result=$(snmpwalk -v 3  -u WANDL_SU -a MD5 -A vfipmpls -x DES -X VfIpMpLs -l authPriv $f1 2>/dev/null|awk -F"[: ]" '$0 ~ F2awk{print $3; exit}' F2awk="$f2")

If you tell us where to get the IP address then this might be doable. pamu assumed it to be one of your input parameters. If that's true, adapt the awk command like
Code:
awk -F"[: ]" '$0 ~ F2awk{print F1awk, F2awk, $3; exit}' F2awk="$f2" F1awk="$f1"

It won't work as per the OP's comment.

Actually, I'm having a difficult time getting what the requestor really needs. If snmpwalk outputs the next device if actually requested device's data are not found, then both approaches will fail unless snmpwalk outputs sth. to compare to the requested device.
Pls post snmpwalk output for success and for failure.

Hi All,

thanks for the reply..actually when I use script given it gives output of only those devices for which snmpwalk works, it is not giving out anything else in the otput file(i.e. devices for which snmpwalk doesn't work..) in general when we do snmpwalk i success we should get either our output and in case of failure it is Response timeout.
..hope this clarifies requirement..
