modify the subscriber IP address settings. The following table lists all commands
available in this mode.
Table 16: CLI - ipAddress - IP Address Commands
Command
Description
set
Change IP address parameter settings.
Address
: IP address assigned to subscriber. Static address only.

: 255.255.255.0
Example: Use the following command to set a static IP address and
mask: set Address 192.168.20.33 Mask 255.255.255.0
show
Display the current IP address settings. For example:
Structure --- <<SS IP Address Data>>
Address:............192.168.25.100
Mask:...............255.255.255.0
reset
Reset the IP address to factory default. Requires confirmation.
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 an 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 its system
clock with the time received from the ToD server. 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 IP address previously assigned by the
DHCP server, 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, then the
DHCP server may assign a new IP address to the subscriber. You can ensure that
your subscriber will always receive the same IP by either making the lease
timeout indefinite, or by making a static address reservation for your subscriber
(if your DHCP server supports this feature).
