Chapter 9: Client Addressing Schemes
TR0153 Rev. E1 69
• 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 EnRoute500 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 ‘eth0’, ‘wlan1’, ‘wlan2’, ‘wlan3’, and ‘wlan4’
interfaces. Refer to Table 8 for allowed values for these parameters.
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 access 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.
