Task 3: Upgrading the software version and
using CNUT
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 cluster).
Allows you 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 are behind an AP and thus, in this context,
at a lower layer than the AP. Correctly portraying these layers in Network Updater
is essential so that Network Updater can perform radio and AP 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
Set SNMP Accessibility
Reset Unit
