2.14 Auto Upgrade all APs Through Messaging

The Update ALL access points option upgrades or downgrades the firmware
of all associated APs with the same Net_ID (ESS) on the same subnet and
includes all recognized hardware platforms regardless of firmware version.
The initiating AP sends the correct filename for each Symbol platform.
The initiating AP does not send update commands to non-Symbol platforms.
Users can find the specific APs that have firmware upgraded or downgraded
on the Known APs screen. The time interval between the WNMP update
firmware commands for updating each AP is 2 seconds. This interval
prevents more than one AP from accessing the TFTP server and causing
network congestion.
The Ethernet TFTP upgrade method requires a connection between the AP
and PC on the same Ethernet segment. Verify the PC has a TFTP server
running on it. Running the server requires third party software like FTP PC/
TCP for DOS or OnNet™ for Windows.
The wireless TFTP upgrade method requires a connection between
the AP and a TFTP server. The TFTP server can be running on a Symbol
Spectrum24 device.
Updating the firmware requires a TFTP server running in the background.
