CRS326+7.1b6+L3HW ... ?

Thu Aug 12, 2021 11:23 pm

Hi to all

i try to enable L3HW on very very simple setup
routing between two vlan's on CRS326

according to docs, CRS326 is supported

so, here is the config
/interface bridge
add name=BR-Switch vlan-filtering=yes
/interface vlan
add interface=BR-Switch name=vlan99 vlan-id=99
add interface=BR-Switch name=vlan200 vlan-id=200
/interface ethernet switch
set 0 l3-hw-offloading=yes
/ip pool
add name=pool1 ranges=192.168.99.100-192.168.99.200
/ip dhcp-server
add address-pool=pool1 disabled=no interface=vlan99 name=server1
/routing table
add fib name=""
/interface bridge port
add bridge=BR-Switch interface=ether1
add bridge=BR-Switch interface=ether7 pvid=99
/ip settings
set rp-filter=strict
/interface bridge vlan
add bridge=BR-Switch tagged=BR-Switch untagged=ether7 vlan-ids=99
add bridge=BR-Switch tagged=BR-Switch,ether1 vlan-ids=200
/ip address
add address=192.168.99.1/24 interface=vlan99 network=192.168.99.0
add address=192.168.200.31/24 interface=vlan200 network=192.168.200.0
/ip dhcp-server network
add address=192.168.99.0/24 dns-server=192.168.99.1 gateway=192.168.99.1 netmask=24
/ip dns
set allow-remote-requests=yes
/ip firewall filter
add action=fasttrack-connection chain=forward connection-state=established,related hw-offload=yes
add action=accept chain=forward connection-state=established,related
/ip firewall nat
add action=masquerade chain=srcnat out-interface=vlan200
i don't understand why L3HW wont work?
tried from scratch, netinstall, multiple reboots ...
nothing
transfer between vlans is capped around 180Mbps
tried with and without firewall, same thing

so i am out of ideas
anyone could help ?

Which exactly CRS326 model do you have? If it is CRS326-24G-2S+, then its 98DX3236 switch chip does not support Fasttrack and NAT offloading.
