Old Updating MIBs Process

Some git tips

• On MacOS and Linux: git config --global core.autocrlf input
• Always push new tags with commits: git config --global push.followTags true
• Short diff summary: git diff --shortstat

Check out a Github pull request into a branch using the commands in this gist.

Old Style

• Having indexes helps with verifying the MIB collection using the old chk_* scripts from Max
• Always run snmptranslate -Tt on the whole collection before changing anything, and closely inspect the diffs
• Do a lot of intermediate snmptranslate sequences as well, to spot errors or incompatible MIB updates

Remove all files in /var/net-snmp/mib_indexes/, run the command snmptranslate -Tt | sed -re 's/ tc=[0-9]+//g' and redirect its output to a file, fixing items in STDERR until it's empty.

The STDOUT output is the one to compare between "starting point" and "end point" of changes.

After that snmptranslate routine, run the regen_indexes.pl script, then the mkindex script, then the chk_* scripts. Fix issues, rinse, repeat.

So something like...

1. run snmptranslate -Tt and save STDOUT
2. run snmptranslate -Tt inspecting errors (rinse, repeat....)
3. run snmptranslate and compare to (1)
4. run regen indexes to copy system indexes
5. run mkindex to gather indexes
6. run chk_dups
7. run chk_mibs (should be error free?)
