Technical Tip: How to set a scheduled speed test for a SD-WAN Network Monitor

rvijayaraj · ‎05-31-2021

Description
This article describes how to set a scheduled speed test for the SD-WAN Network Monitor.

Solution
Running a test will automatically update the interface measured-upstream-bandwidth and measured-downstream-bandwidth fields.
These fields do not impact the interface inbound bandwidth, outbound bandwidth, estimated upstream bandwidth or estimated downstream bandwidth settings.

While running a speed test, it is possible to bypass the bandwidth limit set on the interface temporarily and configure maximum and minimum bandwidth limits.

# config system speed-test-schedule
    edit <interface>
        set schedules <schedule> ...
        set update-inbandwidth enable {enable | disable}
        set update-outbandwidth enable {enable | disable}
        set update-inbandwidth-maximum <integer>
        set update-inbandwidth-minimum <integer>
        set update-outbandwidth-maximum <integer>
        set update-outbandwidth-minimum <integer>
    next
end

update-inbandwidth                     <----- Enable/disable bypassing interface's inbound bandwidth setting.
update-outbandwidth                  <----- Enable/disable bypassing interface's outbound bandwidth setting.
update-inbandwidth-maximum         <----- Maximum downloading bandwidth (kbps) to be used in a speed test.
update-inbandwidth-minimum         <----- Minimum downloading bandwidth (kbps) to be considered effective.
update-outbandwidth-maximum     <----- Maximum uploading bandwidth (kbps) to be used in a speed test.
update-outbandwidth-minimum       <----- Minimum uploading bandwidth (kbps) to be considered effective.

Setting up a speed test schedule on port1 at 9:13 PM and another at 5:00PM.

1) Configure the recurring schedules.

# config firewall schedule recurring
    edit "At-9PM"
        set start 09:13
        set end 09:14
        set day monday tuesday wednesday thursday friday
    next
    edit "At-5PM"
        set start 17:00
        set end 18:00
        set day monday tuesday wednesday thursday friday
    next
end

Configure the speed test schedule.

# config system speed-test-schedule
    edit "port1"
        set schedules "At-9PM" "At-5PM"
        set update-inbandwidth enable
        set update-outbandwidth enable
        set update-inbandwidth-maximum 60000
        set update-inbandwidth-minimum 10000
        set update-outbandwidth-maximum 50000
        set update-outbandwidth-minimum 10000
    next
end

View the speed test results.

# config system interface
    edit port1

            measured-downstream-bandwidth: 48862
