Revert to CTC Communication

You decide to revert CA MIM back to using the CTC communication.

Follow these steps:

1. Use the SET MIM VCFPREFERENCE=CTC command.
   • On GK13:

     @SET MIM VCFPREFERENCE=CTC
     MIM0067I Command SETOPTION 035
     MIM0052I SETOPTION MIM processing complete
     MIM0292I VCF switched to alternate VCF path 183A
     @D PATH
     MIM0067I Command DISPLAY 039

     In the previous display, you can see that GK13 is now using CTC address 183A to GK03.

     In the previous display, you can see that GK62 is now using CTC address 184A to GK03.

No commands are required for GK23 because it was already using CTCs. The command is not needed on the current VCFMASTER(GK03) because it detects the switch from the clients.
