Chapter 10: Client Addressing Schemes

TR0190 Rev. A1 62

• Each active client access interface must be assigned an address segment.

• The IP address range start address (‘ip.implicit.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.implicit.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 8 lists allowed combinations.

• The address spaces for enabled interfaces must start at different addresses.

• The address spaces for enabled interfaces should not overlap.

Table 8. 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 an EL-500 is not configured such

that this requirement is met, address spaces will be automatically reduced in size to prevent

overlap.

CLI

The start and size of client address spaces are set with the ‘ip.implicit.start.requested’ and

‘ip.implicit.size.requested’ parameters in the ‘wlan1’, ‘wlan2’, ‘wlan3’, and ‘wlan4’ interfaces.

Refer to Table 8 for allowed values for these parameters.

In the first example below, the ‘wlan1’ interface is set to use the entire class C address space

(this requires that all the other client access interfaces, wlan2-4, are disabled). In the second

example, the ‘wlan1’ interface is set to use the upper half of the class C address space.

> use wlan1

eth0> set ip.implicit.start.requested=1

eth0> set ip.implicit.size.requested=255

> use wlan1

eth0> set ip.implicit.start.requested=129

eth0> set ip.implicit.size.requested=127
