Hello,
I have the same problem.

When I try snmpwalk from console, it works fine:
snmpwalk -v2c -cpublic 192.168.250.2 ifInOctets
...
IF-MIB::ifInOctets.234938496 = Counter32: 0
IF-MIB::ifInOctets.234938560 = Counter32: 0
IF-MIB::ifInOctets.4194304000 = Counter32: 2879295579
IF-MIB::ifInOctets.4194304256 = Counter32: 1700152257
...

but snmpget of single value is not working:
snmpget -v2c -cpublic 192.168.250.2 ifInOctets.4194304000
ifInOctets.4194304000: Unknown Object Identifier (Index out of range: 4194304000 (ifIndex))

Execution of snmpwalk for IfIndexes returns following values:
snmpwalk -v2c -cpublic 192.168.250.2 ifIndex
...
IF-MIB::ifIndex.234938496 = INTEGER: 234938496
IF-MIB::ifIndex.234938560 = INTEGER: 234938560
IF-MIB::ifIndex.4194304000 = INTEGER: -100663296
IF-MIB::ifIndex.4194304256 = INTEGER: -100663040
...

I'm using Zabbix 2.2.4 and NET-SNMP v. 5.5-49.

The device is Huawei MA5603T.

Hello, Petr Petrovic. We've resolve this problem with our chassis. It isn't very good, but its working. If you would like to, we can have some conversation via email ( my email is [email protected], I'd like to speak about huawei devices, best practices, and some other stuff).
The problem is in IF-MIB oid tree, and the way NET-SNMP uses it. Its not zabbix problem. I found resolution in external check. I've made some template, which is based on "SNMP Interfaces Template", but I'm using external script, instead of SNMPGET. For example, if you use:

snmpget -v 2c -c public ipaddress ifInOctets.4194304000, u'll get
ifInOctets.4194304000: Unknown Object Identifier (Index out of range: 4194304000 (ifIndex))

but if you'll use:
snmpget -v 2c -c public -Ir ipaddress ifInOctets.4194304000, u'll get
IF-MIB::ifInOctets.4194304000 = Counter32: 2232987660

Option "-Ir" stands for
-I INOPTS Toggle various defaults controlling input parsing:
r: do not check values for range/type legality
(its is from net-snmp help)

Hope, it will help you. And I'd really like to have conversation with you. Good luck!

Hello. I have same problem with Huawei S5700, S5710 and S9703 swithes.
On version 2.0.2 zabbix can get OID hwMemoryDevFree.0.0.0 ( also hwMemoryDevSize.0.0.0, hwCpuDevDuty.0.0.0) , but on version 2.2.6 this OID is 'Not supported'
Could you share your solution for similar problems?

Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-7595
version 2.2

Fix for OID higher than MAX_INT to be accepted.
noRangeCheck yes disables the validation of varbind values against the MIB definition for the relevant OID. This is equivalent to the -Ir option.

Tested SNMP OID: "ifInOctets.4194304000"

Before fix:
Error not supported.

After fix:
Works.

(1) In zbx_snmp_print_oid() there is a check for netsnmp_ds_set_boolean() return code. In modified zbx_snmp_open_session() return code from netsnmp_ds_set_boolean() is not checked. I would recommend to add the check.
