This read-only TruthValue reports whether a dual-active (split-brain) condition has been detected on the peer device, true meaning Dual Active is detected and false meaning it is not. Administrators treat this as a critical alarm indicator, since a true value means both vPC peer switches may be independently forwarding traffic as if each were the sole active switch, which can cause serious network loops or forwarding inconsistencies. For example, this object reporting true(1) would require immediate admin attention to isolate which switch should remain active and restore single-active forwarding.
