Hi Daniel,
First, thanks for the most thorough and well researched support request
we have received to date! This should be a template to all.
Thanks to the work and tests you've done, it seems to me that the Cisco
device / os version you're using supports MAU but not all of the MIBs.
Can you try the latest version from GitHub where I've pushed a small
change ( http://git.io/pgQ7 ) that will hopefully catch these errors
without affecting the rest of the switch polling.
Thanks!
- Barry
