Hi,
I am newbie in Mikrotik. I need to change the MAC address of one of the ethernet interfaces, but I put the above mentioned command /interface ethernet set ether1 mac-address=xxx, I receive the message: “invalid item number” I am trying to put the command using winbox “New Terminal” feature. Can I do that in that way or I should login via Command line to put that command?

you have to enter correctly formed MAC address you can take an example from existing mac addess

follow these steps:

[admin@MikroTik] /interface ethernet> print 
Flags: X - disabled, R - running, S - slave 
 #    NAME        MTU   MAC-ADDRESS       ARP        MASTER-PORT        SWITCH    
 0 R  ether1-g... 1500  00:0C:42:56:98:14 enabled   
 1 R  ether2-l... 1500  00:0C:42:56:98:15 enabled    none               0         
 2  S ether3-l... 1500  00:0C:42:56:98:16 enabled    ether2-local-ma... 0         
 3  S ether4-l... 1500  00:0C:42:56:98:17 enabled    ether2-local-ma... 0         
 4  S ether5-l... 1500  00:0C:42:56:98:18 enabled    ether2-local-ma... 0         
[admin@MikroTik] /interface ethernet> set 4 mac-address=00:0C:42:56:98:66 

[admin@MikroTik] /interface ethernet> print 
Flags: X - disabled, R - running, S - slave 
 #    NAME        MTU   MAC-ADDRESS       ARP        MASTER-PORT        SWITCH    
 0 R  ether1-g... 1500  00:0C:42:56:98:14 enabled   
 1 R  ether2-l... 1500  00:0C:42:56:98:15 enabled    none               0         
 2  S ether3-l... 1500  00:0C:42:56:98:16 enabled    ether2-local-ma... 0         
 3  S ether4-l... 1500  00:0C:42:56:98:17 enabled    ether2-local-ma... 0         
 4  S ether5-l... 1500  00:0C:42:56:98:66 enabled    ether2-local-ma... 0         
[admin@MikroTik] /interface ethernet>

How do you revert any MAC address changes?

9

You set it back to the old MAC address using the same command. If you don’t know what that was you will have to reset to factory defaults.

10

Maybe this? Should have looked first =(

/interface ethernet reset-mac-address

or reset-mac (depends where you read)

http://wiki.mikrotik.com/wiki/Manual:Interface/Ethernet

11

is there a similar method that doesn’t involve reseting whole RB configuration, but for wireless interfaces?

12 
/interface wireless reset-configuration <wireless interface>

It resets the whole wireless interface config (including MAC address)

13

But cant use this on remote wireless client … How can i do it on remote client?

14

if you require to do this on remote client, you have to create script and schedule it to run in some time. then do reset, and re-apply your settings.

While you have feature available, use them with caution.
