- XP Machine with TFTPD ip is 192.168.2.60
- Copy cme-full-4.3.0.0.tar into C3725 Router. I tried another tftp server Pumpkin, but it gave me an error. FTP service should be faster than tftp. TFTP took 1 hour and 44 minutes to get whole package extracted. This lab is using tftp to make things simple. From C3725 router, run following three commands:
erase flash:
format flash:
archive tar /xtract tftp://192.168.2.60/cme-full-4.3.0.0.tar flash:
