link aggregation Alcatel switches

ChrisT

Hi all,

not sure if this question should be asked in this area, but feel free to move it if it shouldn't.

So, I have 3 Alcatel switches in stack mode and I am trying to connect them with a pfsense appliance XG-1541. The cxI0 an cxI1 ports have been configurred as lagg ports.

From each of these ports I have an 10gig sfp copper cable connected to a corresponding port in my Alcatel switch.

Unfortunately I haven't succeded in passing any traffic through these ports and this is why I am starting this topic. Does anyone know what kind of configuration I should have in my alcatel switch? I am configuring it both as static and dynamic lagg on my alcatel but I am not able to ping any address behind the switch.

thank you

What does ifconfig -v lagg0 on on pfSense show?

What is the status of the lagg from the switch's perspective?

I assume we're talking about LACP?

Yes, we are talking about LACP. Below are the two VLAN interfaces that seem to be up when I connect the cables.

The ifconfig command gives me the below:

It should look something like this:

lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=6500bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 00:08:a2:0a:59:3f
        inet6 fe80::208:a2ff:fe0a:593f%lagg0 prefixlen 64 scopeid 0xb 
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        media: Ethernet autoselect
        status: active
        groups: lagg 
        laggproto lacp lagghash l2,l3,l4
        laggport: igb4 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
        laggport: igb5 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>

Are you sure you set the lagg type in pfSense to LACP?

ChrisT

I believe the first screenshot is pretty much the same as what you posted. And yes, I’ve set LACP.

I believe the aggregate works but somehow I have an issue in routing. And this is because I’ve put the pfsense running side by side with my old checkpoint firewall (I have to let them work side by side for a while)

That ifconfig indicates LACP isn't even set on that lagg.
