Netgear R7800 LACP Config Verification

Installing and Using OpenWrt
1

Hi, I am just getting started with OpenWRT and am fairly new to networking in general so I wanted to double check my LACP configuration. From my testing redundancy is working, I can unplug each cable and my Netgear GS724TP LAG monitoring shows the LAG stays up as long as one cable is connected. I haven't verified the bandwidth yet.

Note: Since the official Netgear R7800 OpenWRT firmware has swconfig as the default initial config I stuck with that, instead of trying to switch to DSA, so I can learn 1 thing at a time.

Let me know if you see any glaring issues and if you have any tips for verifying the LAG bandwidth.

Here is my config (all generated using LUCI GUI) -

config interface 'lan'
        option device 'br-lan'

I can't say if it is 100% correct or not, as I can see some parts of swconfig and some of DSA. However since you made the configuration only from Luci, it should be fine.
Regarding testing, I suppose you could enable bonding on another device connected on that switch. Otherwise use 4 devices and run iperf to both of them at the same time with multiple connections to make sure that all 4 links are utilized.

Which parts are DSA?

I exposed the switch_vlan ports as interfaces named LANPORT*, but that doesn't mean they are using the DSA config right?
That was the only way I could see to expose the switch_vlan ports to the bonding interface with swconfig.

The config device parts. E.g

config device
        option name 'br-lan'
        option type 'bridge'
        list ports 'bonding-LAGTest'
        list ports 'eth1'

And I can see here what seems to be redundant:

This seems like a mix of both but not exactly right.
Anyway, don't mind me, I am not that experienced with DSA, still learning, and I might be missing something.
