Description:  

CA Spectrum asserting a "BAD LINK DETECTED" alarm on virtual interface when the associated physical interface is in an admin/oper down status

ROOT CAUSE: Interface relationships between virtual and physical interface models are not being considered by Spectrum Fault Isolation and Root Cause analysis.

Solution:

The Spectrum_09.04.00.PTF_9.4.102 patch addresses this issue for CA Spectrum release 9.4.1:

Symptom: 

When the interface has admin down status and sub interface has critical alarm then the alarm on the sub interface is shown critical instead of suppressed.

Resolution: 

When the interface is in admin down status and sub interface has critical alarm then  alarm on sub interface will be suppressed.

(329803, 21916952-1)

This fix is not included in 9.4.2.

This is tentatively scheduled to be resolved in CA Spectrum 10.0
