11 Network
This section describes the network-related configuration.
11.1 Ethernet Interface Configuration
The device's Ethernet connection can be configured, using the ini file parameter
EthernetPhyConfiguration, to one of the following modes:
When the device's Ethernet port is configured for Auto-Negotiation, the opposite port
must also operate in Auto-Negotiation. Auto-Negotiation falls back to Half-Duplex
mode when the opposite port is not in Auto-Negotiation mode, but the speed in this
mode is always configured correctly. Configuring the device to Auto-Negotiation mode
while the opposite port is set manually to Full-Duplex is invalid as it causes the device
to fall back to Half-Duplex mode while the opposite port is Full-Duplex. Any mismatch
configuration can yield unexpected functioning of the Ethernet connection.
When configuring the device's Ethernet port manually, the same mode (i.e., Half
Duplex or Full Duplex) and speed must be configured on the remote Ethernet port. In
addition, when the device's Ethernet port is configured manually, it is invalid to set the
remote port to Auto-Negotiation. Any mismatch configuration can yield unexpected
functioning of the Ethernet connection.
It's recommended to configure the port for best performance and highest bandwidth
(i.e., Full Duplex with 100Base-TX), but at the same time adhering to the guidelines
listed above.
Note: For remote configuration, the device should be in the correct Ethernet setting
prior to the time this parameter takes effect. When, for example, the device is
configured using BootP/TFTP, the device performs many Ethernet-based
transactions prior to reading the ini file containing this device configuration
parameter. To resolve this problem, the device always uses the last Ethernet
setup mode configured. In this way, if you want to configure the device to
operate in a new network environment in which the current Ethernet setting of
the device is invalid, you should first modify this parameter in the current
network so that the new setting holds next time the device is restarted. After
reconfiguration has completed, connect the device to the new network and
restart it. As a result, the remote configuration process that occurs in the new
network uses a valid Ethernet configuration
11.2 Configuring IP Network Interfaces
You can configure a single VoIP network interface for all applications, which includes
OAMP (management traffic), call control (SIP messages), and media (RTP traffic), or you
can configure multiple logical, IP network interfaces for these applications. A need often
arises to have logically separated network segments for these applications for
