High bandwith consumption in bridge mode and high latency

HI JoseCasanova, 

If the updates are the cause of your issue , We do have an option to manage the updates . 

Pattern updates are updated automatically by default. Various patterns for different models like Sophos AV, IPS, WAF, and ATP can be updated. The page also allows you to update patterns or schedule how often it will auto-update.

You can update patterns:

• Manually
• Automatically

Update Patterns Automatically

To update patterns automatically, navigate to System > Administration > Updates and enable Auto Update in Pattern Download/Installation section. You can schedule how often you want to receive updates. The parameters can be set as shown in the image below.

Update Patterns Manually

When you wish to update the Database/signatures and also AV then you may select UPDATE PATTERN NOW .

Taken from KB article 123277

Hope this would resolve your issue 

Thanks and Regards

Hi Jose,

That is strange, do you see any dropped or error packets on the interface?

Take SSH to XG and go to option 4. Device console.

Execute, show network interfaces. Post the output.

Thanks

Thanks Aditya and Sachin for your answers.

The updates I was referring are windows updates and other high consumption bandwidth apps (in the LAN side).

Sachin, the output of the command shows:

As you can see, there is dropped packages on the Bridge interface. Today we are going to configure the physical interfaces from autonegotiation to 1000 Mbps Full Duplex, in the Sophos XG and in the Cisco ASA, and Switch Core.

Do you have any other recomendation that I could applied?

Thanks again for all your help.

Regards,

Jose

Hi Jose,

When you capture dropped packets on a physical interface, you must check the physical connectivity between the two ends; here, physical cables. Replace the cables with a fresh one and verify if the drops increase.

Thanks

Hi Sachin,

thanks again for your answer. However, I checked the patch cords, which were freshly opened for the deployment. Besides, this client has two branches with same configuration, and in both locations are experience the same issue.

let me know if there is another workaround.

Regards,

Jose

Hi Jose, 

If the Bandwidth utilization is high due to Windows Update , I would recommend you to apply QOS on application "BITS" under application filter and Enable QOS for Application filtering on the Firewall rules. Also the value you insert is in KB so 128KBPS=1mbps bandwidth.

This would enable te updates to pass through  XG appliance with Specified Bandwidth so it would not hamper your network when all systems updates simultaneously.

Thanks and Regards

Aditya Patel 

Jose,

make sure to configure Speed on both Switch and XG side. Also can you share output from the following commands:

netstat -s

ethtool -S "portname"

You should execute these commands from CLI > Option 5 > Option 3

Thanks

Hi Luk,

thanks for your reply. The Sophos XG is only connected to the LAN port of the bridge, and is not handling any traffic, so I hope this commands shows historic events:

 Hello again,

I've connected the Sophos XG to the Bridge, and managed to get the commands on production state. After applying the fixed speed, the issue is still happening:

Regards,

Jose,

what about CPU/RAM utilization?

I think you should open a ticket with support. It can be a problem that XG is too small, NIC driver issue or a bug inside the code.

Let us know!

Thanks
