Hello!
How to get some info from lan interfaces included in bridge?
For example, in Mikrotik, I can take channel load from any interface, but in owrt there is only the logical interface of the bridge itself, and there are simply no physical ones to choose from.
In version 22, I see SNMP for each port as well.
not all, there is lan3 and and lan4?
or your router have only 2 lan ports?
It has 3, I didn't picture them all for space reasons. It's just an example to show it works.
(Just because it has more, doesn't mean one monitors them all anyway.)

i have 2 different routers with OpenWrt 22.03.2 on it, and the same behavior here
no physical interfaces included in the bridge are shown

Seems to identify them fine. eth0 and eth2-4 belong to br-lan bridge.

thanks for answer.
it looks like owrt thinks that all ports in the bridge group are one device, because I don't see lan2-4 in the output
root@OpenWrt:~# ifconfig | grep eth
eth0 Link encap:Ethernet HWaddr 4C:60:DE:D1:5B:35
eth1 Link encap:Ethernet HWaddr 4C:60:DE:D1:5B:34
eth1.1 Link encap:Ethernet HWaddr 4C:60:DE:D1:5B:34
is it possible to somehow change this behavior or are these features of the operating system operation with specific switch chips ?
If the interfaces are labeled lan why do you grep for eth?

They're not listed as in a bridge in SNMP, they're PHYs.
As noted, they're lan - not eth.
ok ok.
root@OpenWrt:~# ifconfig | grep lan
br-lan Link encap:Ethernet HWaddr 4C:60:DE:D1:5B:34
wlan0 Link encap:Ethernet HWaddr 4C:60:DE:D1:5B:36
no separate lan ports only logical entity of bridge
- How is this related to SNMP?
- What device do you have?
- What version of OpenWrt are you running?
as I wrote in the first message, I don't understand why snmp doesn't give me values from lan ports included in the bridge, although it is possible in other operating systems
- What you're doing isn't related to SNMP - perform an SNMP lookup with e.g.
snmpwalk - Please answer other questions

I assume that owrt simply cannot work with individual ports included in this kind of switch chips.
if there are owners of these routers out where, they can confirm / refute this statement.

I have a MediaTek-based chip. I don't think all Atheros devices were migrated to DSA, I have a few that still use swconfig (WD MyNet N750 for example - using an AR9344 SoC).

yes, looks like Atheros AR7241 and Atheros AR7161 doesnt have DSA support (thats why a dont have lan 2-4 interfaces in my system)
thank you!
