NMM's LLDP topology view shows our aggregation stack as three separate switches instead of one logical unit. Vendor-level LLDP messages differ per stack member (they all announce their real chassis IDs). Any way to teach NMM to fold them? I saw a docs page mention chassis-id aliasing but I can't find the config example.

Chassis-id aliasing lives in Settings → Network Discovery → Chassis Aliases (bit buried). Add a rule mapping each stack member's chassis id to a canonical id and NMM folds them in the topology view within one polling cycle. Docs page is docs.netxol.example/nmm/topology/chassis-aliases if that helps.

That fixed it, thanks. Might be worth surfacing the aliasing UI when the topology view detects multiple LLDP neighbours announcing similar names — right now you have to know to look.
