Solution Prerequisites

Hardware Sizing

The following lists the machine specifications for up to 100 concurrent agents deployment.

vCPU	vRAM	vDisk
2 cores	8 GB	1x100 GB

To support HA, the same specifications would be doubled for the two machines for a redundant deployment.

To get machine specifications for a larger agent volume and/or with other ExpertFlow products in a co-resident deployment, please check here.

Software Requirements

Port Utilization

The following ports should remain open on the Firewall. The local security policy and any antivirus should also allow open communication on the following ports.

Type	Source Host	Source Port	Destination Host	Destination Port
HTTP	Enterprise web user	any	CIM	80
HTTPS	Dashboards & Wallboards server	any	CIM	443
TCP	Enterprise web user		CIM	9242

System Access Requirements

Deployment Privileges

Administrative privileges (root) on the machine are required to follow the deployment steps.

Internet access must also be available on the Wallboard machine with inbound connections on port 9242 enabled.

Time Synchronization Requirements

If the system dates and times are not synchronized, the system can produce unpredictable results. Therefore, the EF applications and Cisco Contact Center should have their time zone and date/time properly configured, according to the geographic region and must be synchronized.

To configure the time zone, please see the instructions from the hardware or software manufacturer of the NTP server. The application servers should be synchronized. This synchronization should be maintained continuously and validated on a regular basis. For security reasons, the Network Time Protocol (NTP) V 4.1+ is recommended.
