Hello.
I would like to use RB493, but I must be sure, that all ports are fully managementable separately (like on RB800 or RB2011)
Because what I found, it use similar switch chip like daughter board RB816, or RB433 and what I heard, it’s not possible on them.
Thank you 
all ports are separate. (in all mikrotik products).
There is a connection from a portgroup to kernel in products having a lot of ports. This is not making anny impact on separating ports, but could sometimes be an performance issue. (but i dont think this is an issue in a 493, as a high performance device would be something else) You will se this as different l2mtu values in different port groups
Thank you for the reply.
Because someone said me, that he tried to set routing on two pots of RB816 which was on one switch chip, but it didn’t worked… The same on RB433.
So it’s not true? We have one RB800+RB816 so it will be better solution then RB493?
(There will be main input connection, local ethernet, 3 Ubnt and 3 wifi)
it might not working for him, but i think probem must have been config. Not ports 
OK, hope you are right 
Another question, if I got it right, when I don’t use the switch IC, the bandwidth is limited by connection to CPU?
I mean:
eth1 has 100Mbs
eth2-eth5 has 100Mbps together
eth6-eth9 has 100Mbps together ?
If speed to CPU is 100mb/s - Yes. (if traffic is from one switch group to another) there should be som docs about this around. I just dont remember where. You can read about rb1100 here : http://www.mikrotik-routeros.com/2010/05/rb1100/ and http://forum.mikrotik.com/t/rb1100-full-gigabit-throughput/37560/2
Thanks a lot!
Can also someone confirm it?
Because second engineer still stand up for his opinion that it doesn’t work and I don’t have any free RB to test it
