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

Operating System is Windows Server 2022 for all rows in the table below.

Role	CPU (min)	RAM (min)	Disk (min)	Supports up to:
Agent - SNMP	4 x Cores	8 GB	60 GB	20,000 discovered elements (watches)
Agent - API	4 x Cores	8 GB	60 GB	20,000 discovered elements (watches)
Flow collector	4 x Cores	16 GB	80 GB	Up to 400 Flow sources
Flow collector	4 x Cores	32 GB	80 GB	Up to 800 Flow sources

NB: Supported numbers are based on using SNMP v2 and the default polling period of 3 minutes for SNMP and 5 minutes for API.

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 No.	Direction
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
Data collection	Flow collector	Highlight system	TCP 443	Outbound from customer
Data collection	Customer based poller	Highlight system	TCP 443	Outbound from customer
Configuration	Enterprise servers (pollers)	Highlight system	TCP 443	Outbound from service provider
Configuration	Flow collector	Highlight system	TCP 443	Outbound from customer
Configuration	Customer based poller	Highlight system	TCP 443	Outbound from customer
Management	Highlight network	Enterprise servers (pollers)	TCP 3389 UDP 3389	Inbound to service provider
Controllers	Enterprise server	Extreme WiFi controller	TCP 443	Inbound to service provider

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 No.	Notes
MOS & Precisional testing	Router running test	Target device	UDP 80	Test packets
MOS & Precisional testing	Router running test	Target device	UDP 1967	Test set up
