libsmi/smidump 0.4.8 problem: SYSAPPL-MIB::sysApplPastRunMaxRows SYNTAX Upper Bound
by Jens Engel 18 Mar '11

18 Mar '11

smidump 0.4.8 (up to rev13631 and maybe never) have a problem with the following SMI construct: -- FROM libsmi distributed SYSAPPL-MIB: sysApplPastRunMaxRows OBJECT-TYPE SYNTAX Unsigned32 (0..'ffffffff'h) ... NOTE: 0xFFFFFFFF = 2^32-1 = 4 294 967 295 when you try to convert the provided MIB via: smidump --format=smiv2 SYSAPPL-MIB ... you get the following output for libsmi 0.4.7 and 0.4.8. NOTE: Upper syntax bound is wrong in both cases. === modified file 'IETF/mibs/SYSAPPL-MIB.mib' --- IETF/mibs/SYSAPPL-MIB.mib 2009-03-28 19:03:48 +0000 +++ IETF/mibs/SYSAPPL-MIB.mib 2009-05-04 16:57:29 +0000 @@ -1038,7 +1038,7 @@ ::= { sysApplElmtPastRunEntry 11 } sysApplPastRunMaxRows OBJECT-TYPE - SYNTAX Unsigned32 (0..1134880) -- smidump 0.4.7 output + SYNTAX Unsigned32 (0..1134864) -- smidump 0.4.8 rev13631 (post-release) NOTE: Output of SYNTAX upper bound varies. WEIRD: The conversion to format=python leads to the correct result. Without looking at the source code, I assume that the hex-string to integer conversion has a problem.

validating mib implementation
by Joao Ferreira gmail 14 Jun '10

Hello all, I'm not sure if this could be considered off-topic. I'm sorry if it is... I've been using smilint to check my new MIB as I add content to it. But I'm now searching for some tool that actually allows me to validate SNMP agents that are supposed to implement that MIB... My question is: how do I make sure that a given device correctly implements my MIB ? how do I get warnings or errors saying that a given SNMP agent deviates more or less from the MIB definitions ? Thanks Joao
