Environment

DX NetOps Spectrum all currently supported releases

Cause

Check if a firewall is preventing the communication between the Primary SpectroSERVER processd and rcpd to the Secondary SpectroSERVER processd and rcpd. 

Also if running on OpenStack, verify in the OpenStack configuration that there is no typo in the IPv4 and/or IPv6 address.

Resolution

Ensure to open the following ports from the Primary SpectroSERVER to the Secondary SpectroSERVER:

65259

61904

51966

The Linux ncat command can be used to test connectivity:

nc <IP_ADDRESS> <PORT>

For example : nc 192.168.0.1 51966

Confirm both ways is successful.
