HA -active -active -ditributed trunking (LACP) and VLAN tagging

Hi everybody

I am trying to achieve the following:
I want to connect a pair of AX1030 in an active active confiugration.
They will be connected to a pair of swithes running distributed trunking.
That allows me to create trunks as depicted in the diagram. For each load balancers the same color pairs are configured as trunks on the Load Balancer side.

What I need now is to tag the trunks created above so I can work on multiple vlans with this topology.

The question is: do I have to tag the ports or the trunk itself?
Common sense says it should be the trunks but … it is not very clear in the documentation

you need to tag the ports, see example below, first you configure the LACP trunk, then you nee to tag the interface.

AX2500#
AX2500#config

AX2500(config)\#inter
AX2500(config)\#interface e 3
AX2500(config-if:ethernet3)\#lacp trunk 1
AX2500(config-if:ethernet3)\#int e 4
AX2500(config-if:ethernet4)\#lac
AX2500(config-if:ethernet4)\#lacp tr
AX2500(config-if:ethernet4)\#lacp trunk 1
AX2500(config-if:ethernet4)\#wr mem

AX2500(config)\#vlan 100
AX2500(config-vlan:100)\#tagged ethernet 3 trunk 1
AX2500(config-vlan:100)\#tagged ethernet 4 trunk 1

Hi ssacchi

Ok so you tagg the trunk
I have tested distributed trunking and I had some strange results
Before I reach my conclusion I need to run a couple of more tests and I will get back to you with the results

thanks
