Hello!

It would be good to add an ability to view MAC address table of the switch (L2 Forwarding Database) for troubleshooting purposes. Sometimes it is needed to know whether switch learned MAC address or some remote side. Currently this is not possible.

ARP table is not an option, because remote side may not have an IP configured, and still it is needed to know if it is on link.

We are using VLANs and it is also needed to know in which exactly VLAN the MAC address does appear.

Let me know if any additional clarification needed on this request.

THanks!
Artem

/interface ethernet switch host print

/interface ethernet switch host print

This do not show required info.
It only shows Mikrotik's own MACs, but NOT learned.

Here is an example:
[artem@RTR01] > /interface ethernet switch host print
Flags: D - dynamic, I - invalid
# SWITCH MAC-ADDRESS PORTS TIMEOUT DROP MIRROR VLAN-ID
0 D switch2 E4:8D:8C:78:BF:D3 switch2-cpu 3m30s no no 1
1 D switch2 E4:8D:8C:78:BF:D8 switch2-cpu 3m30s no no 1

At the same time there are active peers, which I expect to appear in learned addresses list:

[artem@RTR01] > /ip arp print
Flags: X - disabled, I - invalid, H - DHCP, D - dynamic, P - published, C - complete
# ADDRESS MAC-ADDRESS INTERFACE
0 DC aa.bb.131.241 5C:5E:AB:0A:AE:F0 vlan762
1 DC aa.bb.131.249 5C:5E:AB:0A:AE:F0 vlan763

Thanks!
Artem

Hi Artem

What model are you using?

What ROS and Firmware version are you running?

Are all your VLAN's created in the switch menu? Or are they interfaces on the interfaces menu?


On my router at home (Temporarily RB951-2n) running 6.36RC21 (however I am not using VLAN's on my temp home router)
This shows:

[alexander@AJCN-Home-Router-01] > /interface ethernet switch host print

So your issue may be a bug or an implementation interaction with your VLAN's. With more information we may be able to build tests and see what appears to be happening.

If you are able to post your config we may be able to take a look further into that.

if you are using a bridge take a look on hosts table on bridge section

be sure you are using switch functionality

/interface ethernet switch host print

This do not show required info.
It only shows Mikrotik's own MACs, but NOT learned.

Well here it does... show the output of this command:
/interface ethernet export

What model are you using?
What ROS and Firmware version are you running?

Are all your VLAN's created in the switch menu? Or are they interfaces on the interfaces menu?

For me it does not look like configuration issue. But if anyone notice anything misconfigured - let me know please.

Thanks!
Artem

Well, the configuration specifies vlans on ether1, which is not part of your switch1.
OTOH, you specify configuration for these vlans on switch1.

I think it is not correct. I don't know what you want to achieve but you need to look at it again.

In your config, eth1 is a stand-alone interface which means that it is a layer 3 interface, so the switch will not track MACs. You see MACs on a L3 interface by looking in the ARP table.

If you MUST see MAC info regardless of layer 3, then you need to make a WAN bridge and move the VLAN interfaces onto that bridge. Then you should be able to see some MAC entries in bridge hosts display, but you'll only see things that are either already communicating with your WAN interface directly (thus in the ARP table anyway) or are sending broadcasts.

thats part of 802.1x-2010 subset. specifically 802.1AC and other portions.

For the list of layer2 addresses on a port try

/interface ethernet switch unicast-fdb print

I hope this helps.
