4 IP Network Planning

CAP-NAP backhaul equipment, if provisioned
CAP and NAP UPS, if provisioned
Ethernet switches
SNMP manager, if provisioned
Gateway (NAP) router Ethernet port
The number of CAPs is limited by the capacity of the gateway (NAP) router. WaveRider
suggests allocating a minimum of 256 addresses to the CCU Ethernet subnet, which
accommodates 15 CAPs and requires a 24-bit subnet mask.
4.2 IP Planning Process
For reference purposes, an example of an IP Plan is included in Appendix I on page 241.
Before you configure and operate your LMS4000 900 MHz Radio Network, you must define
your IP addressing scheme based upon the following guidelines and recommendations:
WaveRider recommends that LMS4000 subnets use IP addresses that have been
reserved for private networks. WaveRider recommends 192.168.10.0 /24 for the CCU
Ethernet subnet, and 10.0.0.0 /22 for the CCU radio subnet, since these addresses
are quite distinct from each other. If you are already using 10.0.0.0 /22, then you can
alternatively use 172.16.0.0 /22.
The IP addressing plan for the CCU Ethernet subnet should allow for growth to a
maximally equipped system, as follows:
CCU Gateway IP address one
NAP equipment IP addresses up to 10
CAP equipment Ethernet IP addresses number of CAPs x 16
For a 15-CAP system, set aside 251 IP addresses, which requires a subnet with a 24-
bit mask, for example 192.168.0.0 /24.
In the example shown in Appendix I on page 241, the IP addressing plan for the CCU
Ethernet subnet is summarized as follows:
CCU Ethernet Subnet 192.168.10.0 /24
Gateway Router 192.168.10.1 /24
NAP Switch 192.168.10.5 /24
NAP UPS 192.168.10.6 /24
SNMP Manager 192.168.10.7 /24
CAP01, CCU01 Ethernet port 192.168.10.11 /24
CAP01, CCU02 Ethernet port 192.168.10.12 /24
CAP01, CCU03 Ethernet port 192.168.10.13 /24
CAP02, CCU01 Ethernet port 192.168.10.27 /24

CAP15, CCU02 Ethernet port 192.168.10.236 /24
