Description

This article describes conditions that change Port Connection State to Multiple Hosts.

Scope

FortiNAC.

Solution

The Connection State changes to Multiple Hosts when more than one MAC address is detected off a managed switch port. This includes IP Phones. The threshold used to define the Multiple Hosts Connection State cannot be changed.

Example:

An IP Phone connects to a port. Port shows the IP Phone icon in Port View until a computer connects behind the IP Phone. The icon changes to a cloud (indicating Multiple Hosts).

Once the number of MAC addresses on the port exceeds the System Defined Uplink count, the Connection State changes to Threshold Uplink.

System Defined Uplink Count

When the number of MAC addresses on a port exceeds this value the port is changed to an uplink. Setting this value to a higher number can help to indicate Multi-Access points.

Default setting = 20

For example, setting this value to 7 changes the port to an uplink if a minihub with 8 ports is connected on the port.

See Port properties.
