Communication security settings
This section describes the communication security settings that enable you to establish secure communication channels
between metro node components, as well as metro node components and external systems.
Topics:
• IP WAN COM
IP WAN COM
A metro node Metro system does not support native encryption over an IP WAN-COM link. It is recommended that you deploy
an external encryption solution such as IPSec to achieve data confidentiality and end point authentication over IP WAN COM
links between clusters.
Th metro node uses the TCP protocol for its IP WAN-COM communications. Configure TCP ports on the firewall for IP
WAN-COM communications. If the firewall type is filter and not proxy, you must open the following firewall ports:
● TCP ports
○ Port 61484
○ Port 61483
○ Port 61482
○ Ports 32768 to 61000
