Strange ping behavior

RouterOS General

Hello

I've found very strange ping behavior on my RB2011:
[admin@RB20111] /tool sniffer packet> /ping 192.168.1.30
HOST SIZE TTL TIME STATUS
192.168.1.30 timeout
192.168.1.30 timeout
sent=2 received=0 packet-loss=100%

[admin@RB20111] /tool sniffer packet> print

And one more thing: with 6.6 firmware there is no ping. BUT! with 6.4 ping pass with the same 129.0.4.177 address visible in sniffer.

I have just found something similar in ROS6.4mips while testing vlan’s on the switch chips & QinQ.
