Local Ethernet Port (Secondary Management) IP
All factory-shipped subscriber systems have the following IP addresses assigned to the
local Ethernet port:
Fixed:
192.168.101.1 (well-known, can not be modified)
Default:
192.168.101.2 (can be modified using CLI)
Over-the Air (Secondary Management) IP
When a subscriber is enabled for remote management (
managedSS=1
)
its over-the-air
secondary management IP address can be assigned only through the base station acting as
a DHCP relay agent. The DHCP server and a Time-of-Day (ToD) server (specified in the
obtained lease) must be located on the network connected to the base station Ethernet
port. The subscriber can not use any DHCP or ToD server on the network connected
directly to the subscriber Ethernet port.
The DHCP exchange includes a request for the address of a ToD server, and the time
offset (option 2) specifying the time zone where the subscriber is operating (seconds from
GMT). After the subscriber acquires a DHCP lease time, it attempts to contact the ToD
server. If successful, the subscriber updates the system clock with the received time. If a
ToD server cannot be reached the subscriber initializes its system clock to the default
time of midnight January 1, 1970 GMT.
DHCP Issues
The subscriber does not keep a record of the previously assigned IP, and the IP request
field is empty during its initial request. If the lease has expired since the last time the
subscriber requested an address the DHCP server may assign a new IP address. You can
ensure that your subscriber will always receive the same IP by 1) making the lease
timeout indefinite, or 2) creating a static address reservation for your subscriber (if your
DHCP server supports these features).
