Using Another Machine as a TFTP Server
Configuring the EM server as a TFTP server is optional. You can alternatively choose to use a different
machine as the TFTP server, or not use the backup/restore functionality at all. If you choose to use
another workstation as a TFTP server, make sure that backup files are empty. You also need the
appropriate permissions set to allow read and write access. Backup files have the filename
CARMGRaa.bb.cc.dd, where aa.bb.cc.dd is the IP address of the router. A backup file is created for the
active Cisco router.
