Hello Zabbix Team,

For security to create this issue we changed the original ip addresses for IP_PROXY and IP_EMC_VNX5500.

We have some problems with one storage device using the Low-level discovery of SNMP OID's.
we use the Low-level discovery of SNMP OID's with a lot of devices and it always works correctly except with one device "EMC_VNX5500"

when the problem is analyzed we find the following mistake in the logs of the server

"SNMP error: (noSuchName) There is no such variable name in this MIB."

but using the snmpwalk and snmpget commands the information is shown

#snmpwalk -v 2c -c public IP_EMC_VNX5500  IF-MIB::ifAdminStatus

IF-MIB::ifAdminStatus.1 = INTEGER: up(1)
IF-MIB::ifAdminStatus.2 = INTEGER: up(1)
IF-MIB::ifAdminStatus.3 = INTEGER: up(1)
IF-MIB::ifAdminStatus.4 = INTEGER: up(1)
IF-MIB::ifAdminStatus.5 = INTEGER: up(1)
IF-MIB::ifAdminStatus.6 = INTEGER: up(1)
IF-MIB::ifAdminStatus.7 = INTEGER: up(1)
IF-MIB::ifAdminStatus.8 = INTEGER: up(1)
: 
:
IF-MIB::ifAdminStatus.71 = INTEGER: up(1)

(I truncated the output to avoid overflow of information)

#snmpget -v 2c -c public IP_EMC_VNX5500 IF-MIB::ifAdminStatus.8  

IF-MIB::ifAdminStatus.8 = INTEGER: up(1)

we ran a tcpdump to find out the problem and we found "noSuchName@22 interfaces.ifTable.ifEntry.ifOutErrors.58"

(attached output in the file)

thanks for your time.
