Problem with Aggregation Link and Vlan

[AlessandroG72]

Network configuration has two switches:

Switch n°1 3Com Baseline Switch 2928 ip 10.10.0.110

Switch n°2 HP V1910-48G ip 10.10.0.105

In Switch 1 I have Vlan 1,20,100 with the following table:

Port 1-5 vlan 1 type=access untagged PVID 1

Port 6-10 vlan 20 type=access untagged PVID 20

Port 23-24 vlan 100 type=trunk untagged(100) tagged(1,20) PVID 100

In Switch 2 I have vlan 1,20,100 with the following table:

Port 1-5 vlan 1 type=access untagged PVID 1

Port 6-10 vlan 20 type=access untagged PVID 20

Port 24-48 vlan 100 type=trunk untagged(100) tagged(1,20) PVID 100

I have tried to create a static aggregation link between the two switches on port 23-24 and 24-48 but unfortunately the aggregation links did not work well and the ports were on standby status.

Can anybody please give me any advice on how to solve the issue?

Thanks, Alex
