LACP link beetween A500 and 2510G - problem

Hello

I know topic but I have (I think) a bit more complicated config

Two switches connected using LACP trunk. SW60 is a A5500 switch and SW57 is a ProCurve switch.

In my network vlan 50 is a Mgmt network and only in this vlan I prefer to have "mgmt" traffic.

[SW60]dis interface Vlan-interface 50
Vlan-interface50 current state: UP
Line protocol current state: UP
Description: Vlan-interface50 Interface
The Maximum Transmit Unit is 1500
Internet Address is 192.168.50.50/24 Primary

[SW60]dis interface Bridge-Aggregation

 IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 4431-920b-6dd2
 Description: LACP uplink

Why trunk doesn't carry traffic? how to troubleshoot it more deeply?

 

Regards

Slawek
