The DHCP client table is only displayed when the DHCP server is enabled. The table will display the
host name, the allocated IP address, the host MAC address and the address lease expiration time for each
computer registered by the DHCP server.
Note that until the terminal has acquired lock on the forward link and received the system time via the
Time and Date Table (TDT) from the Gateway, it will have no information of the current time. The
DHCP server will in this situation only lease IP addresses to the LAN hosts for 15 minutes until the
system time is set. Lease expires
In less than 15 minutes
message will be displayed in the
DHCP client table.
7.2 Changing the SatLink Terminal LAN Interface IP address
If the IP address of the SatLink Terminal LAN Interface is changed, the IP addresses of all end-user
devices that are connected to the SatLink Terminal LAN must be updated correspondingly.
This also applies to those end-user devices that have obtained their IP addresses automatically from the
DHCP server. As the end-user devices will not normally issue a request to the DHCP server before the
lease-time of their IP addresses has expired, an IP address update of these devices must be manually
triggered by the end-user.
For example, to trigger a PC running MicroSoft Windows OS to request a new IP address from the DHCP
server, the end-user can issue the command
ipconfig /renew in the DOS command window.
If the end-user device does not have provisioned means for manually triggering a DHCP request for IP
address update, please power off and on again the end-user device. This will normally result in the end-
user device requesting the Terminal DHCP server for an IP address as part of the end-user device
initialisation process.
