./classmap-policy-discover.php IPADDRESS "-v2c -c COMMUNITY" 

IPADDRESS is the adress of the cisco device
"-v2c -c COMMUNITY" are snmpwalk parameters

will discover definded class policies
 (e.g. 
.1.3.6.1.4.1.9.9.166.1.7.1.1.1.1593 "name1"
.1.3.6.1.4.1.9.9.166.1.7.1.1.1.3463889 "name2"
.1.3.6.1.4.1.9.9.166.1.7.1.1.1.15715633 "data1"
 )

and return SNMP OID suffixes for the QoS counter, according QoS enabled interface and policy name ..
 (e.g.
#IFNAME_QOS}":"GigabitEthernet0\/0.8","
#QOSCN_OIDSUFFIX}":"45.38766593","
