Need Help Please - Problem creating a Link Aggregation between HPv1910 and HP2910-al

[PeterDa]

Hi All,

I am trying to create a Link  LACP between two switches.

I have made an attempt at setting up a link aggregation between 2 switcheswith no luck :         HP 2910-al Switch (Port 39-40)    < ========== > HP 1910-16G  Switch (Port 15-16) .

I have my Workstation connected into the HP1910-16G. There is an uplink from the HP1910-16 to the HP2910-al which works fine.   When I remove the uplink and connect the 2 switches using these aggregated ports I lose connection.

We tried to connect the LACP HP2910-al to a cisco switch and this worked.

Here is the configurations I made to the 2 switches :

HP 1910-16G SWITCH Configuration :

Here is the HP1910-16G Switch Vlans :

1
 VLAN 0001
 GE1/0/1-GE1/0/14, GE1/0/17-GE1/0/20
 
2
 trk2
 BAGG1, GE1/0/15-GE1/0/16
  

BAGG1 is an aggregation port which comprises of Port 15-16
The Aggregation Link Interface Type is Dynamic which enables it as LACP.

Here is the full configuration from the HP2910:
