Interface Settings: If you make any changes to the IP Address, Subnet Mask and/or
Default Encoder fields, the Apply and Cancel buttons become active. The changes only
take effect when you press the Apply button. Pressing the Cancel button reverts the
fields back to their original values. Note that the 9223-SA will check the consistency of
the data entered and will reject invalid combinations (i.e., combinations where the
gateway is outside the interface subnet). Once the Apply button is pressed, a status
message appears just below the Cancel button, as follows:
•
Interface speed: Configures the speed of the interface. The 9223-SA Ethernet
interfaces only support two modes: 100 Mb/s Full-Duplex and 1 Gb/s Full-Duplex

.
o Auto-Negotiate: The Ethernet port will auto-negotiate the speed.
o 100 Mb/s Full-Duplex: Force the port to 100Mb/s Full-Duplex mode. Note that
the port will still perform auto-negotiation, but it will only advertise this mode.
o 1Gb/s Full-Duplex: restrict the operation to 1Gb/s Full-Duplex mode. Note that
the port will still perform auto-negotiation, but it will only advertise this mode.
Notes:
o If the 9223-SA streaming Ethernet interfaces are connected to a 10 Mb/s switch,
hub, or network feed, link will not be established and the port will not recognize
the connection.
o If you select 100 Mb/s Full-Duplex or 1 Gb/s Full-Duplex and the
corresponding streaming Ethernet interface is connected to a switch, hub or
network feed that does not support the selected speed, link will not be established
and the port will not recognize the connection.
o If the interface speed is set to Auto-Negotiate, the streaming Ethernet port will
allow link to be established in 100 Mb/s Half-Duplex mode. However, this will
be flagged as a warning.
Network Configuration DNS Tab
The DNS tab allows manual configuration of up to two DNS servers. They do not need to be in
the same subnetwork as the streaming ports, as long as at least one default gateway is configured.
DNS is only used in conjunction with the RTMP output functionality. If you are not using
RTMP, there is no need to configure DNS servers.

Support for 10 Mb/s and Half-Duplex modes has been discontinued, as these are unsuitable for MPEG transport
over IP applications. Moreover, any modern switch supports at least 100 Mb/s Full-Duplex.
