DHCP error message

Thu Aug 01, 2019 3:53 pm

Hi,

How can I fix this DHCP error message?


"dhcp, error temporary moving client ether1 from slave to master port, update your config !!!"

Running v6.44.5 long-term on a RB4011, other than having dhcp server on the bridge interface directly, I can't figure out what is the problem.

Put the dhcp server on the bridge and not on physical interfaces being member of a bridge.

I actually have the dhcp server on the bridge, which has all ethernet ports included in it (except sfp-plus).
[admin@MikroTik] > /ip dhcp-server print detail  
Flags: D - dynamic, X - disabled, I - invalid 
 0    name="dhcp" interface=bridge lease-time=7h address-pool=default-dhcp bootp-support=dynamic bootp-lease-time=forever authoritative=yes use-radius=no lease-script="" 
      allow-dual-stack-queue=no 

[admin@MikroTik] > /interface bridge export
add bridge=bridge comment=defconf interface=ether2 learn=yes
add bridge=bridge comment=defconf interface=ether3 learn=yes
add bridge=bridge comment=defconf interface=ether4 learn=yes
add bridge=bridge comment=defconf interface=ether5 learn=yes
add bridge=bridge comment=defconf interface=ether6 learn=yes
add bridge=bridge comment=defconf interface=ether7 learn=yes
add bridge=bridge comment=defconf interface=ether8 learn=yes
add bridge=bridge comment=defconf interface=ether9 learn=yes
add bridge=bridge comment=defconf interface=ether10 learn=yes
add bridge=bridge interface=ether1 learn=yes

I've moved my ether1 on top in the bridge port list, I'l check if that makes a difference.

Edit: nope, drag and drop works in winbox, but if I try to drag 'ether1' to the top, it goes for 1 second and returns to the bottom of the port list.

Re: DHCP error message  [SOLVED]

Ooops... sorry, I was too quick reading your post. The error deals with dhcp client. That might be a heritage from the original config when ether1 was WAN.
It looks like you configured your device for bridging only or get WAN through SFP. So it should be safe just to remove that dhcp-client.

Indeed, I was too lazy removing the dhcp client config. I only use static WAN ip addresses.
Thx a lot !
