Technical Tip: Traffic shaper and bandwidth unit display

Description

This article describes bandwidth unit differences.

Solution

1. MAX bandwidth unit is configured on mbps default:

config firewall shaper traffic-shaper
    edit profile-Melb
    (profile-Melb)get
    name : MS-Updates-Melb
    guaranteed-bandwidth: 0
    maximum-bandwidth : 30
    bandwidth-unit : mbps                                   <----- mbit.
    priority : medium
    per-policy : enable
    diffserv : disable

Note: to change the bandwidth-unit, follow the process below.

The 'bandwidth-unit' parameter cannot be set for a FortiGate running on 32-bit processors.

To check if FortiGate is using a 32-bit or 64-bit processor:

Technical Tip: Check whether FortiGate is running 32-bit or 64-bit firmware.

config firewall shaper traffic-shaper
    edit profile-Melb
        set  bandwidth-unit
        kbps    Kilobits per second.
        mbps    Megabits per second.
        gbps    Gigabits per second.

2. However, when the diagnose command runs to check the shaper traffic-shaper list, see the unit in Kbytes.

diagnose firewall shaper traffic-shaper list

name MS-Updates-Melb
maximum-bandwidth 3840 KB/sec                               <----- Kbytes.
guaranteed-bandwidth 0 KB/sec
current-bandwidth 0 B/sec
priority 3
tos ff
packets dropped 0
bytes dropped 0

As a result, the configuration unit is in mbit.
