Server Specifications

Overview

All Highlight software runs on an Agent platform, which has functional modules to carry out specific tasks. The specification of the server required is dependent on the role(s) they have. The higher specification should always be adopted.

This page also details network access required, for the servers and other Highlight functions.

Server specification

Role	Operating System	CPU	RAM	Disk	Supports up to:	Notes
Enterprise	Windows Server 2022	4 x Cores	8 GB	60 GB	10,000 devices	Poller function (SNMP v2)
Enterprise		4 x Cores	16 GB	60 GB	10,000 devices + SD-WAN	Poller function (SNMP v2)
Enterprise		4 x Cores	16 GB	60 GB	5,000 devices	Poller function (SNMP v3)
Flow collector		4 x Cores	16 GB	80 GB	Up to 200 Flow sources	Dependant on the number of distinct flows generated by each source
Flow collector		4 x Cores	32 GB	80 GB	Up to 400 Flow sources

Notes

The Disk space values given above take into account the space required for Windows (50GB)
It is recommended that Poller Enterprise servers are geographically separated for optimum resilience
No Windows Roles/Features are required, although Windows Firewall is recommended
The servers do not need to be part of a Domain
.NET 4.8 is required to be installed
Time to be configured from an NTP server, to ensure server keeps in time sync with Highlight
Wireshark installation (the Tshark module as a minumum) is recommended for troubleshooting purposes

Network access requirements

Function	Source	Destination	Port number	Direction	Notes
Polling	Enterprise servers (pollers)	Routers/switches	UDP 161	Inbound to customer
Polling	Customer based pollers	Routers/switches	UDP 161	Inbound within customer
Flow	Router monitored for flow	Flow collector	UDP 9996	Outbound to flow collector
Data collection	Enterprise servers (pollers)	Highlight system	TCP 443	Outbound from service provider
	Flow collector			Outbound from customer
	Customer based poller			Outbound from customer
Configuration	Enterprise servers (pollers)	Highlight system	TCP 443	Outbound from service provider
	Flow collector			Outbound from customer
	Customer based poller			Outbound from customer
Management	Highlight network	Enterprise servers (pollers)	TCP 3389 UDP 3389	Inbound to service provider
Controllers	Enterprise server	Aerohive controller	TCP 443	Inbound to service provider	Aerohive WiFi

Note: We strongly recommend that Highlight agents are configured to synchronise their clock with a reliable time source, which may require additional network access. Documentation for the Windows Time service is available from Microsoft’s Website

Non-server network access

Function	Source	Destination	Port number	Notes
MOS and Precision testing	Router running test	Target device	UDP 80	Test packets
MOS and Precision testing	Router running test	Target device	UDP 1967	Test set up
