How to deal with linkStatus trap and triggers ?

[skiny13]

Hi,

I have configured my Zabbix server to handle the SNMP traps from my Cisco switches. I am only interested by the linkStatus traps (up/down).

The configuration is correct, but i'm still facing a problem.

I would like to have a trigger when an interface changes status, but I do that, the trigger won't ever be false again.

Here's the trigger expression I use:

{switch-hostname:snmptrap["@IP"].str(DOWN,#1)}=1

And the string received by Zabbix:

17:06:44 2015/04/27  .1.3.6.1.6.3.1.1.5.3 Normal "Status Events" @IP - Interface GigabitEthernet0/17 changed state to DOWN

I have also tried to use the "nodata()" function to remove the trigger if no traps are received within an hour, but it is not working correctly...


Does anyone have an idea ?

Thank you.
