Introduction

A distributed TruView environment always contains a TVC. The TVC is the window to your data and it can be accompanied by a TVF, a TVP or both. Please note that a TVP (TruView Packet) acts a true packet collector, while a TVF (TruView Flow) is equipped with a GUI and is capable of showing NetFlow results. However this GUI is available, it is depriciated and shouldn't be used anymore.

Solution

TVC inbound ports

destination service role
tcp/443 https user portal
tcp/22 ssh management cli

TVC outbound ports

destination service role
udp/53 dns domain name service
tcp/389 ldap remote authentication
tcp/636 sldap secure remote authentication
udp/123 ntp network time synchronization
tcp/25 smtp mailrelay (email external notification)
udp/161 snmp polling device health status of exporter

TVF inbound ports

destination service role
tcp/443 https user portal (depreciated)
tcp/22 ssh management cli
udp/2055,udp/6343* netflow receiving netflow packets from exporter

(*) inbound netflow services are depending on the configuration of the exporting device.

TVF outbound ports

destination service role
udp/53 dns domain name service
udp/123 ntp network time synchronization
udp/161 snmp polling interface utilization of exporter

TVP inbound ports

destination service role
tcp/22 ssh management cli

TVP outbound ports

destination service role
udp/53 dns domain name service
udp/123 ntp network time synchronization

Distributed TruView internal communication ports

destination service role
tcp/443 https TVC -> TVF/TVP
tcp/443 https TVF/TVP -> TVC
