DUP-IPADDR

Default Severity: Minor (MN), Non-Service Affecting (NSA)
Logical Object: NE
The Duplicate IP Address alarm indicates that the alarmed node IP address is already in use within the same
data communications channel (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).

3. In the IP Address field, change the IP address to a unique number.
4. Click Apply.
5. Restart any CTC sessions that are logged into either of the duplicate IP addresses. (For procedures to log
