CNUT functions
The Canopy Network Updater tool has the following functions:
Automatically discovers all network elements
Executes a UDP command that initiates and terminates the Auto-update 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.
CNUT supports HTTP and HTTPs
Allows you to choose the following 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/HTTPS 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,
