Using name instead of index

Very good!

I have made a little change in order to use interface name instead of index number. My changes:

index=`snmpwalk -v2c -c $snmpstring $host IF-MIB::ifName | awk -v PORTNAME=”$interface$” ‘$0 ~ PORTNAME {split($1,array,”.”); print array[2]}’`

# current value
trafbyteIn=`snmpget -v2c -c $snmpstring $host 1.3.6.1.2.1.31.1.1.1.6.$index |awk {‘print $4’}`
trafbyteOut=`snmpget -v2c -c $snmpstring $host 1.3.6.1.2.1.31.1.1.1.10.$index |awk {‘print $4’}`
