Configure QoS with managed FortiSwitches (373581)

Quality of Service (QoS) provides the ability to set particular priorities for different applications, users, or data flows. NOTE: FortiGate does not support QoS for hard or soft switch ports.

To configure the QoS for managed FortiSwitches:

  1. Configure a Dot1p map.

config switch-controller qos dot1p-map edit <Dot1p map name> set description <text> set priority-0 <queue number> set priority-1 <queue number> set priority-2 <queue number> set priority-3 <queue number> set priority-4 <queue number> set priority-5 <queue number> set priority-6 <queue number> set priority-7 <queue number>

next

end

  1. Configure a DSCP map.

config switch-controller qos ip-dscp-map edit <DSCP map name> set description <text> configure map <map_name> edit <entry name> set cos-queue <COS queue number>

set diffserv {CS0 | CS1 | AF11 | AF12 | AF13 | CS2 | AF21 | AF22 | AF23 | CS3 | AF31 | AF32 | AF33 | CS4 | AF41 | AF42 | AF43 | CS5 | EF |

CS6 | CS7} set ip-precedence {network-control | internetwork-control | critic-ecp

| flashoverride | flash | immediate | priority | routine} set value <DSCP raw value>

next

end end

  1. Configure the egress QoS policy.

config switch-controller qos queue-policy edit <QoS egress policy name> set schedule {strict | round-robin | weighted}

config cos-queue edit [queue-<number>] set description <text> set min-rate <rate in kbps> set max-rate <rate in kbps>

set drop-policy {taildrop | random-early-detection} set weight <weight value>

next

end

next

end

  1. Configure the overall policy that will be applied to the switch ports.

config switch-controller qos qos-policy edit <QoS egress policy name> set default-cos <default CoS value 0-7> set trust-dot1p-map <Dot1p map name> set trust-ip-dscp-map <DSCP map name> set queue-policy <queue policy name>

next

end

  1. Configure each switch port.

config switch-controller managed-switch edit <switch-id> config ports edit <port> set qos-policy <CoS policy>

next

end

next end
