Use a bond as bridge port

[Maher Khalil]

Hello
I created bon for 2 uplinks to get double speed of internet but I am getting speed of 1 link only.
switch set for link aggregation LACP
Can any one tell me what is wrong?
=================================================================================> settings (replace bridge IP with my IPs)
auto lo
iface lo inet loopback
iface eno1 inet manual

iface eno2 inet manual
auto bond0
iface bond0 inet manual
bond-slaves eno1 eno2
bond-miimon 100
bond-mode 802.3ad
bond-xmit-hash-policy layer2+3

auto vmbr0
iface vmbr0 inet static
address 10.10.10.2/24
gateway 10.10.10.1
bridge-ports bond0
bridge-stp off
bridge-fd 0
=================================================================================================>

Your expectation is wrong ;-)

A bond doesn´t give you double the speed, it gives you two "lanes" with the same (max) speed (with redundancy/failover). Similar to a highway an extra lane doesn´t mean there is a higher speed (for a single car) but you can handle double the amount of cars in the same time.

So, is there any way to double the speed since I have 4 ports on the server and I want to double the speed?

For more speed you can use Balance-rr mode.

auto bond0
iface bond0 inet manual
        bond-slaves eno1 eno2
        bond-miimon 100
        bond-mode balance-rr

auto vmbr0
iface vmbr0 inet static
        hwaddress xx:xx:xx:xx:xx:xx
        address 192.168.1.150/24
        netmask 255.255.255.0
        gateway 192.168.1.1
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0

In this case do I need to remove LACP FROM SWITCH?

 

[spirit]

with lacp, 1 tcp connection or udp stream, always only use 1 link.

multiple connections are balanced across the links, with the hash policy. (layer3+4 = ip src/ip dest/port src/port dest)

LACP does give you more speed overall, but there is the rule that one session must always go through only one link.

A session is defined by the Hash policy you configure in the bond settings. In your example it is set to bond-xmit-hash-policy layer2+3, so sessions are defined by MAC adresses (layer2) and IP adresses (layer3).

This means that packets from the same Source-MAC/Source-IP to the same Destination-MAC/Destination-IP will always transfer though the same link and thus have the speed of one link.

Understand now
Thank you very much
