Hi everyone again,
I read some documentation about zabbix and their different configurations.
In my scenario, i have Zabbix Agent active configuratio, i use the comunication with Zabbix agent for data gathering - a bit different of SNMP agent.
Zabbix agent has a supported item keys supported by platform:
https://www.zabbix.com/documentation/4.0/manual/appendix/items/supported_by_platform
Actualy, have no item theht return "port status" value Up/Down on that configuration.
I also saw another way when I edit the "User Parameters" at zabbix_agentd:(https://stackoverflow.com/questions/17716431/how-to-monitor-network-card-link-link-status-in-zabbix) but without success.
Anyway, if someone have another idea, i will really appreciate.
