VLAN TCP PERFORMANCE

RouterOS General
1

Hi,

I have problem in the troughput wit VLAN. I use 2 Vlan and Static Roution with 2 CCR1036-12G-4S


The problem is I do a test with no VLAN and is working great, I do a test with VLAN with UDP and is working great but when I do the test with TCP the performance is 1/3 that I can have only about 300Mbits/s. Also I use a bridge for all VLAN.
Side A

interface bridge
add l2mtu=1590 name=bridge1 protocol-mode=none
add l2mtu=1586 name=bridge901 protocol-mode=none

/interface ethernet
set [ find default-name=sfp1 ] auto-negotiation=no comment

/interface vlan
add interface=sfp1 l2mtu=1586 name="VLAN 901" vlan-id=901

Same config on side B


Thanks

Can you also post what vlan is in what bridge ?

and why are you modifying the l2mtu on the bridge ?

VLAN901 in Bridge901, bridge1 no Vlan

I don’t modify the L2MTU is automatic detected, I think that is because one bridge have VLAN an the other bridge don’t have it.


Thanks
