Issue Description
Customer use version ME60 V100R006C05SPC600. NMS monitor a lot of parameters using SNMP. One of parameter is query ME60 to know which interface belong to which Eith-trunk. OID value that used for it is 1.3.6.1.4.1.2011.5.25.41.1.4.1.1.2, but when try query it, receive error:

snmpwalk -c community_name -v2c  ip_address 1.3.6.1.4.1.2011.5.25.41.1.4.1.1.2
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.738197889 = INTEGER: 1
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.201326977 = INTEGER: 1
Error: OID not increasing: SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.738197889 >= SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.201326977



Alarm Information
null

Handling Process
This is will be fixed at new version V6R3C05 (planed release April 2012). As workaround use snmpwalk utility with key "-C -c". After key is applyed output is normal:

# snmpwalk -c community_name -C c -v2c ip_address 1.3.6.1.4.1.2011.5.25.41.1.4.1.1.2
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.738197889 = INTEGER: 1
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.201326977 = INTEGER: 1
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.0.469762433 = INTEGER: 1
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.1.268435841 = INTEGER: 1
SNMPv2-SMI::enterprises.2011.5.25.41.1.4.1.1.2.1.335544705 = INTEGER: 1
Root Cause
ME60 don't follow strictly to rfc standard.


Suggestions
According description of snmpwalk utility this error indicate that SNMP database at device don't keep these parameters as ordered list, so utility can not interact with ME60 at standard manner.
There is RFC 2578 that require place parameters as order list:
3.5. OBJECT IDENTIFIER values
An OBJECT IDENTIFIER value is an ordered list of non-negative
numbers. For the SMIv2, each number in the list is referred to as a
sub-identifier, there are at most 128 sub-identifiers in a value, and
each sub-identifier has a maximum value of 2^32-1 (4294967295
decimal).
