*<interface> **
**        <name>Get GEPON Interfaces Statistics</name> **
**        <description>Queries a statistics for interfaces CNI e PON in 
plataform GEPON Furukawa FKC16</description>**

**<index_order>fkc16OltInformationIndex</index_order> **
**<oid_num_indexes>.1.3.6.1.4.1.10428.8.1.1.9.1.1.0</oid_num_indexes> **
**<index_order_type>numeric</index_order_type> **

**<name>Index</name> **
**<method>walk</method> **
**<source>value</source> **
**<direction>input</direction> **

**</fkc16OltInformationIndex> **
**</fields> **
**</interface>*


Via gui of cacti using verbose query its display
*+ Running data query [14].
+ Found type = '3' [SNMP Query].
+ Found data query XML file at 
'/usr/share/cacti/site/resource/snmp_queries/gepon.xml'
+ XML file parsed ok.
+ Executing SNMP get for num of indexes @ 
'.1.3.6.1.4.1.10428.8.1.1.9.1.1.0' Index Count: 3
+ Executing SNMP walk for list of indexes @ 
'.1.3.6.1.4.1.10428.8.1.1.9.1.2.1.1' Index Count: 0
+ No SNMP data returned*

Its test via line command.

root@apolo:/usr/share/cacti/resource/snmp_queries# snmpget -c public -v 
1 172.16.30.11 .1.3.6.1.4.1.10428.8.1.1.9.1.1.0
iso.3.6.1.4.1.10428.8.1.1.9.1.1.0 = INTEGER: 3
root@apolo:/usr/share/cacti/resource/snmp_queries# snmpwalk -c public -v 
1 172.16.30.11 .1.3.6.1.4.1.10428.8.1.1.9.1.2.1.1
iso.3.6.1.4.1.10428.8.1.1.9.1.2.1.1.1 = INTEGER: 1
iso.3.6.1.4.1.10428.8.1.1.9.1.2.1.1.2 = INTEGER: 2
iso.3.6.1.4.1.10428.8.1.1.9.1.2.1.1.3 = INTEGER: 3
root@apolo:/usr/share/cacti/resource/snmp_queries#
