Description

Recent testing against Accelerator Division devices has shown that the isBlocked()
function in the BRIDGEMibBlocker.py module is unreliable. The isBlocked() test
reads the row indexed by MAC from the dot1dStaticTable and compares the result
to the permanent/temporary block value. Specifically, a Cisco C3500XL has
demonstrated the ability to return isBlocked() == True for any random MAC.

A possible fix may require isBlocked() to access a device specific flag which
indicates if the value for dot1dStaticStatus should be trusted.

  • Status changed from New to Rejected

Tim Zingelman reports that they no longer have any Cisco C3500XL network devices. This looks like a moot bug.
