Try disable the AiProtection.

Try disable the AiProtection.

Yupe, tried that. No changes, error still persist.

 

[JInhanjr]

I disabled AI again, looks okay for now. Monitoring it for a few hours. still have 1 or 2 deadloop tho.

You can input commands as below via telnet or ssh: tc qdisc add dev vlan10 root pfifo
ex. tc qdisc add dev vlanX root pfifo for specific vlan

May I know what's the command for Telnet step by step? I did a telnet in but am not sure the proper command. Sigh.

Steps:
1. enable your telnet and telnet in
2. tc qdisc add dev vlan10 root pfifo
all steps are done.

What you need is to observe the dead loop message will appear again or not, this command is to add default qdisc for vlanX. And the root cause of this deadloop message is "no default qdisc on this vlan interface"

If you are interested in this, you can survey "tc" or "qdisc" to show your qdisc rule.

 

[JInhanjr]

i just input tc qdisc add dev van10 root pfifo. looks okay now.

Problem with asus is, Qnap doesn't support Load balancing RR on LAN port with my QNAP. I can live with that.
