Flooding DHCP REQUEST

neesonqk · November 4, 2021, 2:10pm

Just found one of my device keeps flooding DHCP REQUEST to my router, and the device finally is identified as my Apple TV 4k (the first gen), it looks like every few seconds it send a DHCPREQUEST, and I also found this topic that someone complains the same problem, I just wonder whether this affects my router? will this cause any problem like network interruption problem after a long while? Or I just can leave it.

I have tried to put a static IP as following,

but it never stop the flooding stuff.

The frequency of 2 DHCPREQUEST per minute is not exactly flooding, so it won't affect the performance of the router in any way.
It seems that your apple device is not respecting the DHCP renew half lease time interval, which is the normal period for a device to ask for a renewal.
Just to verify uci export dhcp

neesonqk · November 4, 2021, 3:18pm

I see, and I have done a verification here, the 'leasetime' is in HOURS right? so here it's 48 hours.

trendy · November 4, 2021, 3:43pm

The leasetime is definitely not in hours, if you don't specify the unit (s,m,h,d) I guess it defaults to seconds. You don't need to fill it in though, the default lease time for the whole pool will be used which is 12 hours.

flygarn12 · November 4, 2021, 5:10pm

Apple-TV does that, I have made the same question here in this forum a looong way down in all the forum treads.

For reference.
Flood the log…I did that by accident once. Since I didn’t use wifi on wrt3200acm I thought of the brilliant idea to use the wifi led to indicate some other data traffic.
But the use of wifi led resulted in an unexpected “kernel wifi led unlawful used” error on the router that was sent by tcp to the logserver and the data sent to the log server actually made the wifi leds blink to indicate data traffic and that sent the kernel errors for the blinks that was caused by the blinks to the log sever.
A couple of seconds later a gibabit network derailed big time and completely brought down the wrt3200acm and the log server.
That is log flooding!

neesonqk · November 5, 2021, 3:33am

@trendy You are right , it's in seconds, I have removed and left it as 12 hours by default. But still as you mentioned, my apple tv does not respect the setting at all, and keeps throwing renewal requests 2 time per mins.

@flygarn12 That was what I worried about in the beginning, log flooding is also a flooding lol. Not sure if you have solved it, but I realised that Apple uses both wireless and ethernet at the same time when the device got wired up, which means it has reserved 2 IPs at the same time, just because with ethernet connected, you can't see the wireless setting, it still is there under the hood, that's y I can't see the requests been eliminated by setting a static IP, because I set the static IP address to ethernet port only, Apple starts to use wireless port instead to send leasing renewal, that's kind of ridicules and buggy to me.

Allocating both a static IP finally appeases my apple tv to make more nosies to my router, seems this is the only solution for now. I have other android TV boxes and none of them behaves like apple, and all of them can do projection or streaming like a charm without any problem, just don't understand why apple does that.

jaromanda · November 5, 2021, 3:38am

a very common question about all things apple

flygarn12 · November 5, 2021, 9:22am

Ok interesting, I didn’t know that!?

neesonqk · November 5, 2021, 9:59am

Yes, very sure. you can do a simple test as I did,

Connect Apple TV to WiFi
Plugin ethernet cable
Put TV box to sleep mode
Wait for a while (within 10 minutes maybe)
You will see leasing renewal requests from the ethernet port, why I know it's from ethernet port? later you'll know. And you can also record the MAC address from the log, because later you'll see a similar MAC address just with the last character different.
Now, set a static IP to that MAC address.
Hmmm... Apple starts to do the magic thing, it then starts to send renewal requests from wireless port! with a very similar MAC address as mentioned in step 5, now you must know why the requests are from ethernet port in step 5

trendy · November 5, 2021, 10:07am

Can't you disable the wifi when the ethernet is plugged in?

flygarn12 · November 5, 2021, 11:13am

Apple is great at some things, like general working functions, especially connection between different Apple devices and iCloud.

But you are not really allowed to be in charge of the system…

neesonqk · November 5, 2021, 4:06pm

No, you can't, the wifi settings are just gone when cable is plugged. Another workaround is, forget the connected wifi before the ethernet is plugged in....
