Why this not working on 3.0 (on 2.9 works fine) ???

:foreach j in=[/ip arp find interface = ether1] do={/ip arp enable $j}

error message:

ambiguous value of interface, more than one possible value matches input

Please help me.

Hi,

I reset the system and followed this page:
http://wiki.mikrotik.com/wiki/Vlans_on_Mikrotik_environment

to configure

{admin@MikroTik] > /interface vlan add name=vlan-10 vlan-id=10 interface=ether5 disabled=no
[admin@MikroTik] > /interface vlan add name=vlan-20 vlan-id=20 interface=ether5 disabled=no
[admin@MikroTik] >
[admin@MikroTik] > /interface bridge add name=br-vlan10 disabled=no
[admin@MikroTik] > /interface bridge add name=br-vlan20 disabled=no
[admin@MikroTik] > /interface bridge port add interface=“vlan-10” bridge=“br-vlan10” disabled=no
[admin@MikroTik] > /interface bridge port add interface=“ether1” bridge=“br-vlan10” disabled=no
ambiguous value of interface, more than one possible value matches input

“ambiguous value of interface, more than one possible value matches input”
The message is confusing.

I reset and followed another page:
