Bonding Speed Problem

RouterOS General
1

Hi,
I’m trying to increase bandwith by bonding. I tried 802.3ad dynamic, Balance-rr and Balance-xor. All give the same speed (about 950mbps)
Mikrotik 802.3ad dynamic Speed: 950Mbps CPU: %4-6
Mikrotik Balance-rr Speed: 950Mbps CPU: %90-95

interface/bonding/print detail 
Flags: X - disabled; R - running 
 0    name="Master" mtu=1500 mac-address=00:00:00:00:00:00 arp=enabled arp-timeout=auto slaves=ether19,ether20 
      mode=802.3ad primary=none link-monitoring=mii arp-interval=100ms arp-ip-targets="" mii-interval=100ms 
      down-delay=0ms up-delay=0ms lacp-rate=30secs transmit-hash-policy=layer-2-and-3 min-links=0

But when I don’t use mikrotik and do lacp on netgear I get about 1.5Gbps (Speed 1.5Gbps only in Balance–rr. Others about 950mbps)
NetGear Balance-rr Speed: 1.5Gbps
NetGear 802.3ad Speed: 950Mbps

What am I doing wrong?or missing?

I drew the topology instead of explaining it.

Balancing-rr is the only bonding method that sends packets from the same connection across different interfaces in the bond. But that isn’t hardware offloaded, which is why the CRS CPU maxes out. 802.3ad is offloaded to the switch chip, but will send all packets belonging to the same connection across the same interface. And you are running only a single iperf TCP connecton, so you’re getting no more than 1G (minus overhead) throughput. Use 802.3ad or balancing-xor (both are hardware offloaded on the CRS3xx switches) and run multiple iperf connections (-P option) and you’ll see 1G+ total throughput.

Veeam will take backup over this connection. As far as I understand from your description, the speed will not exceed 1g+ as it will create a single connection in veeam.

4

Yes. Unless Veeam has a way to use multiple TCP connections for a single host-backup, that is what will happen.

Thanks for the information..

Did this answer help you?

Yes .. He explained to me that I couldn’t do what I wanted to do …
