Using the Canopy Network Updater Tool (CNUT)
The Canopy Network Updater Tool (CNUT) manages and automates the software and firmware
upgrade process for a Canopy radio, CMMmicro, or CMM4 (but not its 14-port switch) across the
network. This eliminates the need for an administrator to visit each radio in the network (or each AP
while using the Autoupdate feature) to upgrade the modules.
CNUT Functions
The Canopy Network Updater Tool
automatically discovers all network elements
executes a UDP command that initiates and terminates the Autoupdate mode within APs. This
command is both secure and convenient:
o For security, the AP accepts this command from only the IP address that you specify in the
Configuration page of the AP.
o For convenience, Network Updater automatically sets this Configuration parameter in the
APs to the IP address of the Network Updater server when the server performs any of the
update commands.
allows you to choose among updating
o your entire network.
o only elements that you select.
o only network branches that you select.
provides a Script Engine that you can use with any script that
o you define.
o Cambium supplies.
configurability of any of the following to be the file server for image files:
o The AP, for traditional file serving via UDP commands and monitoring vai UDP messaging
o CNUT HTTP Server, for upgrading via SNMP commands and monitoring via SNMP
messaging. This also supports an option to either set the image order specifically for this file
server or to allow the AP to determine the order.
o Local TFTP Server ,for traditional file serving via UDP commands and monitoring via UDP
messaging. This supports setting the number of simultaneous image transfers per AP
the capability to launch a test of connectivity and operational status of the local HTTP and TFTP
file servers
an interface that supports efficient specification of the proper IP address for the local file server(s)
where Network Updater resides on a multi-homed computer
an md5 checksum calculator utility for identifying corruption of downloaded image files before
Network Updater is set to apply them.
