waliulislam commented 5 years ago

Ping does not work for l3 vlan interface when vlan has lag port consists of more than one physical port.

Found the root-cause. This is a SAI issue that affects the Dune chip. We will fix this issue internally.

any news on this? This bug is now 4 month old

GarrickHe commented 5 years ago

This has been fixed awhile back and verified internally. I need @waliulislam to close this issue because I can't do it.

Ah ok it sounded similiar to the known issues of the 3.1.0 release with the 4200 series (L3 vpn)

@disaster123 ,

I'm not sure about L3 VPN. This issue has to do with the LAG PDUs that get sent out when a dynamic LAG gets created between peers and how those PDUs are handled on the 4200.

Thanks, Garrick

@GarrickHe i'm referencing http://archive.openswitch.net/docs/3.1.0/openswitch_opx_310_rel_notes.pdf "Known issues S4248FB-ON and S4248FBL-ON platforms: • Traffic does not pass for L3 VLANs over LAGs (aggregated links consisting of more than one port). This is being investigated and will be fixed in an update."
