Problem 3 - If we cannot reach the tftp server it does not give more error information as to why the Ping test failed.

kashishg-mac:AU kashishg$ ./accelerated_upgrade.py -l admin -p C1sco123 -d 10.52.234.37 -r tftp://10.52.230.63 -f ./Packagelist.rtf --pre-upgrade-checks-only

FIXED THIS BY CHANGING ping_test.py file.

 if (out.find('Success rate is 0') != -1 or
        out.find('Bad hostname or protocol not running') != -1 or 
        out.find('UUUUU') != -1):
        print "Could not ping the TFTP server address.Check connectivity"   ( newline added)
        return -1

Problem 4 - No where to specify the vrf to use to reach the TFTP server. Used a workaround but need a better solution to pass the VRF.

I fixed this manually by changing the ping_test.py script.

if ( len(list[0]) if list[0] else list[1] in protocol):
        #cmd="run ping -p 0xf -z 0xa "+ipaddr[0]
        cmd = "ping vrf Mgmt-intf"+ipaddr[0]
