How to configure Zabbix (Zabbix) 4.0.18 to use SNMP on Cisco 6500 Sup2T

[JFFJJFFJ]

Dear All,

I am trying to configure Zabbix to see the realtime traffic on Cisco 6500 Switch, with Supervisor 2T.
I am alredy tryed to download the Cisco 6500 templates from the zabbix community:

template_cisco_6500.yaml

and I have tryed also,

template_cisco_6500.xml

But when I try to import them I hot this error:

Invalid tag "/zabbix_export/version": unsupported version number. [conf.import.php:167 → CFrontendApiWrapper->import() → CApiWrapper->__call() → CFrontendApiWrapper->callMethod() → CApiWrapper->callMethod() → CFrontendApiWrapper->callClientMethod() → CLocalApiClient->callMethod() → call_user_func_array() → CConfiguration->import() → CXmlValidator->validate() in include/classes/api/services/CConfiguration.php:148]

I should updte my Zabbix version, but it is the first time that I use it, I do not know how proceed.

I have also configured my own basic template with SNMP that use OID 1.3.6.1.2.1.2, the SNMPWALK works but I do not see any data in the Zabbix Graphs.

Could you help me pls?

Bye,

JF.
