RE: [libsmi] specifying OID value
HI David, My intention was to specify an oid value for the mib variable 'test-var9': <oid-value for testObjectIdentity>.1 . For example, if testObjectIdentity's oid-value is x.x.x, where x is a non-negative integer then test-var9's oid-value should be x.x.x.1 . But it seems test-var9 is given an oid-value of 1.1. Am i right? ____________________________________________________________________________ ___________ -Vinoth iDEN OMC Software, Motorola

HI,
Frank - it is perfectly legal to specify "{ testObjectIdentity(1) 1 }" for the OID value. And the result is the OID value of { 1 1 } Of course, this is probably not the desired result.

The OID value of testObjectIdentity is already defined by the
OBJECT-IDENTITY
construct. The "(1)" in "{ testObjectIdentity(1) 1 }" does
not make sense.
What meaning would you expect? A redundant repitition of the fact that the last sub-oid of testObjectIdentity is "1"? Or a redefinition of testObjectIdentity to the one-digit OID value "1" and the defintion of test-var9 to "1.1"?
Your change to "{ testObjectIdentity 1 }" is (syntactically)
correct and
defines the value of test-var9 to "testObjectIdentity.1" ==
"cMIB.1.1".

HI,
When you say
test-var9 OBJECT-TYPE ... ::= { testObjectIdentity(1) 1 } the OID value is { 1 1 }
When you say
test-var9 OBJECT-TYPE ... ::= { testObjectIdentity 1 } the OID value is { <the_oid_value_of_testObjectIdentity> 1 }
This is "standard ASN.1".
