SU Configuration
SU configuration can be done in server mode or in local mode:
• In local mode, the SU’s configuration is performed using the Aperto Installation
Manager (AIM). No configuration file is downloaded from the BSU’s TFTP server.
• In server mode, subscriber equipment is provisioned using the WaveCenter Config-
uration Manager, as described in the
PacketWave 1000 Base Station Unit Installa-
tion, Configuration, and Operation
manual. On boot-up, after getting address and
file information from its assigned DHCP server, the PacketWave 200 downloads its
configuration file from the base station’s TFTP server.
PacketWave 200 should be appropriately be configured in Server mode. They receive their
IP address and configuration information from a DHCP server. DHCP entries should be
reserved to the MAC address of the deployed/provisioned Aperto equipment. PacketWave
200 should be configured with infinite leases. This is highly appropriate since you never
want to give this IP address to another device in the network.
Some configuration of the PacketWave 200 can be performed via the Web GUI and SNMP.
If desired, these configuration changes can be made permanent by uploading them to the
SU configuration file on the TFTP server. (If configuration changes are made via the Web
GUI or SNMP but not uploaded, they will be lost when the PacketWave 200 is reset or re-
powered.) Uploading configuration changes made via the Web GUI or SNMP is a conve-
nient way to modify the configuration file of an in-service PacketWave 200.
Configuration uploads from the Web GUI and SNMP require that the TFTP server be
configured to accept uploads.
NOTE: Advanced Installation Manager (AIM) will allow the installer to configure
a Subscriber Unit (SU) in local mode by providing appropriate IP addresses and con-
figuration parameters. It always uses the default configuration file for the unit.
Aperto highly suggests only using server mode for the Subscriber Unit.
Built-In Server, Client, Agent, and Router Functions
Servers, agent/client, and router functions are built into PacketWave 200:
• DHCP Client — All PacketWave Series 200 models include a Dynamic Host
Configuration Protocol (DHCP) client for local address management by the Base
Station Unit’s assigned DHCP server.
• DHCP Server — PacketWave 220 and 230 models include a Dynamic Host
Configuration Protocol (DHCP) server for local address management.
• NAT Server — PacketWave 220 and 230 models include a built-in NAT (Network
Address Translation) server.
• IP Router — PacketWave 230 models include a built-in IP router.
• SNMP Agent — All PacketWave Series 200 models include an SNMP agent for inte-
gration of the PacketWave network into an SNMP management system.
