Re: HAp AC LED status lights

I would also like to know what these indicate? My HAP AC lights are changing colors at regular intervals.  The WiFi led, for instance, holds orange for 3 seconds and then momentarily changes to red and then back to orange again. The 5th port with POE out changes is similar but will blink red between...

Re: hAP lite

Only RB941 but this is slower It is, actually, faster. CPU 650MHz (hAP lite) vs 400MHz (RB951-2n) More Mhz is not more powerfull. See the Honzam's comparation. http://forum.mikrotik.com/download/file.php?id=19763 The hAP lite is much faster than the 951-2n in my experience. Mikrotik tests the throu...

RSTP - Switch Chip instead of Bridged ports - RB2011/CRS125

Is there an equivalent to RSTP on the RB2011 or CRS125 that utilized the switch chip instead of the CPU? I am hoping to increase the throughput and skip the CPU entirely. Currently I have a RB2011 with two Uplinks but the throughput will not go beyond 175mbps. No firewall rules or mangle rules setup...

I do not have any insight into this issue but I have a similar observation from ubiquiti wireless devices vs mikrotik wireless. Attached is a smoking graph where the switch from a Nanostation M5 to a Sextant5 is apparent.

Is your goal to isolate clients at Layer 2?

Yes, definitely. I'm also not sure what an acceptable level of broadcast/multicast traffic would be on a medium sized bridged network.

You would effectively shut down your network....IPv4 requires Layer2 multicast and broadcast for ARP to work along with a number of other protocols.
