Configuring Maximum Transmit Unit

Maximum Transmit Unit (MTU) is the size of the largest packet that can be sent
over the network. The standard MTU value for Ethernet networks is usually 1500
bytes and for PPPoE connections, it is 1492 bytes.
Unless a change is required by your ISP, Cisco recommends that you choose
Default in the MTU Type field. The default MTU size is 1500 bytes. If your ISP
requires a custom MTU setting, choose Custom and enter the MTU Size.

Configuring the Cisco RV220W MAC Address

The RV220W has a unique 48-bit local Ethernet hardware address. In most cases,
the RV220W's default MAC address is used to identify your Cisco RV220W to
your ISP. However, you can change this setting if required by your ISP.
In the MAC Address Source field, choose one of the following:
• Use Default Address (recommended).
• Use this computer's MAC—Choose this option to assign the MAC address
of the computer that you are using to configure the RV220W.
• Use This MAC—Choose this option if you want to manually enter a MAC
Address that is expected by your ISP.
If you chose not to use the default MAC address, in the MAC Address field, enter a
MAC address in the format of XX:XX:XX:XX:XX:XX, where X is a number from 0
through 9 or a letter from A through F.
