Link down status only for selected ports in template Cisco

[Jacek B]

I have Zabbix 5.0.2.
In "Template Net Cisco IOS versions 12.0_3_T-12.2_3.5 SNMP"
I have trigger prototype "Interface {#IFNAME}({#IFALIAS}): Link down"
I want to check only selected ports by this trigger.
How can I resolve this problem?

Thanks,

I don't know if I understand what you mean by "want to check only selected ports by this trigger", but two things come to my mind:

1) If you don't want to monitor unused ports on your switch, shutdown them and create a rule in the discovery that excludes ifAdminStatus that are shut.
2) If you want to check the monitor data for the active triggers, you can filter them by name on Monitoring->Problems and put "Link down" in "Problem" Field, then you can click each Problem description and look at the History data.

I want monitor only ports connected to NAS and for the Servers another ports for the computer or laptops I'm not interested to monitored.

Go for option 01, but instead of filtering out ifAdminStatus, you gonna put some meaningful description on switch ports and filter in based on ifDescr or ifAlias based on how your switch works with snmp.
