smidump --format=smiv2 output contains some errors in compliance SYNTAX/WRITE-SYNTAX clauses.
by Jens Engel 06 Jun '13

Hello, I just stumbled over the following problem in libsmi 0.4.8 and development trunk-tip rev34557 (as of today). The problem resides in the SYNTAX/WRITE-SYNTAX clauses in COMPLIANCE statements. Instead of a "type" the invalid term "(null)" is present. AFFECTED-MIBS (at least): - BRIDGE-MIB - SNMP-VIEW-BASED-ACM-MIB - ... => grep "(null)" *-MIB EXAMPLE: smidump --format=smiv2 BRIDGE-MIB ... OBJECT dot1dStpPriority SYNTAX (null) (0 | 4096 | 8192 | 12288 | 16384 | 20480 | 24576 | 28672 | 32768 | 36864 | 40960 | 45056 | 49152 | 53248 | 57344 | 61440) ... OBJECT dot1dStpPortPriority SYNTAX (null) (0 | 16 | 32 | 48 | 64 | 80 | 96 | 112 | 128 | 144 | 160 | 176 | 192 | 208 | 224 | 240) BUT: Original BRIDGE-MIB that is distributed w/ libsmi contains: OBJECT dot1dStpPriority SYNTAX Integer32 (0 | 4096 | 8192 | 12288 | 16384 | 20480 | 24576 | 28672 | 32768 | 36864 | 40960 | 45056 | 49152 | 53248 | 57344 | 61440) ... OBJECT dot1dStpPortPriority SYNTAX Integer32 (0 | 16 | 32 | 48 | 64 | 80 | 96 | 112 | 128 | 144 | 160 | 176 | 192 | 208 | 224 | 240) smidump --format=smiv2 SNMP-VIEW-BASED-ACM-MIB ... OBJECT vacmViewTreeFamilyMask WRITE-SYNTAX (null) (SIZE(0)) ... SHOULD-BE (as in original MIB distributed with libsmi): ... OBJECT vacmViewTreeFamilyMask WRITE-SYNTAX OCTET STRING (SIZE(0)) I assume that smidump does not have the info (only a NULL pointer) and just dumps it as textual info. NOTE: "smidiff <ORIGINAL-MIB> <SMIDUMPED-MIB>" does not seem to show a difference (except warnings, ...). Ciao, Jens

smiGetFirstRevision() does not return most recent revision
by Jonathan Walker 21 Mar '13

Hello, I have a MIB that currently has 70 revisions (IANAifType-MIB), and yet smiGetFirstRevision() is returning the 31st revision, and not the first. I'm using a DLL that I compiled myself, although I did not make any changes to the code base. LibSMI version 0.4.5. Please let me know if you require more information. Thank you, Jonathan ________________________________ This e-mail and any attachments are confidential.

Smidump python output issues
by Tuure Laurinolli 18 Mar '13

Hi, It appears that smidump turns the variable list defined in a NOTIFICATION-TYPE into a dict. This seems fine on the surface, but does not preserve ordering of the variables. As per section 8.1 of RFC 2578, the sequence of variables should be ordered. Is there a known workaround for this?
