SECTION 4 " Configuration

The class identifier string for the access point is “Norand Access Point.” Servers use this string to identify the access point.

Bootp Operation

The access point can also accept addresses from a Bootp server identified in the DHCP server name field. An address offer from a Bootp server is treated as if it were an infinite lease from a DHCP server.

Networks With DHCP and Bootp Servers

If the DHCP server name is configured as “”, the access point responds to either DHCP or Bootp servers. The access point gives preference to DHCP offers. If a Bootp reply arrives at the access point before any DHCP offers are received, the access point waits an additional 4 seconds for a DHCP offer before responding. If a DHCP offer is received within the 4-second period, the Bootp reply is ignored and the DHCP offer is accepted.

Handshaking

When the access point responds to a DHCP or Bootp server, it broadcasts a single ARP request to the address offered. If no ARP response is received within 3 seconds, the access point assumes the IP address is unique and completes the negotiation for that address. If an ARP reply is received before the timeout, the access point assumes the address is a duplicate and declines the offer.

Infinite Leases

A DHCP server may be configured to grant an infinite lease to the access point. A Bootp grant is always treated as an infinite lease. The access point stores the IP address, subnet mask, and default router in the EEPROM configuration register and disables DHCP. These settings are maintained if the access point is powered off or rebooted through the ROM command monitor. To restore DHCP client operation, reconfigure the IP address to 0.0.0.0.
