#9885 closed defect (worksforme)

ar71xx switch traffic not flowing between ports - trunk (r27832)

Reported by: dave@… Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk
Keywords: Cc: dave@…


I was previously running 10.03.1-rc3. This problem is a regression since then. This problem appears both in the trunk version I'm on currently and 10.03.1-rc5.

Router ModelBuffalo WZR-HP-G300NH
Firmware Version OpenWrt Firmware Attitude Adjustment (r27832) /
Kernel Version

The issue is that traffic does not flow between the switch ports. Each port can contact the router, and (I think) each port can contact the wlan. But, two devices each hanging off a switch port can not see each other. To be more specific, the arps are not passed, so each of the systems' arp tables never get filled in. The router can see the arps on its eth0 interface, but they don't get seen by the clients.

root@bar$ ssh foo
ssh: connect to host port 22: No route to host
root@bar$ ssh router
root@router:# ssh foo

  • Resolution set to worksforme
  • Status changed from new to closed

you need to start with a fresh network config (check /etc/defconfig/wzr-hp-g300nh/network). your config does not include a switch config, so the switch is never fully initialized for allowing traffic to flow between ports.

Using the default vlan config in /etc/defconfig/wzr-hp-g300nh/network didn't work. But, disabling vlans entirely using that file did. Thanks for the help!
