Configuration Save and Restore
The MGX 8220 shelf provides Save and Restore functions which are performed using the TFTP
facility.
The Save function allows a user to copy a service module’s current configuration file (which is saved
on a disk on the ASC) to a network file system. The Restore function allows a user to copy a service
module’s configuration file from the network file system to the ASC’s disk. Using these functions,
the configuration files for MGX 8220 service modules can be backed up to an independent network
system and later restored if the configuration files in the MGX 8220 shelf become lost or corrupted
or if the configuration needs to be restored to a previous version.
