Need help with vlan across HP 5406zl switches

[Shoana]

I need some help with the HP 5406zl switches, actually I need help in allowing VLANs to work between switches in my case I am having one 6600ml-24g fiber switch and two 5406zl switches and here the whole scenario is that our admin had created 2 VLANs but then he had just assigned the ports as "Untagged Ports" for the group and it is now making segment traffic, it is setup in the following way:

• A = VLAN 100
• B = VLAN 200
• C = VLAN 300

Here Each 5406zl switch is having RJ-45 in the slot A-B-C respectively and each of them is having 24 ports but then here module d is not having any information for the VLAN and I am not having any issues in running a cable between the switches and port D1, so is there a way by which I can enable VLAN 100 on both switches for the communication between them, is there anyone who can help me out???

In that case you can just Mark it as Tagged on d1 as well as on both the switches, just try it out and it should help.
