• An md5 checksum calculator utility for identifying corruption of downloaded image files before
Network Updater is set to apply them.
Network element groups
With the Canopy Network Updater Tool, you can identify element groups composed of network
elements that you select. Identifying these element groups does the following:
• Organizes the display of elements (for example, by region or by AP/BHM cluster).
• Allows to:
o
Perform an operation on all elements in the group simultaneously.
o
Set group-level defaults for ftp password access and SNMP Community String
(defaults that can be overridden in an individual element when necessary).
Network layers
A typical network contains multiple layers of elements, with each layer farther from the Point of
Presence. For example, SMs (or BHS) are behind an AP/BHM and thus, in this context, at a lower layer
than the AP/BHM. Correctly portraying these layers in Network Updater is essential so that Network
Updater can perform radio and AP/BHM cluster upgrades in an appropriate order.
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 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:
• Gather Customer Support Information
• Set Access Point Authentication Mode
• Set Autoupdate Address on APs/BHMs
•
Set SNMP Accessibility
• Reset Unit
