Basic interface settings

All the mbox hardware comes with Gigabit Ethernet interfaces and each interface by default is in routing/Layer-3 mode. The logical interfaces are configured for specific purposes and they require specific settings, which are illustrated in other sections.

Below is a list of common settings available for all interfaces:

    • enable or disable
    • ip address setting (mbox support multiple IP addresses per physical or logical interface, for both IPv4 and IPv6 addresses).
    • MAC address setting. It is possible to change the default MAC address of each interface. Only do this for a specific reason that you’re fully aware of.
    • MTU size
    • duplex and speed (physical interface only)


    • access to mbox through console or CLI
    • identify the interface that you wish to configure
    • enter into interface configuration mode and change specific settings
    • please add "ip default-gateway x.x.x.x" if you're not using DHCP to get WAN IP.
