I have SNMP items with dynamic indexes in Zabbix 1.8.10:

SNMP OID:
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.3"index","SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5"," FAN #1"

snmpwalk from zabbix machine:

snmpwalk -v2c -c xxx vdx01 SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.1 = STRING: "SLOT #0: TEMP #1"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.2 = STRING: "SLOT #0: TEMP #2"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.3 = STRING: "SLOT #0: TEMP #3"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.4 = STRING: "SLOT #0: TEMP #4"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.5 = STRING: "SLOT #0: TEMP #5"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.6 = STRING: "SLOT #0: TEMP #6"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.7 = STRING: " FAN #1"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.8 = STRING: " FAN #2"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.9 = STRING: " FAN #3"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.10 = STRING: " Power Supply #1"
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5.11 = STRING: " Power Supply #2"

Searching index is 7.

snmpwalk -v2c -c xxx vdx01 SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.3.7
SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.3.7 = INTEGER: 4

It is OK.

But in Zabbix 1.8.11 error message is generated:

22053:20120322:175859.311 item [vdx02:fan.1] became not supported: cannot find index [SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5] of the OID [SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.3["ind
22053:20120322:175859.312 item [vdx01:fan.2] became not supported: cannot find index [SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.5] of the OID [SNMPv2-SMI::enterprises.1588.2.1.1.1.1.22.1.3["ind

How to create valid SNMP item with dynamic index in Zabbix 1.8.11?
