Cacti monitorando WLA 5000 via snmp

Pessoal estou com um probleminha para monitorar o travego do Ovislink wla 5000, é o seguinte, do cacti consigo consutar o rádio, ele recebe as informações:
SNMP Information
System: Linux WLA-5000AP 2.4.25-LSDK-5.1.0.42 #2 Wed Jan 30 14:27:31 CST 2008 mips
Uptime: 84085 (0 days, 0 hours, 14 minutes)
Hostname: IVONALDO

Porem quando testo debug:
Data Query Debug Information+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1'
+ No SNMP data returned
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'


O que pode ser? será que devo atualizar o tamplate no cacti? me ajudem...

Agradeço atenção de todos.
