Lacp across a vman

a customer is provided with a vman across our network.

They also have a direct wavelength between the 2 locations ..

They are now trying to setup lacp across both connections, but somehow the lacp packets don't make it across the vman link. As if ithey are eaten by the xos boxes in between.
All the obvious things have been checked, normal traffic ( without the wavelength ) across the vman work.

Does anyone know if there is a way ( perhaps using an acl policy) to push the packets not to the cpu but forward the lacp packets across the vman ?

Can you share your LACP configurations?

I believe LACP is a point to point direct protocol. What I mean by that is the ports that are directly connected need to respond to the LACP packets. I don't think you can tunnel them across a network.

Hi Erik.

You can't run LACP over any extreme box I have tested not in the sense that you can run it over vman. however you can do static lag, And you could use scripting with universal port to trigger down notifications on the ports if somehting happens on the transport vman. Think y.1731 or OAM . ( depending on the software of the switch ofcourse.)

I was able to do this by using an external encapsulation device. You can find a more detailed explanation in my blog.

Hello.

I had good work with ACL. Some like this:

* X440-48t-10G.31 # edit policy L2PT-to-port-1 entry l2tp-to-port-1 {

if {

vlan-id 500 ; # берет вышестоящий ИД (то есть из q-in-q)

} then {

redirect-port 1 ;

}

}



entry lacp {

if {

ethernet-type 0x8809 ;

} then {

redirect-port 1 ;

}

}

* X440-48t-10G.36 # configure access-list L2PT-to-port-2 ports 1 ingress

done!

* X440-48t-10G.37 # configure access-list L2PT-to-port-1 ports 2 ingress

done!

LACp work and VMAN work.

Thank you!

Hi,

The redirect-port was necessary up to 15.3.2. Since 15.3.3 and forward you should be able to tunnel LACP just like any other L2 PDU, using EXOS L2PT feature.

Hi, Stephane. Could yoy please give some examples of l2tp configuration? Thank you!

Hi.

Because manual about L2PT I have on EXOS 15.5, but I think this version is not really stable.
There is no Concept Guide or some configuration examples about L2TP in vesion EXOS 15.3.3 - 15.4

Thank you!

Hi,

That should be something like that:

entry lacp {

if {

ethernet-destination-address 01:80:c2:00:00:02 ;

} then {

replace-ethernet-destination-address 01:00:0c🇨🇨cc:cc ;

count lacp_ingress ;

}

}
