Port mirroring not working

Hello all,


i own various routerboards, and im actually trying to test the port mirroring function on
a RB 433UAH, it has a switch chip with two ports eth2 an eth3.

I have followed the wiki link, where the basic functions provided by my unit is explained.
Basically i cannot used the host, rules or other advanced options due to my switch chipset.
But the basic and supported option seemed to be failling.

[admin@MR-Core] /interface ethernet switch> print
Flags: I - invalid

NAME TYPE MIRROR-SOURCE MIRROR-TARGET SWITCH-ALL-PORTS

0 switch1 IC-Plus-175D ether3-dsl eth2-lan


I did some sniffing on both interfaces, and i didnt see the eth3 traffic on the eth2. What am i
meessing ??

RouterOS version is 5.8.

Thank you
Javi
