The address spaces for enabled interfaces should not overlap.
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 configured such that this
requirement is not met, address spaces will be automatically reduced in size to prevent
overlap.
CLI
In the example below, the WLAN interfaces are set up to use the lower half of the class C
address space. This assumes that the Ethernet interface is either used for gateway purposes
or is assigned to an address segment in the upper half of the class C network.
> use wlan1
wlan1> set ip.start.requested=1
wlan1> set ip.size.requested=31
wlan1> use wlan2
wlan2> set ip.start.requested=33
wlan2> set ip.size.requested=31
wlan2> use wlan3
wlan3> set ip.start.requested=65
wlan3> set ip.size.requested=31
wlan3> use wlan4
wlan4> set ip.start.requested=97
wlan4> set ip.size.requested=31
The actual start address and size of a segment are accessible via the „ip.start.actual‟ and
„ip.size.actual‟ parameters. These may differ from the requested values if incompatible
requested values have been set for different interfaces.
Web GUI
The eth0 address segment start address and size can be set via the web interface using the
“DHCP” sub-tab on the “DHCP” tab on the “System Parameters” page (see Figure 33).
