Scenario: A Citrix Administrator manages an environment that has a Citrix ADC high availability (HA) pair running on two MPX appliances. The administrator notices that the state of the Secondary Citrix ADC is
'Unknown' and moves the Secondary Citrix ADC to a new switch as a result. Also, the administrator captured a packet trace on both Citrix ADCs. Both sent traffic on secure port 3009 and were routing back and forth to each other.
What is causing the Secondary state to be 'Unknown'?
