Port
Priority
Path Cost
The switch port: fe01-24, ge25-26.
Range 0 to 240 in steps of 16. Lower number is higher priority.
Enter the path cost or 0 to derive cost from port speed.
Configuring IGMP snooping
When IGMP snooping is enabled, the FortiGate-224B unit monitors multicast
traffic and dynamically configures ports so that multicast packets are sent only to
ports with clients interested in this traffic. This can help control traffic through the
switch.
Go to Switch > Protocols > IGMP Snooping to configure IGMP settings.

on switch-VLANs. See “Configuring a switch VLAN” on

Configuring QoS
Configuring QoS settings
Quality of Service (QoS) settings enable you to prioritize network traffic by type.
Inter-Switch Link (ISL) trunk frames carry IEEE 802.1P Class of Service (CoS)
information. You can use this to set priorities and rate limiting for traffic by type.
FortiGate-224B also supports the use of Layer-3 Differentiated Services Code
Point (DSCP) values to prioritize traffic.
Go to Switch > Qos > Config to configure QoS settings.
