by default, and the
interface is always up. When the wireless device receives inline power from a switch, any change in the
speed or duplex settings that resets the Ethernet link reboots the wireless device.
Note The speed and duplex settings on the wireless device Ethernet port must match the Ethernet
settings on the port to which the wireless device is connected. If you change the settings on the
port to which the wireless device is connected, change the settings on the wireless device
Ethernet port to match.
The Ethernet speed and duplex are set to auto by default. To configure Ethernet speed and duplex, follow
these steps, beginning in privileged EXEC mode.
