2.6.37 DUP-IPADDR

2.6.37 DUP-IPADDR
The Duplicate IP Address alarm indicates that the alarmed node IP address is already in use within the
same DCC area. When this happens, CTC no longer reliably connects to either node. Depending on how
the packets are routed, CTC could connect to either node (having the same IP address). If CTC has
connected to both nodes before they shared the same address, it has two distinct NodeModel instances
(keyed by the node ID portion of the MAC address).

Clear the DUP-IPADDR Alarm

Isolate the alarmed node from the other node having the same address by completing the following steps:
Step 1
a.

Step 3
Click Apply.
Step 4

Step 5
instructions to log in or log out, refer to the "Set Up PC and Log Into the GUI" chapter in the
