We have updated the MikroTik MIB file to be compatible with the validator (http://www.simpleweb.org/ietf/mibs/validate/)
This change also requires that we change one OID:
"Wireless Registration Table Entry Count" will change
From: 1.3.6.1.4.1.14988.1.1.1.2.2.0
To: 1.3.6.1.4.1.14988.1.1.1.4.0
In next RouterOS releases. Please update your program settings. This will be included in the Changelog as well.
New MIB is attached, and also available here: http://mikrotik.com/download/Mikrotik.mib
