Auto Fallback To Wireless Mode; Dhcp Support - Symbol Spectrum24 AP-3020 Reference Manual

Depending on the setting, the AP can keep a list of frame types that it
forwards or discards when they reach it. The Type Filtering option prevents
specific frames (indicated by the 16-bit DIX Ethernet Type field) from being
processed by the AP . These include certain broadcast frames from devices
unimportant to the wireless LAN but take up bandwidth. Filtering out
unnecessary frames can also improve performance.

Auto Fallback to Wireless Mode

The AP supports an Auto Fallback to Wireless when the hardware Ethernet
connection fails or becomes broken. The AP resets itself and during
initialization attempts to associate with any other WLAP in the network. This
feature is available only if the WLAP Mode is enabled and the Ethernet
Timeout parameter is set to one.

1.3.3

DHCP Support

The AP uses Dynamic Host Configuration Protocol (DHCP) to obtain a leased
IP address and network configuration information from a remote server.
DHCP is based on BOOTP protocol. DHCP can coexist or interoperate with
BOOTP . An AP sends out a DHCP request searching for a DHCP server to
acquire the network configuration and firmware filenames. Because BOOTP
and DHCP are interoperable, whichever responds first becomes the server
allocating the information. The DHCP client automatically sends a DHCP
request every XX hours/days to renew the IP address lease as long as the AP
is running. (This parameter is programmed at the DHCP server. Example:
Windows NT servers typically are set for 3 days.) The AP can optionally
download two files when a boot takes place, the firmware file and an HTML
file, because firmware versions 4.00-31 and above support Web servers.
Users can program the DHCP or BOOTP server to transfer these two files
when a DHCP request is made.
When the AP receives a network configuration change or not able to renew
the IP address lease the AP sends out an SNMP trap.
