25 MANAGING THROUGH THE CANOPY NETWORK
UPDATER TOOL (CNUT)
The Canopy Network Updater Tool manages and automates the software and firmware
upgrade process for Canopy radio and CMMmicro modules 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.
25.1 CNUT FUNCTIONS
The Canopy Network Updater Tool
◦ automatically discovers all Canopy network elements
◦ executes a UDP command that initiates and terminates the Autoupdate mode
within APs. This command is both secure and convenient:
− For security, the AP accepts this command from only the IP address that you
specify in the Configuration page of the AP.
− 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
− your entire network.
− only elements that you select.
− only network branches that you select.
◦ provides a Script Engine that you can use with any script that
− you define.
− Canopy supplies.
25.2 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
◦ organizes the display of elements (for example, by region or by AP cluster).
◦ allows you to
− perform an operation on all elements in the group simultaneously.
− set group-level defaults for telnet or ftp password access and SNMP
Community String (defaults that can be overridden in an individual element
when necessary).
25.3 NETWORK LAYERS
A typical Canopy network contains multiple layers of elements, each layer lying 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.
