Edge port problem

[PabloPW]

Hello,
I have a problem with spanning-tree beetwen HP 2530 and HP 1810.
On 2530 running configuration :

trunk 21-22 trk5 lacp
 sh spanning-tree trk5

                   |           Prio              | Designated    Hello
  Port  Type       | Cost      rity State        | Bridge        Time PtP Edge
  ----- ---------- + --------- ---- ------------ + ------------- ---- --- ----
  Trk5             | 20000     64   Forwarding   | ecebb8-afd280 2    Yes Yes

On 1810 is configure lacp too.

Why on HP 2530 spanning-tree showing Port Edge Yes??
