If the word Up appears beside the router in the connections list, Site
Manager can communicate with the router. If Down appears, you must
check the router IP configuration or the router cabling, or both, to determine
why Site Manager cannot communicate with the router.
About ARN configuration files
Router configuration information is stored in a file on the router itself.
Several configurations can be saved on the router by creating different
configuration files. When the router boots up from a power off condition, it
looks for a configuration file named config and uses the information found
in this file to configure the router. For this reason, it is best to avoid making
changes to this file directly. The procedures described in this document
always save the configuration to a file named ccmis.cfg while it is being
created and tested. When the configuration is verified to work, it is copied to
the config file so that if the ARN is power cycled, it boots the last tested
version of the ccmis.cfg file.
A configuration file named ti_arn.cfg resides on the ARN that is a copy of
the original config file as it was shipped from the factory. If you ever need to
go back to a clean configuration, ti_arn.cfg can be booted or copied over the
config file.
There are two ways to use Site Manager to modify a router configuration.
The first method (Remote File method) allows you to select a particular
configuration file on the router, make changes to it, and then save it back to
the file. The router must then be rebooted to begin running the modified
configuration. The second method (Dynamic method) modifies the running
configuration and can be saved to a file when all necessary changes are
made. The Dynamic configuration method is used in this document to
perform router configuration because the Remote File method requires that
the Trivial File Transfer Protocol (TFTP) is used between the router and the
Site Manager PC to transfer the configuration file to and from the router.
Because many companies disable the TFTP protocol in their network
because of its insecure nature, the Dynamic configuration option is a more
universally available method.
