Hide unused network interfaces

[ajhalls]

I am interested in filtering out network interfaces that aren't connected to make things a bit simpler. I tried the filter

{#SNMPVALUE} : ^u|^1

on this page:https://www.zabbix.com/forum/showthread.php?t=37656

I added it to the filter on "Template OS Linux: Network interface discovery" but that just hides all network interfaces. I am not sure if there have been some updates in how I should filter that out in Zabbix 3.0.

"Template OS Linux" is not use SNMP.

If you want filterling with "Template OS Linux",
I think you must change "Network interfaces for discovery" in "Regular expressions".

Thank you so much for you reply! You are actually the first to help me since I started using Zabbix a week ago. I removed all filters under discovery and under "Administration -> General -> Regular expressions: Network interfaces for discovery" Added

^up	[Result is TRUE]

I tried it a couple different ways such as "Result is FALSE -> ^down|^2" or "Result is TRUE -> ^u|^1" but so far nothing seems to make a difference. Under "Latest Data" it shows it still checking all interfaces as you can see in the attachment.

After making these changes do I need to remove and reconfigure the host to eliminate cached settings? I have it updating every 60 seconds now, but I made those changes nearly 12 hours ago, so I would think nearly everything would have refreshed by now if it was going to on its own.
