MAC address table size

Hi all,

Can anyone share with me a source of white/datasheet for Mikrotik models that show what their maximum MAC table size is?
I cannot find a resource anywhere that shows that information.

Basic models I’m after

  • RB1100
  • RB1100AH
  • RB1100AHx2
  • RB1200
  • CCR1009
  • CCR1036
  • CCR1072

Thank you.

The models listed are all routers.
So the RAM is basically the limit.

As a reference: I had a deployment with a CCR series w/ 16GB which had a huge amount of free memory when multiple connected cisco 2960xb (sdm prefer vlan) had a mac table overflow.

Hello

are you talking about

 /ip settings> set max-neighbor-entries=

.

from wiki:

max-neighbor-entries (integer [0..4294967295]; Default: ) Maximum number of allowed neighbors in ARP table.


Regards.

Thank you both for the prompt response.

I do realise these are routers and not switches, my concern is trying to find how many MACs the CCR1036-8G-2S+EM could possibly see say on a bridge interface (since it also has no switch chip) before it started having issues.

Thanks again.

of arp entries != # of MAC addresses

in case of integrated switches (if they are used for something) the limit is the switch processors scalability. then it turns to hub (broadcasts unknown frames). this is set by the type of switch chip.

if one does bridging, then the limit is the “CAM” table of the bridge. but i know of no measure that controls it in routerOS. the way in CLI to actually monitor this is to do

/interface bridge host print count-only
