Interface Stopped DESTRIBUTING, possable flapping

xlameee

Hello

In my setup I have 2x40G adapter in LAGG0

I configured the switch with a port-channel and LACP
It is recommended to configure spanning-tree port type edge
when "switchport mode access" or
spanning-tree port type edge trunk
when "switchport mode trunk" or
spanning-tree port type edge network
when connecting to an other switch or router

1st I am not sure if this is why I am getting Interface flapping
and 2nd I am not sure what pfsense is in this case

thank you

Sounds like it isn't happy with the LACP or the links to the switch or something else.

Really hard to say from here.

Does the switch provide any information? What kind of switch is it? What kind of NICs are they?

@derelict hello

yes the switch is NEXUS 3132Q
the nics are Chelsio T580-SO-CR 2x40G adapter

at my other site I have exactly the same config just the switch is NEXUS 3132Q-V
and have no problem with LACP

Do you know in witch category fall under pfSense ?

Derelict

Which Category?

I would look at the switch logs and see what's there.

@derelict hello

I fixed it, but I am trying to understand how. Can you tell me what's exactly mean
"flapping" ?

thank you

The term flapping in computer networking generally beans a constant down, up, down, up progression.

We'd all be interested in knowing what you found and what you did to correct it.

@derelict It was a loop in my network. All I had to do is configure LACP and spanning tree protocol between both switches and flapping stopped.

well something like that
