Resetting a trigger from a different snmp trap

[Muadeeb]

Probably a pretty basic thing to do, but my Google-fu is failing me. I have a device monitored via SNMP which sends a trap (which I am receiving in Zabbix) on a link failure, and a different trap on link restoration. I want the trigger to alert on link failure, and then clear on link up. I tried using

{Dragonwave Template:snmptrap["IF-MIB::linkDown"].regexp(IF-MIB::linkUp)}=0 or {Dragonwave Template:snmptrap["IF-MIB::linkDown"].regexp(IF-MIB::linkDown)}=1

But that doesn't appear to work.

I'm using v3.0.10 with the python handler to deal with the traps. And, yes, the names are resolving to OIDs.

Figured out how to do it by looking at the hysteresis examples.

({Dragonwave Template:snmptrap["IF-MIB::linkDown"].regexp(.*)}=1 and
{TRIGGER.VALUE}=0)
or
({Dragonwave Template:snmptrap["IF-MIB::linkUp"].regexp(.*)}=0 and
{TRIGGER.VALUE}=1)

Thanks for the help!
