Server Configuration - MikroTik RouterOS v2.9 Reference Manual

to analyze its behavior. Statistics for throughput are calculated using the entire size of the TCP
packet. As acknowledgments are an internal working of TCP, their size and usage of the link are not
included in the throughput statistics. Therefore this statistic is not as reliable as the UDP statistic
when estimating throughput.
The UDP tester sends 110% or more packets than currently reported as received on the other side of
the link. To see the maximum throughput of a link, the packet size should be set for the maximum
MTU allowed by the links which is usually 1500 bytes. There is no acknowledgment required by
UDP; this implementation means that the closest approximation of the throughput can be seen.
Usage Notes
Caution! Bandwidth Test uses all available bandwidth (by default) and may impact network
usability.
Bandwidth Test uses much resources. If you want to test real throughput of a router, you should run
bandwidth test through it not from or to it. To do this you need at least 3 routers connected in chain:
the Bandwidth Server, the given router and the Bandwidth Client:
Note that if you use UDP protocol then Bandwidth Test counts IP header+UDP header+UDP data.
In case if you use TCP then Bandwidth Test counts only TCP data (TCP header and IP header are
not included).

Server Configuration

Home menu level: /tool bandwidth-server
Property Description
allocate-udp-ports-from - allocate UDP ports from
authenticate ( yes | no ; default: yes ) - communicate only with authenticated (by valid username
and password) clients
enable ( yes | no ; default: no ) - enable client connections for bandwidth test
max-sessions - maximal number of bandwidth-test clients
Notes
The list of current connections can be obtained in session submenu
Example
Bandwidth Server:
[admin@MikroTik] tool bandwidth-server> print
authenticate: yes
allocate-udp-ports-from: 2000
max-sessions: 10
[admin@MikroTik] tool>
Active sessions:
