Hello,
I’ve a CRS112-8P-4S which I’m using as a switch in bridge mode. It’s taking almost 100% of CPU when passing 300mbps of data.
I’ve tried to configure it to work using the bridge hardware offloading feature but without success, my knowledge in switching is a bit limited.
In a short:
- Management network is 10.10.0.0/24 VLAN 3100
- Port 1 act as trunk port
- Port 2 passes management VLAN and Data VLANS 3000, 4000 and 5000.
- Port 3 passes management VLAN and Data VLANS 3000, 4000 and 6000.
- Port 4 passes management VLAN and Data VLANS 7000.
- Port 7 passes management VLAN which is used to manage a local nobreak.
- Port 8 passes management VLAN which is used to access the switch locally.
The script is as follow:
# model = CRS112-8P-4S

Could you please set an example using the bridge hardware offloading feature? Or how to avoid so high CPU? I have to upgrade the traffic to 800mbps and afraid it’ll not work due to high CPU consumption.
Tks,
