How should I deal with these SNMP mib file parsing errors? -

i trying use mib files supplied cisco make sense info obtainend polling switch via snmp. it's sg300-52p, files can found here.

after placed files in 1 of netsnmp's default mib directories, there multiple errors when tried decode 1 of description numeric value verify mib files work. thought resolving issues, numerous, decided try , simplest of these files work netsnmp. placed snmpv2-smi file in 1 of netsnmp's default mib directories (because came in errors , short file no dependencies; i've appended content easy reference) , ran following command:

snmptranslate -m snmpv2-smi zerodotzero 

however, returns following 2 erros:

expected last-updated (smi): @ line 35 in /home/buildmanager/.snmp/mibs/snmpv2-smi.my zerodotzero: unknown object identifier (sub-id not found: (top) -> zerodotzero) 

after googling , guessing, went ahead , checked file online mib file validator here, objected that

line 34: 2   `smi' should start lower case letter 1   syntax error, unexpected module_identity, expecting object 

i have no idea make of these messages, googling them revealed nothing make sense of. mean file has errors? it's file officially supplied cisco, , it's basic - can't imagine case. i've made sure there no interfering snmpv2-smi anywhere else on system, i'm sure file netsnmp using. suspect there here did not understand snmp , these mib files in general, please point me @ right direction or tell me , how answers. thanks!

contents of snmpv2-smi:

that snmpv2-smi file quoted has been modified original/standard use special syntax specific smic compiler (those "smi" keywords "smi counter32"), per comments @ beginning:

--      converted smic format. 

this broken syntax (no longer valid smiv1 or smiv2) according other parser/compiler, hence errors. should add mibs net-snmp need not provided (as snmpv2-smi should be), , should use standard syntax, not compiler-specific extensions (unless implemented in comments).
