With Redundant Network System Type, secondary IP address not used when set to active


Applies To:

PAC Control Professional

Versions Affected:

R10.0a to R10.2b

Resolved In Version:

R10.2c


Symptoms:

For a PAC Control Engine configured with a System Type of Redundant Networks, if you set the Secondary IP Address as the active IP address (in PAC Control, right-click the control engine, then select "Use Secondary IP Address"), when in Debug mode, you could see any of the following behavior:

  • In PAC Control, select Control Engine > Inspect. The top of the inspect window shows that the control engine's primary IP address is being inspected, not the secondary IP address.
  • If you unplug the Ethernet cable from the Ethernet 1 port, PAC Control displays a timeout message.

Resolution:
