Passing macro from one LLD Discovery to Another

[thelettere]

Hello,

Using Zabbix 2.4.4 and attempting to monitor QLogic 5602 FibreChannel switch.

The QLogic switch inserts the WWN of the switch into the OIDs to be monitored.

I have a LLD Discovery Rule that uses the advsnmp.discovery script to return the WWN portion of the OID based on a filter.

However, I need to use this WWN value for additional Interfaces and Sensor discovery rules. Is there a way to pass the value from one Discovery rule to other Discovery rules?

Existing Discovery rule below.
