Backup Cisco Network Equipment Running Configuration through Telnet Automatically

1. Create routerlist.csv file like the following.

Name,IP,Group
TORR-MPLS,172.X.X.X,HQs
HQSWT_LAN-248,172.X.X.X,HQs
HQSWT02-2,172.X.X.X,HQs
HQ-Edge02,172.X.X.X,HQs
NY-Edge01,192.X.X.X,NY
NY-Edge02,192.X.X.X,NY
NJ-Edge01,192.X.X.X,NJ
NJ-Edge02,192.X.X.X,NJ


2. Place the tftpserver.exe program on the subfolder named tftpsrv.
