802.1Q between switches hp2524/2424 and cisco 3524

I have 3 vlans, def vlan (id 1) and vlans 96, 192. here is the 802.1Q trunk port connected to a 2524 port 1 (which belongs to the 3 vlans, untagged for vlan 1, tagged for vlans 96, 192). on hp and cisco switches , 3 ports belong to vlan 96, 3 ports to vlan 192.

my pb is that , vlan 1 is transmitted, but not vlans 96, 192, i don't understand why

Does the Cisco have VTP set to transparent or does the HP support VTP? You might also try disabling VLAN Pruning.

Is "show vlan" showing expected information on Cisco?
