@stephenw10 Agreed — no point re-testing 25.11.1. We'll do a fresh install
of 26.07 (skipping 25.11.1 entirely, landing from the 24.11 backup) and
capture the full set you asked for:
ifconfig -vvm lagg0
arp -a
truss ping <host-on-lagg>
dmesg
Re: what it's connected to — the LACP uplink (ix0 + ix1, 10G SR SFP+)
goes to a UniFi USG XG-16 (v7.4.1) on ports 13 + 14 (Aggregating /
LACP, 20G, Port Mode Infrastructure, Native VLAN Server Network, Tagged Allow
All). For reference, on the working 24.11 box ifconfig -vvm lagg0 shows the
LACP negotiation fully up:
laggproto lacp lagghash l2,l3,l4, active ports: 2, flapping 0
pfSense system: 90:EC:77:88:FB:AB, priority 0x01B2 (434)
switch partner: 74:AC:B9:AD:1E:DE, priority 0x001B (27)
both members ix0/ix1 in ACTIVE,COLLECTING,DISTRIBUTING /
ACTIVITY,AGGREGATION,SYNC
I'll capture the same on the 26.07 install and diff it against this.
Re: pre-existing flows surviving — you're right that's unexpected. We'll
re-examine that during the 26.07 test and report back with evidence either
way. Will post the full output here once the fresh install is done.
