How to do ping from mesh interface ?

RouterOS General
1

I using a mesh bridge with eth1 wlan1

when I do ping from interface=wlan1 , I get no replay , but when I do ping from interface=bridge1 I get an answer.

only wlan1 is connected - so why I get no replay ?

how can I see that the replay came from WDS1 ?

Thanks ,

When a network interface is a member of a bridge, from an L3 perspective, you can’t treat it as a discrete interface any longer. Your 10.0.0.x network is defined on bridge1, so you can only ping from bridge1. I don’t know why you would expect anything else to work…

To verify that communication with 10.0.0.120 is happening over the bridge member port that you want, first check the ARP cache for the MAC address of the host in question, and then look through “/interface bridge host” for that MAC and see which interface that MAC was learned on (‘on-interface’); for example:

[admin@Unit2] > /interface bridge host print where mac-address=[/ip arp get [find address=10.0.0.120] mac-address]
Flags: L - local, E - external-fdb 
  BRIDGE           MAC-ADDRESS       ON-INTERFACE          AGE                 
  bridge1          00:11:22:AA:BB:CC WDS To Unit1          26s

O.k.
Thanks,

and if I want to save the interface "WDS To Unit1 " as a variable ?
how can I do this ?
i want to save the interface that go to 10.0.0.120 in a script and print it

I have try this

 :put [/interface bridge host find where mac-address=[/ip arp get [find address=10.0.0.120] mac-address ]]

and got this

*1

Thanks ,

Well, now you are asking a scripting question, which isn’t really what you started out asking. But in any case, the “*1” is an object ID. You need to use the ‘get’ command to retrieve specific information about a particular object:

[admin@Unit2] > :put [/interface bridge host get [:pick \
[[\... [/interface bridge host find where mac-address=[/ip arp get \
[[[[\... [find address=10.0.0.120] mac-address]] 0] on-interface]
WDS To Unit1
[admin@Unit2] >

For further questions about scripting, you might try the scripting forum and the scripting manual

thanks it help me with what I need

the “:pick” is what I didn’t remember

Thanks ,
