Configuration overview
34 Administration for the Avaya G250 and Avaya G350 Media Gateways
Defining the USB-modem interface
If you intend to use a USB modem to connect to the G250/G350, you should also assign an IP
address to the USB-modem interface. It is not necessary to include a subnet mask.
1. Enter
interface usb-modem
to enter the
USB-modem
context.
2. Use the
ip address
command to define a new IP address for the USB-modem interface.
The following example assigns an IP address of 10.3.3.2 to the USB-modem interface:
Defining other interfaces
Your next step should be to define the other interfaces required by your system specifications.
See
Defining an interface on page 89.
Once you have defined your interfaces, you can define a Primary Management IP address
(PMI). The PMI is the IP address which the G250/G350 uses to identify itself when
communicating with other devices, particularly the Media Gateway Controller (MGC).
Management data intended for the G250/G350 is routed to the interface defined as the PMI.
You can use any interface as the PMI. For instructions on how to define the PMI, see
Configuring the Primary Management Interface (PMI) on page 90.
Once you have defined a PMI, you must register the G250/G350 with an MGC. The MGC is a
call controller server that controls telephone services on the G250/G350. The MGC can be
internal or external. See
Configuring the Media Gateway Controller (MGC) on page 92.
Once you have performed these steps, the G250/G350 is ready for use. Other configuration
tasks may also have to be performed, but these steps depend on the individual specifications of
your G250/G350 and your network.
Most G250/G350 configuration tasks are performed using the G250/G350 CLI. Avaya also
provides several GUI applications that are designed to perform the basic configuration tasks
described in this section. See
Configuration using GUI applications on page 35.
G350-001(super)# interface usb-modem
G350-001(super-if:USB-modem)# ip address 10.3.3.2
Done!
