Problem with LLD / SNMP

[errorsmith]

Hi

I'm trying to set up a lld using snmp for some switches.
For starters, I followed the tutorial / documentation. Unfortunately I'm getting this error:

item "edgecore:ifDescr" became not supported: OID "discovery[{#SNMPVALUE},IF-MIB::ifDescr]" contains unsupported parameters.

After googling, reading old bugreports (all of them closed), I'm at the end of my knowledge. As far as I understood, zabbix has problems interpreting the name "IF-MIB::ifDescr" to its corresponding numeric OID. Or the underlying net-snmp components. But why? I can snmpwalk the device in question using the symbolic names (IF-MIB::ifDescr) and the numeric OID (0.1.3.6.1.2.1.2.2.1.2.1) as the zabbix user, so the underlying net-snmp should know about the installed mib.

Please advise me whats wrong here.

Current config:
zabbix 2.4 on FreeBSD 10.1, compiled with snmp (ammong others)
net-snmp 5.7 installed.
config of the discovery rule:

name: find-ports
type: snmpv2 agent
Key: ifDescr
snmp oid: discovery[{#SNMPVALUE},IF-MIB::ifDescr]
snmp community: public

not mentioned values are on default.

Thaks in advance for any help

Try using just "IF-MIB::ifDescr" as the OID instead of the "discovery[..."

Thank you, this worked fine.
So basically the documentation ist wrong:
In chapter https://www.zabbix.com/documentation...y_of_snmp_oids there is a screenshot wich clearly shows that "disvovery" part in the field SNMP OID.

Someone should correct this...

Anyway, it works now.

kind regards,
