IMPORTANT!
Correct layer information ensures that Network Updater does not
command an AP that is behind another AP/SM pair (such as in a remote
AP installation) to perform an upgrade at the same time as the SM that is
feeding the AP. If this occurs, then the remote AP loses network
connection during the upgrade (when the SM in front of the AP
completes its upgrade and reboots).
25.4 SCRIPT ENGINE
Script Engine is the capability in Network Updater that executes any user-defined script
against any network element or element group. This capability is useful for network
management, especially for scripts that you repetitively execute across your network.
The Autodiscovery capability in Network Updater finds all of your Canopy network
elements. This comprehensive discovery
◦ ensures that, when you intend to execute a script against all elements, the script
is indeed executed against all elements.
◦ maintains master lists of elements (element groups) against which you
selectively execute scripts.
The following scripts are included with CNUT:
◦ AP Data Import from BAM
◦ AP Data Export to BAM
◦ Set Autoupdate Address on APs
◦ Set SNMP Accessibility
◦ Reset Unit
