Hello all:
I'm setting up SNMP v2 discovery, but SNMP agents don't get discovered.
Manually created host with SNMP interface and generic SNMP template works, though. Interface shows green for this host, also shows latest data for its items.
Actions have conditions where (Discovery status=Discovered) or (Discovery rule = <SomeSnmpDiscoveryRule1>), etc. Operations are Add host, and Link to templates: Template SNMP Device, Template SNMP Generic, etc

Why is it that manually added host works fine, snmpwalk works ok, ips for SNMP agent are discovered, but when getting values for IF-MIB::ifDescr it timeouts? Timeout in zabbix_server.conf was the default 5, then I changed it to 10, now it's at 15.
Any ideas why it's timing out? That must be the reason for Add host and Link to template operations not being not performed when SNMP conditions are checked, right?
Thanks in advance.
