Configuring IP Addresses
The SIT makes use of three IP addresses.
• The ethernet IP address is the IP address on the ethernet interface port (see
section
1.4
). This IP address and mask are used by the LAN (terrestrial network) connected
directly to the IDU.
• The satellite OAM (operation, administration and maintenance) IP address is the SIT
IP address on the satellite interface port. It is used for SIT management (OAM) pur-
poses.
• The satellite traffic IP address is used for IPSec tunnelling and for RADIUS authenti-
cation.
Use the Network Configuration page to view and modify these IP addresses.
The table below describes the parameters in the Network Settings section of the page.
Table 2:
Parameter
Description
SIT Ethernet I/F IP
Address
IP address on the ethernet interface port (see
section 1.4
), used by the LAN
(terrestrial) network connected directly to the IDU.
The factory default setting is “10.10.10.10”.
SIT Ethernet I/F IP
Mask
Associated net mask for SIT ethernet. This mask determines the SIT LAN
subnet.
The factory default setting is “255.255.255.0”.
SIT Satellite I/F
OAM IP Address
The SIT IP address on the satellite interface port. It is used by the hub for
SIT management (OAM) purposes.
The factory default setting is “172.16.0.1”.
SIT Satellite I/F
Traffic IP Address
The SIT IP address
for IPSec tunnelling and for RADIUS authentica-
tion.
The factory default setting is “10.5.5.5”.
OAM Release
Timeout
OAM VCC will be released if no OAM data is transmitted for the duration
of the timeout (in msec). This timer is valid only when the SIT state is
“OamActive”. If the time expires, the SIT state will then go from “OamAc-
tive” to “Initialized”. A value of “0” disables the timeout.
Traffic Release
Timeout
Traffic VCC will be released if no traffic is transmitted for the duration of
the timeout (in msec). This timer is valid only when the SIT state is
“Active”. If the time expires, the SIT state will then go from “Active” to
“OamActive”. A value of “0” disables the timeout.
