The IP address range start address („ip.start.requested‟ in the CLI) must be one of the
following values: 1, 33, 65, 97, 129, 161, 193, 225.
The IP address range size („ip.size.requested‟ in the CLI) must be one of the following
values: 31, 63, 127, 255.
The IP address range size and start address must be chosen such that the address
segment does not cross a netmask boundary. Table 9 lists allowed combinations.
The address spaces for enabled interfaces must start at different addresses.
The address spaces for enabled interfaces should not overlap.

Table 9. Allowed address segment start address and size combinations
Each of the enabled interfaces‟ address segments should be configured to avoid overlap with
the other interfaces‟ address segments. In the case where a node is not configured such that
this requirement is met, address spaces will be automatically reduced in size to prevent
overlap.
CLI
In the first example below, the Ethernet interface is set to use the entire class C address space
(this requires that all the other client interfaces, wlan1-4, are disabled). In the second example,
the Ethernet interface is set to use the upper half of the class C address space.

eth0> set ip.start.requested=1
eth0> set ip.size.requested=255
> use eth0

The actual start address and size of a segment are accessible via the „ip.start.actual‟ and
„ip.size.actual‟ parameters.
