12.3 QoS Configuration
12.3.1 Configuration Guidelines
Table 12-1 General Settings of QoS
| Operation | Command |
| Configure QoS interface | qos interface <interface_name> [direction] [bandwidth] |
| Define QoS queue | qos queue root <queue_name> <interface_name> [direction] [bandwidth]
[priority] [borrow] [default] qos queue sub <queue_name> <parent_queue> [bandwidth] [priority] [borrow] [default] |
| Define QoS filter rules | qos filter <filter_name> <queue_name> < src_addr> <smask> <sport> <dst_addr> <dmask> <dport> <proto> [priority] |
| Enable QoS | qos enable <interface_name> [direction] |
12.3.2 Configuration Example via CLI
- Step 1 Define QoS interfaces
FortiBalancer(config)#qos interface port1 OUT 5Mb
FortiBalancer(config)#qos interface port1 IN 5Mb
- Step 2 Define outgoing QoS queues
FortiBalancer(config)#qos queue root qr_oall port1 OUT 5Mb 3
FortiBalancer(config)#qos queue sub qs_ossh qr_oall 2Mb 3 UNBORROW NONDEFAULT
FortiBalancer(config)#qos queue sub qs_oftp qr_oall 512kb 2 UNBORROW NONDEFAULT FortiBalancer(config)#qos queue sub qs_odeflt qr_oall 8kb 3 UNBORROW DEFAULT
Default queue is for all the other packets which cannot hit any defined queues.
- Step 3 Define incoming QoS queues
FortiBalancer(config)#qos queue root qr_iall port1 IN 5Mb 3
FortiBalancer(config)#qos queue sub qs_issh qr_iall 2Mb 3 BORROW NONDEFAULT
FortiBalancer(config)#qos queue sub qs_iftp qr_iall 2Mb 2 BORROW NONDEFAULT
FortiBalancer(config)#qos queue sub qs_ideflt qr_iall 8kb 3 BORROW DEFAULT
- Step 4 Define QoS filter rules
FortiBalancer(config)#qos filter fltr_ftp_o qs_oftp 0.0.0.0 0.0.0.0 0 10.3.54.40 255.255.255.255
0 tcp 2
FortiBalancer(config)#qos filter fltr_ftp_i qs_iftp 10.3.54.40 255.255.255.255 0 0.0.0.0 0.0.0.0 0 tcp 2
FortiBalancer(config)#qos filter fltr_ssh_o qs_ossh 0.0.0.0 0.0.0.0 22 0.0.0.0 0.0.0.0 0 tcp 3
FortiBalancer(config)#qos filter fltr_ssh_i qs_issh 0.0.0.0 0.0.0.0 0 0.0.0.0 0.0.0.0 22 tcp 3
Ø Step 5 Enable QoS
FortiBalancer(config)#qos enable port1 OUT
FortiBalancer(config)#qos enable port1 IN
