Configuration overview
If you intend to use a USB modem to connect to the G350, you should also assign an IP
address to the USB interface. It is not necessary to include a subnet mask.
Note:
The USB interface is not supported in the current version of the G250.
Note:
To assign a new IP address to the USB interface:
1. Use the interface USB command to enter the USB context.
2. Use the ip address command to define a new IP address for the USB interface.
The following example assigns to the USB interface an IP address of 10.3.3.2:
G350-001(super)# interface USB
G350-001(super-if:USB)# ip address 10.3.3.2
Done!
You must also make sure the G250/G350 is properly configured for whichever methods you
intend to use for accessing the G250/G350. For information on accessing the G250/G350, see
Accessing the Avaya G250/G350 Media Gateway
Your next step should be to define the other interfaces required by your system specifications.
See Defining an interface
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)
Once you have defined a PMI, you must register the G250/G350 with an MGC. The MGC is a
media server (call controller) that controls telephone services on the G250/G350. The MGC can
be internal or external. See
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
