Chapter 7: General Configuration Using Local Management

Selecting the Frame Type for a Port

On each port, frame type specifies the format of the frame in which IP packets are encapsulated for transmission. The frame type options available for each router port are dependent on the type of media supported by that router port.

To select the frame type for a port, complete the following steps:

1.Use the arrow keys to highlight the Framing field.

2.Use the ENTER key to toggle the entry to the correct frame type for the port.

3.Use the arrow keys to highlight the SAVE command at the bottom of the screen and then press ENTER. The message “SAVED OK” displays.

Setting the Maximum Transmission Unit (MTU)

The Maximum Transmission Unit specifies the maximum packet size for all IP packets that are transmitted.

To select the MTU for a port, complete the following steps:

1.Use the arrow keys to highlight the MTU field under Port Level Setup.

2.ENTER an MTU value for the media used.

3.Use the arrow keys to highlight the SAVE command at the bottom of the screen, then press ENTER. The message “SAVED OK” displays.

Enabling IP Routing Services on a Port

The ability to switch IP Routing Services on and off on a port-by-port basis provides great flexibility. On the same device, some ports can be routing IP traffic while other ports are bridging it. As you are in transition from a bridged network to a routed network, this flexibility allows you to implement IP routing and test your routing configuration on a port-by-port basis.

If necessary, you can temporarily disable the IP routing on any port without losing your configuration, or you can temporarily switch from IP routing back to bridging.

To enable IP Routing Services on a router port, complete the following steps:

1.Use the arrow keys to highlight the IP Routing field under Port Level Setup.

2.Use the ENTER key to toggle the field to ENABLED.

3.Use the arrow keys to highlight the SAVE command at the bottom of the screen, and then press ENTER. The message “SAVED OK” displays.
